  • Tropical Storm Jerry forms in the Atlantic

    [ad_1]

    Tropical Storm Jerry has formed in the central Atlantic. It’s the tenth named storm of the 2025 Atlantic hurricane season.

    What You Need To Know

    • Tropical Storm Jerry formed in the central Atlantic

    • It’s expected to strengthen into a hurricane

    • Jerry likely won’t impact the U.S.


    Tropical Storm Jerry has maximum winds of 45 mph and is quickly moving westward at 24 mph. It’s expected to slow down and eventually turn northward during the next couple of days.

    Jerry is expected to strengthen into a hurricane as it moves through a favorable environment. Its core will pass near the northern Leeward Islands late Thursday into Friday, bringing the potential for gusty winds and heavy rainfall later this week.

  • October’s Harvest Moon rises tonight

    [ad_1]

    Our next full moon, and the first one of the astronomical fall, will rise above the horizon late tonight.

    What You Need To Know

    • October’s full moon is a supermoon and will appear about 30% brighter and 14% larger

    • It is called the Harvest Moon

    • Unobstructed views of the horizon allow for best sightings


    This full moon is called the Harvest Moon because it is the full moon that falls closest to the autumnal equinox (Sept. 22). What makes this so unique is that between 1970 and 2050, there are only 18 years when the Harvest Moon occurs in October. The last time was in 2020, and the next time will be in 2028.

    Historically, it’s called the full Harvest Moon because it provides bright light for several evenings in a row to help farmers gather their crops.

    Supermoon

    October’s full moon is a supermoon, and according to NASA, it will appear approximately 30% brighter than normal and 14% larger than normal. This is because of the moon’s proximity to Earth. During a supermoon, the full moon is at “perigee,” which means it is at its closest location to Earth all month. 

    The moon will officially be full at 11:48 p.m. EDT Monday, so you’ll have to stay up late to catch it at its peak. Here’s the forecasted cloud cover. 

    Cloud cover across the United States expected at midnight on Oct. 7, 2025.

    Other names of the moon

    There is some discrepancy about the nomenclature of the October full moon. Naming conventions date back to the Native Americans of the northern and eastern United States, who kept track of the seasons. 

    Here are some other names given to the full October moon:

    • Hunter’s Moon: This is the traditional time to hunt
    • Falling Leaves Moon: Name given to express the changing and falling leaves, signaling the onset of fall
    • Dying Grass Moon: A Gaelic name that signifies the end of the growing season
    • Drying Rice Moon: A Dakota name given for when rice is harvested and dried
    • Freezing Moon: A time of the year when the first frost occurs

    The best viewing will be after sunset on Monday and early morning on Tuesday. To find the best time to view in your area, check out the moonrise calculator. Be sure to find a place with unobstructed horizon views for the best sights.

    The next full moon will be the Beaver Moon, which occurs on Nov. 5, 2025.

  • Tropical development happens closer to the U.S. in October

    [ad_1]

    The peak of the 2025 hurricane season was nearly three weeks ago, and the tropics have responded, with three hurricanes — Gabrielle, Humberto and Imelda in just that time period. Two of those hurricanes even achieved Category 5 status, with winds of 155+ mph.

    With two more months left in the typical hurricane season, how does the month of October play out with storms? 

    What You Need To Know

    • Tropical activity slightly decreases in October

    • The development regions shift to the Caribbean and eastern U.S. coastlines

    • Track patterns change, and most systems track toward the northeast


    While activity decreases slightly in October, the month sees most of the storm formations closer to the U.S., particularly in the Gulf, Southeast Coast and Caribbean. These are locations where water temperatures remain well above the 79° threshold. 

    Most systems track toward the northeast, with it likely that many stay off the eastern coastlines. However, there have been landfalling systems in past October months.

    Milton

    Milton was one for the record books, even before ever making landfall. While it formed in the Bay of Campeche on Oct. 5, it quickly intensified into a hurricane. It underwent rapid intensification in the Gulf, going from a Category 3 hurricane to a Category 5 hurricane with maximum winds of 180 mph in less than 24 hours. It ties Hurricane Rita for the most intense Atlantic hurricane ever.

    It made landfall near Siesta Key, Fla., as a Category 3 hurricane, with winds of 120 mph. Prior to landfall on Oct. 7, the outer rainbands spawned tornadoes in central and southern Florida. 126 tornado warnings were issued in Florida, the second most tornado warnings ever issued in one day, and the most ever in Florida or from a tropical system. 

    Parts of Hillsborough County saw flooding from hurricanes Debby, Helene and Milton last year. Hillsborough County is hosting several meetings to gather information from residents and businesses about the flood impact of those storms. (Spectrum News)

    As Milton moved inland, heavy rain created a flash flood emergency north of the center of circulation, including the cities of St. Petersburg, Tampa and Clearwater. St. Petersburg – Albert Whitted Airport reported 18.54 inches of rain from Milton. 

    Michael

    Michael first became a tropical storm on Oct. 7 and quickly intensified into a hurricane a day later. It then became a major hurricane on Oct. 9 as it moved through the warm waters of the Gulf.

    Michael made landfall near Panama City, Fla. on Oct. 10 as a Category 5 hurricane, making it the third-strongest landfalling hurricane in the U.S. on record and the strongest storm to strike the Florida Panhandle. 

    (Spectrum News)

    It destroyed many houses in the Florida Panhandle, and storm surge flooded the coast. Farms suffered, leading to a loss in cattle and crops, and Michael caused $4.7 billion in damage to the Tyndall Air Force Base. As Michael weakened, it moved further into the southeast, bringing wind damage and flooding to Alabama, Georgia and North Carolina.

    It total, we saw $25 billion in damage from Michael, and around 60 deaths.

    Matthew

    Hurricane Matthew in 2016 was one of the deadliest storms ever to strike the Atlantic, causing a humanitarian crisis in Haiti. It intensified into a hurricane on Sept. 29 before exploding into a Category 5 storm 24 hours later., the first Category 5 hurricane since Hurricane Felix in 2007.

    Matthew made landfall in Haiti as a strong Category 4 storm on Oct. 4 and then in Cuba on Oct. 5.

    Forecasts took it close to the Florida and Georgia coastlines as a Category 3, but the center of the storm did not make landfall. The western side and the inner eyewall remained just offshore. Matthew weakened to a Category 2 hurricane late on Oct. 7 and then to a Category 1 hurricane by Oct. 8.

    It made landfall near McClellanville, S.C., making it the first hurricane to make landfall north of Florida in October since Hurricane Hazel in 1954.

    Sandy

    Developing in the Caribbean Sea on Oct. 22, Sandy made two landfalls before heading toward the U.S., one in Jamaica and one in eastern Cuba.

    It continued through the Atlantic, parallel to the East Coast, and made a northwest turn, slamming into the Northeast. Even though winds were only at 80 mph at landfall in New Jersey, Sandy was a large storm that brought intense flooding.

    Many cities in New Jersey flooded, and authorities had to evacuate towns. Sandy also flooded seven subway tunnels in NYC, the biggest disaster to happen to the subway system since it was built in the early 1900s.

    In West Virginia, rain turned to 3 feet of snow for some areas, leading to downed trees and hundreds of thousands of power outages.

    Overall, Sandy became one of the deadliest cyclones to hit the Northeast, killing 160 people, and the fifth costliest storm in recorded history with $65 billion in damage.

    Wilma

    2005 had numerous notable storms, and one of those storms was Hurricane Wilma. Wilma developed on Oct. 17 in the Caribbean Sea, and intensified quickly into a Category 5 hurricane before weakening to a Category 4 before its first landfall on Cozumel, Mexico.

    Wilma had the lowest pressure ever recorded in a hurricane in the Western Hemisphere, going from 982 millibars to 882 millibars in just 24 hours. It then moved northeast, making its second landfall as a Category 3 hurricane at Cape Romano in southwestern Florida.

    Over 3 million people lost power, including 98% of Miami’s metro area, and Wilma destroyed or damaged tens of thousands of homes and cars in southern Florida. Water from the storm surge submerged 60% of Key West, leaving many homes uninhabitable.

    Homeowners cover their roofs in blue tarps to cover damage cause by Hurricane Wilma in Broward County, Fla., Wednesday, Oct. 26, 2005. Frustration mounted on the third day of recovery from Hurricane Wilma, with the scramble for gas, ice, food and water causing long lines and traffic snarls, which prompted renewed criticism of storm planning and response. Miami-Dade County’s mayor called the relief effort “flawed.” (AP Photo/Wilfredo Lee)

    Wilma caused $19 billion in damage and killed 30 people.  

    After Wilma, a major hurricane didn’t strike the U.S. until Hurricane Harvey in 2017, and a hurricane did not strike Florida until Hurricane Hermine in 2016.

  • Hurricane Humberto is quickly weakening

    [ad_1]

    Hurricane Humberto continues to weaken quickly . It’s going to become post-tropical soon.

    Humberto formed on Wednesday, Sept. 24. It’s the eighth named storm of the 2025 Atlantic hurricane season.

    What You Need To Know

    • Humberto is becoming disorganized as it battles strong wind shear

    • No direct impacts to the U.S. are expected

    • It’s bringing gusty winds and heavy rain to Bermuda


    Humberto is a Category 1 hurricane with maximum winds of 80 mph. It’s moving north-northwest at 18 mph across the western Atlantic. 

    It’s turning northeastward as it combats strong westerly wind shear, becoming more disorganized. It should weaken and turn post-tropical by Wednesday or Thursday.

    It’s not a threat to the U.S. other than rough surf and dangerous rip currents along the east coast.

  • Can two tropical systems collide? The Fujiwhara Effect explained

    [ad_1]

    Hurricanes Imelda and Humberto are churning in the western Atlantic. As of Tuesday morning, they are located a little over 400 miles from one another.

    Initially, it could appear that the two storms will merge to generate a mega-hurricane, but this is not the case, due to the Fujiwhara Effect. 

    What You Need To Know

    • The Fujiwhara effect is when two storms orbit around a common point

    • It’s an unusual circumstance, especially among tropical systems

    • It usually takes place in the spacious Pacific Ocean, but can occur in any ocean


    So why does this happen? In short, the two low pressure systems rotate around a common center point. 

    What is the Fujiwhara Effect?

    Named for Sakuhei Fujiwhara, a Japanese meteorologist who first noticed storms’ interactions in the 1920s. He theorized that two storms could rotate around a common point and influence tracks of the storms. Fujiwhara was proven correct.

    In some instances these storms look like they are “dancing” with one another. 

    Bay News 9’s Chief Meteorologist Mike Clay says we should not be concerned about these storms colliding and forming a mega-hurricane. “In the Atlantic, if two tropical systems are close enough, they can ruin the environment for both, just like we are seeing right now with Humberto and Imelda. There just isn’t enough ocean space.”

    The smaller or weaker storm will usually circle around the bigger one, as the larger storm will eventually dominate or potentially even fully absorb the smaller system.

    Imelda, in this case, is the larger storm and is expected to fully absorb Humberto over the next day or so. Wind shear, or the change in wind speed and direction with height, is usually created from the interaction, killing one or both storms.

    2023 Atlantic Ocean Fujiwhara Effect

    Clay says this effect is rare and commonly occurs in the Pacific Ocean because it is the larger ocean, but it can happen in any ocean. 

    Nearly two years ago, a similar occurrence was taking place in the Atlantic Ocean, albeit with weaker storms. Tropical Storms Philippe and Tropical Storm Rina were both located east of the Leeward Islands. 

    They began to do the “dance” of the Fujiwhara Effect and eventually, the stronger storm – Philippe weakened Rina. 

    On Sept. 28, 2023, Tropical Storms Philippe and Rina east of the Leeward Islands, began the Fujiwhara Effect “dance.” (NOAA)

  • Tropical Depression Nine expected to become a tropical storm soon

    [ad_1]

    Tropical Depression Nine is moving toward the Bahamas and expected to become a tropical storm soon. The next name on the list is Imelda.

    What You Need To Know

    • Tropical Depression Nine is moving toward the Bahamas

    • It’s expected to strengthen into Tropical Storm Imelda

    • It will bring impacts to the southeastern U.S. early next week


    Tropical Depression Nine has maximum winds of 35 mph. The storm is almost stationary, moving northwest at 2 mph toward the Bahamas. The depression this evening remains fairly disorganized, with convection mainly oriented in a north-south fashion with only a hint of banding on the northern side.

    It’s expected to strengthen into Tropical Storm Imelda and then eventually into a hurricane as it heads north toward the southeastern coast. There is still above-average uncertainty in the details of the long-range forecast. It is notable to point out the system has been moving slower than anticipated over the last 12-24 hours, and this could have significant implications on its ultimate track.

    In general, models agree that the presence of Hurricane Humberto to the east will result in a weakening of steering currents, causing the system to slow down and meander near the southeast U.S. coast on Tuesday. The offical NHC track now favors a slower storm and a track that turns sharper to the east, keeping it farther away from the U.S. coast. Fewer models are showing a landfalling tropical cyclone.

    Even with a high degree of uncertainty, there is a threat of heavy rainfall early next week from portions of the east coast of Florida northward into the Carolinas, which could cause flash, urban, and river flooding.

    Tropical Depression 9 is expected to be at or near hurricane intensity when it is closest to the southeast U.S. coast early next week, where there is a risk of storm surge and wind impacts. Although it is too soon to be specific about track and intensity, residents should closely monitor the latest forecast updates and ensure that they have their hurricane plan in place.


    The cone of uncertainty displays where the center of a storm could be located. It does not predict which areas may feel the storm’s impact. Anyone outside but near the cone should be on alert and make storm preparations.

    Models show the system approaching the coast of Georgia and South Carolina and slowing down. It could make landfall or turn back out into the Atlantic before moving inland.


    Spaghetti models or plots show a series of individual computer forecast models together on one map. They are useful to give insight into whether multiple models are in agreement on the path of the storm but they do not address the storm’s forecast intensity, winds, flooding and storm surge potential or other data. Tap here for more details on how to best use these models.

    Tropical Storm Warnings are in effect for the Bahamas. Tropical Storm Watches are in effect up Florida’s East Coast.


    The threat for significant rainfall and flash flooding is expected across parts of the Southeast throughout early next week regardless of where Tropical Depression Nine goes.

  • Potential Tropical Cyclone 9 could impact the Southeast next week

    [ad_1]

    Potential Tropical Cyclone 9 has formed in the western Atlantic near the Bahamas. 

    What You Need To Know

    • Potential Tropical Cyclone 9 has formed

    • It’s expected to strengthen into Tropical Storm Imelda

    • It could make landfall along the southeastern coast next week


    It is a Potential Tropical Cyclone with maximum winds of 35 mph. It is moving northwest at 9 mph across the western Atlantic. 

    It’s expected to strengthen into Tropical Storm Imelda and then eventually into a hurricane as it moves north toward the southeastern coast. It could make landfall anywhere from Georgia to the Carolinas early next week.

    The forecast for Potential Tropical Cyclone 9 still has a lot of uncertainty, as it should interact with Tropical Storm Humberto, making the long-term track and intensity forecast more difficult than usual. The entire southeastern U.S. coast should be monitoring it closely.

  • Gabrielle accelerates into the northern Atlantic

    [ad_1]

    Hurricane Gabrielle is still a major hurricane as it pulls away from Bermuda. It rapidly intensified Monday, and remains a powerful storm.

    It formed Atlantic on Wednesday, Sept. 17. It’s the seventh named storm of the 2025 Atlantic hurricane season.

    What You Need To Know

    • Gabrielle is moving away from Bermuda

    • It’s still a major hurricane

    • A Hurricane Warning is in effect for the Azores


    Gabrielle is now a Category 3 hurricane with maximum winds of 115 mph. It is currently moving east-northeast at 25 mph over the open Atlantic. 

    Gabrielle will continue to move east out into the open waters of the Atlantic for the rest of the week as it transitions into a post-tropical cyclone. It will stay far enough from Bermuda to avoid any significant impacts, but it will bring large swells to Bermuda and the East Coast of the U.S.

    Vertical wind shear continues to slowly increase over the hurricane, and shear will increase further while Gabrielle moves over cooler ocean
    waters, and the latest guidance shows a slightly faster rate of weakening than earlier. The NHC intensity forecast follows suit, showing steady weakening through the next 2-3 days, though Gabrielle should still be a hurricane when it moves across the Azores late this week as a hurricane with Hurricane Warnings in effect.

  • Tropical Storm Humberto forms in the Atlantic

    [ad_1]

    Tropical Storm Humberto has formed in the central Atlantic. It’s the eighth named storm of the 2025 Atlantic hurricane season.

    What You Need To Know

    • Humberto has formed in the Atlantic

    • It’s a tropical storm with max winds of 40 mph

    • It’s expected to become a hurricane


    Humberto is a tropical storm with maximum winds of 40 mph. It is currently moving west-northwest at 15 mph toward the western Atlantic. 

    It’s expected to continue its track toward the northwest or west-northwest during the next couple of days, staying well north of the Leeward Islands. It is expected to strengthen into a hurricane over the weekend. 

    The forecast for Humberto still has a lot of uncertainty, as it could interact with another tropical wave near the Caribbean, making the long-term track and intensity forecast more difficult than usual. It’s not a threat to the U.S. at this time.

  • Fall officially arrives with the autumnal equinox

    [ad_1]

    Fall has officially arrived. Summer has come to an end, meaning cooler and shorter days are on the horizon. 

    What You Need To Know

    • Fall begins Monday, Sept. 22

    • The 2025 autumnal equinox happens at 2:19 p.m. ET

    • The largest daily loss of daylight occurs in September



    The change in seasons occurs with the solstice or the equinox determined by the Earth’s tilt and orbit around the sun. 

    What is the equinox?

    The Earth is tilted at a 23.5-degree angle, and as it travels around the sun, the Earth’s axis is tilted toward or away from the sun.

    During the equinox, the Earth’s axis and its orbit line up, allowing the sun’s rays to shine directly on the equator. This means that both hemispheres get an equal amount of sunlight.

    Meteorological Fall vs. Astronomical Fall

     

    The meteorological seasons are calendar-based, whereas the astronomical seasons rely on the Earh’s position to the sun. 

    Meteorological fall occurs from Sept. 1 to Nov. 30. The meteorological seasons are broken down evenly into 3-month periods based on temperature and weather cycles. 

    Astronomical fall typically starts between Sept. 21 and Sept. 23. This varies because of leap years, which can shift the start date by a day or two. 

    Why do we lose so much daylight?

    We have been slowly losing more and more daylight since the summer solstice in June, and will continue to lose more daylight until the winter solstice in December. The largest daily loss of daylight occurs in September, especially as the autumnal equinox approaches.

    The Earth’s 23.5-degree tilt is the main reason we see daylight changes throughout the year. Your latitude also plays a role as well.

    This time of year, the Northern Hemisphere tilts away from the sun, leading to a decrease in daylight. Areas located closer to the equator will see less variation in daylight hours as opposed to areas located closer to the North Pole.

  • When will you see the first freeze this fall?

    [ad_1]

    Leaves are changing, and the first day of astronomical fall is next Monday, Sept. 22. Most of the country will begin to see cooler temperatures in the coming weeks, and some won’t have to wait long.

    Even though winter doesn’t begin until December, cold air and freezing temperatures arrive well before then for most of the U.S.

    What You Need To Know

    • The Northern Plains and Intermountain West usually dip down below freezing before September is over

    • Interior New England  and the Great Lakes also see freezing temperatures before most of the country

    • Cold air arrives in Florida, the Gulf Coast and the Desert Southwest last



    Winter arrives at the time time every year on the calendar, but not on your thermometer. Every year is different. The maps below give a good idea of when you can expect the first freeze where you live based on the 1991-2020 U.S. climate normals.

    The maps below show the ‘median,’ or average date of the first freeze. This is when you could expect the first freeze to arrive during a ‘normal’ year. The next one shows the ‘earliest 10%’ which shows a scenario of when colder air arrives early, about once every 10 years. And the last map shows the ‘latest 10%,’ so during a warm year when cold air arrives late.

    Northeast

    Most of the Northeast and New England see the first freeze before or during early fall, in September or early October. The mountains and high elevations across interior New England and the Adirondacks average freezing temperatures sometime in September, with the rest of the Northeast getting freezing cold sometime during October or early November.

    Midwest

    The Upper Midwest and Northern Plains also get in on the cold early. Around the Great Lakes and Dakotas, the first freeze typically arrives during September or early October. Further south the wait isn’t much longer. Freezing air usually arrives to the rest of the Midwest sometime before Halloween.

    Northwest

    There are many microclimates across the Northwest, so the arrival of cold air varies. Across the Rockies and Intermountain West, some areas experience cold year-round and as early as August and early September. The Pacific Northwest might not see freezing temperatures arrive until late October or November thanks to the maritime influence. 

    Southwest

    The Southwest has a variety of climates as well, so the temperatures differ greatly during the fall and winter. The Desert Southwest and coastal California don’t see the arrival of cold air until late in the season, sometimes not until December. Once you get into the high desert and Southern Plains, it arrives much earlier, around October or early November.

    Southeast

    If you live in the Southeast, it still gets cold, especially away from the large bodies of water. In the Appalachians and areas away from the Gulf and Atlantic coast, freezing temperatures usually begin before Thanksgiving in late October or early November. The Gulf Coast and Florida, however, wait much longer, with freezing temperatures not arriving until late November or December. In South and Central Florida and southern Texas, freezing temperatures may never even arrive.

  • Tropical Storm Gabrielle forms in the Atlantic

    [ad_1]

    Tropical Storm Gabrielle has formed in the central Atlantic. It’s the seventh named storm of the 2025 Atlantic hurricane season.

    What You Need To Know

    • Gabrielle has formed in the central Atlantic

    • It’s expected to become a hurricane this weekend or early next week

    • It’s not a threat to the U.S. at this time


    Gabrielle has maximum winds of 45 mph and is currently moving north-northwest at 22 mph. It’s not expected to strengthen much in the next 48 hours as it moves through unfavorable conditions with strong upper-level winds keeping Gabrielle disorganized.

    This weekend, Gabrielle should enter a more favorable environment for strengthening, and it’s forecast to become a hurricane by this weekend or early next week.


    The cone of uncertainty displays where the center of a storm could be located. It does not predict which areas may feel the storm’s impact. Anyone outside but near the cone should be on alert and make storm preparations.

    Gabrielle is out in the central Atlantic, far from land. Although it’s moving north-northwestward, the motion is uncertain during the next several days until a better defined center forms. 

    As of now, it doesn’t look like a threat to the Caribbean or the U.S., but it could move near Bermuda next week.


    Spaghetti models or plots show a series of individual computer forecast models together on one map. They are useful to give insight into whether multiple models are in agreement on the path of the storm but they do not address the storm’s forecast intensity, winds, flooding and storm surge potential or other data.

  • When to expect the best fall foliage

    [ad_1]

    Every fall, people travel far and wide to go ‘leaf-peeping.’ The goal is to catch the leaves at peak color to see all the vibrant reds, oranges and yellows that Mother Nature has to offer.

    Weather plays a primary role in knowing when and where to go.

    What You Need To Know

    • Weather plays a significant role in fall foliage


    • Heat and soil moisture determine foliage timing and intensity


    • Stressed trees will lose leaves earlier or later than normal


    Right place at the right time

    The first step of successful leaf-peeping is being at the right place at the right time. All other factors aside, this is the average time of the year around the U.S. that you can see peak fall colors according to Explore Fall.

    (Explore Fall)

    Aside from the Florida peninsula, the Gulf Coast and parts of the desert Southwest, most of the continental U.S. sees color change during fall.

    Weather’s role

    The weather determines whether the fall foliage comes out early, on time or late every year, but what role does it play?

    Heat and moisture are the biggest factors that influence fall foliage. The summer weather helps give an idea of when colors will pop, but the weather during September and October are the biggest influencers.

    Here is how soil moisture and air temperature affect fall foliage.

    Weather impacts on fall foliage

    (Explore Fall)

    A prolonged late-spring or severe summer drought that leads to dry soils in the fall not only affects the timing, but the quality of the colors. Drought and drier soil puts a higher stress on the trees, dulling down the colors and forcing them to lose their leaves sooner.

    Heavy rainfall and wet soils in the summer and fall can delay the colors’ arrival by a few days, or even weeks. The later arrival time can produce better fall colors.

    Colder and below-normal temperatures bring out fall colors early, while prolonged summer heat and above normal temperatures delay the colors.

    According to the USDA Forest Service, “a succession of warm, sunny days and cool, crisp but not freezing nights seems to bring about the most spectacular color displays.” In other words… typical fall weather.

    Current fall foliage

    Here is a map of the current fall foliage around the U.S.


    In some parts of the country, leaves have already started turning. The first areas to see color are typically further north and at higher elevations, including parts of the Upper Midwest and Northern Plains, the Mountain West and interior Northeast.

    Parts of New England are in a severe drought, with much of the mountain west under an extreme or exceptional drought, which could cause the trees to lose leaves early and mute the colors.

    7-Day foliage outlook

    Here is a look at Explore Fall’s 7-day foliage forecast and what the foliage is expected to look like in a week from now.

  • The peak of the 2025 Atlantic hurricane season is here

    [ad_1]

    Hurricane season in the Atlantic Ocean spans June through November, and this year was forecasted to be near to above average.

    What You Need To Know

    • The 2025 Atlantic Hurricane Season was forecasted to be near to above average

    • Through early Sept. 2025, there have only been six named storms

    • The climatological peak of hurricane season is on Sept. 10


    However, as we approach the climatological peak of the season, we’ve only had six named storms. 

    2025 Atlantic Season predictions

    Both the National Oceanic and Atmospheric Administration (NOAA) and Colorado State University (CSU) made their seasonal forecasts back in May and updated them in August. The latest outlooks predict an above-average season: 13 to 18 tropical cyclones (down from 13 to 19 named storms) for NOAA and 16 named storms for CSU (down from 17 to 24 named storms).

    The new predictions include the six named storms we’ve already seen. The average number of named storms is around 14 per season.

    How the season began

    Tropical Storm Andrea formed on June 23, 2025. This marked the latest start to a season since 2014. 

    Next, Tropical Storm Barry formed toward the end of June and made landfall in Veracruz, Mexico. 

    After Barry, Tropical Storm Chantal impacted the southeastern U.S. The storm made landfall in South Carolina on July 6, bringing tropical storm force-winds and flooding rainfall to the Carolinas.

    Tropical Storm Dexter followed, and next, Hurricane Erin. Erin became a large and powerful Category 5 storm. The storm stayed well off the coast of the U.S., but it brought dangerous rip currents to most of the eastern seaboard.

    Tropical Storm Fernand formed in mid-August and stayed offshore. Here’s a look at the 2025 hurricane season so far. 

    Since then, there has been a lull in tropical activity. 

    Still a lot of the season to go

    In September and early October, storms are most likely to form in the central Atlantic and the Caribbean. However, as more frontal boundaries move through the U.S. at this time, it’s possible for tropical cyclones to develop along old fronts in the Gulf of Mexico and off of the southeast coast. 

    “We are just coming up on the halfway mark of the hurricane season, usually the time of peak activity,” says Dr. Frank Marks, a meteorologist in the Hurricane Research Division of NOAA/Atlantic Oceanographic and Meteorological Laboratory. 

    Don’t let the lull in the Atlantic lull you to sleep. As we approach the peak with quiet conditions, there’s still plenty of time for more storms to develop.

    Notable September and October tropical cyclones

    Even though many may be focused on fall, hurricane season is ongoing! There have been many tropical cyclones that have formed and made landfall in September and October. 

    Just last year, Hurricane Milton formed in October and rapidly intensified into a powerful Category 5 storm in the Gulf of America. This was the strongest tropical cyclone ever recorded over the Gulf since Hurricane Rita in 2005. Milton made landfall as a Category 3 storm near Siesta Key, FL.

    While the outlook over the next seven days looks quiet in the Atlantic, make sure you’re focusing on the forecast as conditions in the open waters can change. Tracking the Tropics.

  • Tracking powerful hurricane Kiko as it heads towards Hawaii

    [ad_1]

    Kiko formed off the coast of southern Mexico from a tropical wave. It became a tropical storm on Aug. 31, making it the eleventh named storm of the eastern Pacific hurricane season. Kiko intensified into a hurricane on Sept. 2. 

    What You Need To Know

    • Kiko is the eleventh named storm of the eastern Pacific hurricane season

    • It remains a major, powerful hurricane

    • Models have Hurricane Kiko moving close, but to the north of the Hawaiian Islands next week


    Kiko intensified into a Category 4 hurricane on Sept. 3. It weakened to a Category 3 hurricane with winds of 115 mph during the morning hours on Sept. 5, but by the afternoon it had re-intensified back into a Category 4 hurricane.

    It currently has maximum winds of 140 mph. It is moving west-northwest at 10 mph and is located roughly 1000 miles east-southeast of Hilo, HI.

    It is a much smaller storm than Hurricane Erin. Hurricane-force winds extend only 25 miles out from the center, with tropical storm-force winds extending 70 miles out from the center. 


    Models have Kiko taking a west-northwesterly track over the weekend into next week, coming close to Hawaii. 

    While it’s too soon for impact details, the cooler waters near the Aloha State should weaken Kiko greatly. We’ll continue to monitor the track and provide updates. 


     

    Storms that have come close to Hawaii

    Hurricane Hone passed just to the south of the Big Island of Hawaii in 2024 as a Category 1 hurricane with winds of 85 mph. Here are other cyclones that came close to the islands.

    Eastern North Pacific names

    Central North Pacific differences

    The National Hurricane Center monitors tropical activity in the Atlantic and North Eastern Pacific Ocean. If a storm forms between 140° West longitude and the International Date Line, it is the responsibility of the Central North Pacific Warning Center, located in Honolulu, HI. 

    There is a contrast in the names used in the Central Pacific compared to the Eastern Pacific and Atlantic. One list is composed of twelve names. 

    The names are used one after the other. When the bottom of one list is reached, the next name is at the top of the next list. Below is the current list. 

    It is interesting to note that if a storm forms in the Eastern North Pacific and is named in that basin, it will retain its name even if it moves into the Central North Pacific. For this reason, we are tracking Hurricane Kiko, since it formed east of 140° West longitude.

    Tropical Storm Akoni and Tropical Storm Ema formed in the Central North Pacific in 2019. Hurricane Hone brushed past Hawaii in 2024.

    This list will continue to be used until there is a storm named Wale. Three other lists have been generated by the World Meteorological Organization and are at the ready if needed. Hurricane Iona and Tropical Storm Keli formed in the Central North Pacific in 2025.

    Just like in the Atlantic and Eastern North Pacific, if storms are impactful, they can be retired. Four storms have been retired in the Central North Pacific. 

    • Iwa (1982): Retired after impacting Hawaii.
    • Iniki (1992): Retired after affecting Hawaii.
    • Paka (1997): Retired after affecting various islands in Micronesia.
    • Ioke (2006): Retired after impacting Micronesia.

  • September’s ‘Corn Moon’ rises this week

    [ad_1]

    Our next full moon, and the final one of the astronomical summer, is set to rise above the horizon this week on Sunday, September 7th.

    What You Need To Know

    • September’s full moon will rise this weekend

    • It is called the ‘Corn Moon’ this year

    • Unobstructed views of the horizon allow for best sightings


    This full moon is called the Corn Moon as opposed to the Harvest Moon which traditionally is the full moon that falls closest to the autumnal equinox (September 22nd). It just so happens that the next full moon will occur on October 6th so it gets the name Harvest Moon this year.

    The moon will officially be full at 2:09 pm EDT Sunday, so it won’t be seen until hours later when it rises above the horizon after sunset.

    This year’s Corn Moon will actually coincide with a lunar eclipse for much of the Northern Hemisphere (Europe, Africa, and Australia), but no eclipse will be visible across the U.S. Other countries can expect a long-lasting “blood moon” similar to what America saw back in March earlier this year.

     

    Potential cloud coverage Sunday evening. (weathermodels.com)

    The name of the moon is a reference to the corn harvest, which typically happens this time of the year across North America.

    The best viewing will be after sunset on Sunday.  To find the best time to view in your area, check out the moonrise calculator. Be sure to find a place with unobstructed horizon views for the best sights.

    The next full moon will be the Harvest Moon, which occurs on October 6, 2025. As mentioned earlier, the Harvest Moon is whatever full moon falls closest to the Fall Equinox. Usually that is in September, but every four or five years, it happens in October.
