  • Hazardous Bay Area heat finally winds down with warnings downgrade

    Hazardous Bay Area heat finally winds down with warnings downgrade

    [ad_1]

    The blistering, record-setting heat that has lingered over the San Francisco Bay Area for the past week will start to loosen its grip Monday, with officials downgrading local Excessive Heat Warnings to Heat Advisories.

    While the temperatures will still be warmer than average on Monday, they will finally begin to decline this week starting Monday evening, the National Weather Service said.

    With the higher confidence of deeper onshore flow Monday evening, all Excessive Heat Warnings were downgraded to Heat Advisories in effect until 11 p.m. Monday, officials said.

    The Bay Area office of the National Weather Service posted about the downgrade on X early Monday morning, noting that the Heat Advisory for the coast was no longer in effect.   

    The Excessive Heat Warning was initially extended for much of the Bay Area through Monday, as a late heat wave sizzles the region for the seventh day in a row.  

    Temperatures across lower elevations were actually a couple of degrees warmer than this time Sunday morning, which may lead to a slight increase in the temperature forecast for Monday. However, temps at higher elevations are running a few degrees cooler than 24 hours ago, hinting that lower level temps in the atmosphere are beginning to gradually cool.

    Temperatures Monday will likely fall off more quickly Monday evening as onshore flow is restored. However, for the day, moderate heat risk will persist across much of the region away from the coast in the interior East Bay, the Santa Cruz Mountains, the North Bay Mountains, and Eastern Santa Clara Hills. 

    Heat records were matched or broken Sunday across the Bay Area and beyond, surpassing temperatures from a heatwave that hit nearly 100 years ago, according to the National Weather Service. 

    San Rafael hit the highest temps in the Bay Area on Sunday, at 107 degrees. The closest temperature match there was when the city was 95 degrees back in 2023. Also in Marin, the town of Kentfield hit 102, beating out the previous high of 97 in 1930. 

    In Sonoma County, Santa Rosa reached 102 degrees, matching the same temps for this day in 1930. 

    In Napa County, highs at Napa State Hospital topped 102, also beating out the heatwave of 1930 when it was measured at 96 degrees. 

    Downtown San Francisco also beat its previous record of 94 in 1992, by reaching 97 degrees. At the airport it was 98 degrees, beating 2023’s high of 92. 

    In the South Bay, Redwood City reached 102 degrees, 3 degrees higher than its record of 99 in 1987. San Jose hit 103, beating out 2023’s 95-degree record. And the Salinas airport clocked a high of 98 degrees, matching 2023’s high. 

    The NWS noted that all these numbers are preliminary and official temps will be released from the National Centers for Environmental Information.

  • Excessive heat warning extends into weekend as late heat wave scorches Bay Area

    Excessive heat warning extends into weekend as late heat wave scorches Bay Area

    [ad_1]

    An excessive heat warning has been extended for much of the Bay Area into the weekend, as a late season heat wave continues to bring record-breaking temperatures to the region.

    The National Weather Service announced Thursday afternoon that the warning remains in effect for the North Bay interior and coastal ranges, the entire East Bay and South Bay, eastern San Mateo County and the Santa Cruz Mountains, along with interior Monterey County, the southern Salinas Valley and San Benito County until 11 p.m. Saturday.

    Meanwhile, a heat advisory remains in effect for coastal regions, including San Francisco, along with the North Bay valleys and northern Salinas Valley, also until 11 p.m. Saturday.

    “Hot and dry conditions continue with dangerous heat and potentially critical fire weather conditions for the remainder of the work week. The heatwave did peak the last couple of days, but impacts from Moderate to Extreme Heat Risk at times, will be felt into the weekend,” said a Weather Service statement on Thursday.

    On Wednesday, preliminary data showed at least three Bay Area communities set or exceeded previous temperature records for that date. In San Rafael, the high reached 106 degrees, tying the previous set in 1980.

    Meanwhile in Napa, the high reached 103 on Wednesday, breaking a record also set in 1980 of 102 degrees.

    In San Jose, the high on Wednesday reached 106 degrees, breaking the day’s record of 96 degrees set in 1980 and 2012.

    According to CBS News Bay Area Chief Meteorologist Paul Heggen, Wednesday’s high is the hottest recorded October temperature ever in San Jose and the 8th hottest since record-keeping began in 1893. The hottest temperature in San Jose ever recorded was 109 degrees, set back in Sep. 2022.

    The Weather Service said relief from the heat may begin early next week, but temperatures are expected to stay above normal for interior locations.

  • Thousands without power as storms sparked thunderstorm warnings, watches across DC area – WTOP News

    Thousands without power as storms sparked thunderstorm warnings, watches across DC area – WTOP News

    [ad_1]

    The D.C. region dealt with a round of powerful showers and thunderstorms Saturday afternoon and evening after dealing with the heat.

    Listen live to WTOP for traffic and weather updates on the 8s.

    The D.C. region dealt with a round of powerful showers and thunderstorms Saturday afternoon and evening after dealing with the heat.

    A Severe Thunderstorm Watch was issued through 9 p.m. and a Flood Watch was issued through 10 p.m. but were canceled by the National Weather Service just before 8 p.m.

    A destructive Severe Thunderstorm Warning was initially issued for Loudon County until 5:45 p.m. NWS reported that the severe and destructive thunderstorm blew through portions of Loudoun County with winds nearing 80 mph and some radar-indicated hail.

    One of those storms was expected to bring up to 80 mph wind gusts to portions of the region, hail and more to the area.

    A warning was also issued for sea farers along the Tidal Potomac through 7 p.m. as troubling wind gusts enter the region.

    The storms caused trees to fall Anne Arundel, Carroll, Frederick and Prince George’s counties in Maryland and Fairfax, Fauquier, Loudoun, Prince William and Stafford counties in Virginia.

    Officials across the DC-Baltimore area have cancelled several evening events due to the presence of severe weather.

    In the District, officials overseeing the Mubadala Citi DC Open said the semifinals have been suspended following heavy rainfall and wind gusts upwards of 60 mph.

    Baltimore Mayor Brandon Scott and the city’s Arts Council also said this weekend’s “Artscape 40” festivities, which usually happen despite dreary weather, have been cancelled through Saturday night.

    “Artscape is a rain or shine event, but this evening’s weather calls for dangerous conditions, and we must prioritize safety above all else,” the office said. “The safety and well-being of our attendees, staff, volunteers, vendors, and the City’s support teams are of paramount.”

    Thousands without power

    Thousands across the region were waiting for power to come back on. Most of those people are in Northern Virginia.

    Dominion Energy told WTOP that as of 7 p.m. it had nearly 4,000 homes and businesses without power in Loudoun County and another 4,500 homes and businesses in Fairfax County. NOVEC saw similar numbers, reporting over 3,000 outages for its customers.

    Dominion also said 5,000 customers were in the dark in Fauquier County.

    Hot end to workweek

    Some parts of the D.C. area experienced dramatic temperature hikes during Friday’s excessive heat warning, with the heat index possibly reaching 110 degrees in the District, Prince George’s and Anne Arundel counties in Maryland, and Arlington, Falls Church and Alexandria in Virginia. Temperatures at Dulles Airport reached 101 degrees, surpassing the previously measured record of 100 degrees.

    D.C. Mayor Muriel Bowser activated an extended heat emergency starting Friday until Tuesday, Aug. 6 or until conditions improve. During the emergency, additional outreach teams from multiple city agencies will conduct welfare checks and additional cooling centers are opened to help residents cool down from the heat.

    Schools in Fairfax County, Virginia, canceled all outdoor activities on fields and courts through 8 p.m. Friday due to the heat. The parks and recreation department in Prince George’s County, Maryland, also canceled the majority of its outdoor programs.

    This latest heat wave comes after the D.C. area had its fourth hottest July on record and the third hottest since 2011, according to Evans. The D.C. area has already seen 36 days at or above 90 degrees, almost reaching the annual average of 40.

    In Maryland, almost 1,000 people have gone to an emergency room since May for heat-related illnesses, and 14 have died, according to the Maryland Department of Health.

    In Virginia, over 2,500 people have gone to the emergency room since May, according to the Virginia Department of Health.

    State officials are urging people to limit their time outdoors and drink water.

  • Dangerous heat expected to spread up West Coast, break records, according to forecasters

    Dangerous heat expected to spread up West Coast, break records, according to forecasters

    [ad_1]

    Temperatures are expected to soar along the U.S. West Coast on Friday and Saturday, the National Weather Service said, warning that “dangerous heat” will likely spread up the West Coast as it intensifies.

    Forecasters said temperatures will be 15-30 degrees above average for much of the West Coast Friday, and “numerous record-breaking temperatures can be expected through the next few days,” the weather service said.

    Heat watches and warnings are in place across multiple states, including large swaths of California, as well as parts of Nevada, Arizona, Oregon and Washington.

    In parts of California and southern Oregon, temperatures could blast into the triple digits, the weather service said. California is expected to experience some of the worst effects of the heat wave on Saturday, forecasters said, with temperatures likely to reach into the 110s.

    “Locally higher temperatures into the 120s are possible in the typical hot spots of the Desert Southwest,” the National Weather Service said.

    In Death Valley, known as one of the hottest place on Earth, temperatures could reach up to 129 degrees, forecasters predicted. 

    In Los Angeles, the National Weather Service issued a “Red Flag Warning” in effect until late Friday night due to “hot, dry and windy conditions.” The warning signifies increased risk of fire danger. The weather service warned residents to use caution with open flames as the dry conditions could fuel the spread of fire.

    The heat wave coincides with the Thompson wildfire, which engulfed Butte Country in Northern California this week and forced thousands to flee their homes. Evacuation orders were downgraded to warnings on Thursday.

    As of Friday, the fire was 46% contained, according to the California Department of Forestry and Fire Protection.

    Over the weekend, the excessive heat and humidity will shift east to the mid-Atlantic and the Southeast, with temperatures expected to break into the high 90s and low 100s.

    The National Weather Service encouraged people to stay vigilant, noting that heat impacts can compound over time and pose a threat to health and safety. The above-average temperatures can be expected to last into next week, forecasters said.

    “It is imperative to stay hydrated, out of direct sunlight, and in buildings with sufficient air-conditioning when possible,” said the weather service. “It is also equally as important to check on the safety of vulnerable friends, family, and neighbors.”

    California Gov. Gavin Newsom’s office said earlier this week that the state was taking steps to ensure the most vulnerable Californians had access to resources, including cooling centers.    

    Heat-related deaths have been on the rise in recent years. In 2023, an estimated 2,300 deaths were linked to excessive heat, breaking previous records, an AP analysis found.

    Just this week, the Biden administration proposed a new rule intended to protect workers from the effects of extreme heat.
