  • Neighborhoods Devastated by LA Wildfires Now Brace for Deadly Flash Floods

    [ad_1]

    A powerful rainstorm moving down the California coast could dump more than an inch of rain over multiple burn scar areas in Los Angeles County today, including those of the Eaton and Palisades fires. County officials have issued evacuation warnings and orders for these areas due to the risk of flash flooding, mudslides, and debris flows.

    The storm, which started in the Pacific Northwest, brought heavy rain to parts of Southern California late Monday night. National Weather Service forecasters expect it to continue impacting the region through Tuesday. The coasts and valleys could see rainfall totals of up to 1.50 inches (3.8 centimeters), while the foothills and mountains receive up to 4 inches (10 cm).

    The risk of flooding, mudslides, and debris flows is especially high in and below burn scars—areas charred by recent wildfires. In January, the devastating Eaton and Palisades fires consumed nearly 40,000 acres (16,000 hectares) in LA County.

    “As today’s storm intensifies, I cannot emphasize strongly enough the importance of heeding evacuation warnings and orders,” LA County Board of Supervisors Chair Kathryn Barger said in a statement. “These alerts are issued to protect lives. Conditions can change quickly, and once debris flows begin, it may be too late for emergency crews to reach you.”

    How wildfire elevates flood risk

    Burned soil can be as water-repellant as pavement, according to the NWS. As plants burn, they release a waxy substance that melts and solidifies on the top layer of soil, causing it to become hydrophobic. At the same time, fire also burns plant stems and leaves that slow rainwater’s contact with the ground, as well as roots that stabilize the soil.

    As a result, it takes much less rainfall to produce a flash flood, debris flow, or mudslide in a burn scar than in an area unaffected by wildfire. A good rule of thumb is: If you can look uphill from where you are and see a burnt-out area, you are at risk, the NWS states.

    The Eaton fire burn scar stretches some 14,000 acres (5,600 hectares) across Altadena and Pasadena, while the Palisades fire scar encompasses nearly 24,000 acres (9,700 hectares) in and around the Pacific Palisades and Malibu. Other areas that could see significant impacts from today’s storm include the Hawk, Hurst, Kenneth, Sunset, Lidia, Bridge, Canyon, Hughes, and Franklin burn areas, according to LA County.

    Compounding catastrophes

    Officials expect these wildfire-affected areas to experience moderate debris flows and mudflows, with the potential for some streets to become completely blocked by debris. This may also endanger some structures depending on the location and terrain.

    Exactly how this storm will affect communities in burn scar areas remains to be seen, but the risks underscore the lasting impact of wildfire on the landscape and public safety. Californians have become well acquainted with this phenomenon in recent years. Just last week, remnants of Hurricane Priscilla triggered flooding and debris flows in Pine Valley, which was impacted by the Forsyth fire in June.

    As climate change increases the frequency and severity of both wildfires and rainstorms, their compounding impacts will only escalate. This is already straining emergency resources in California and the Pacific Northwest, with no real solution in sight as global temperatures continue to rise.

  • Life-threatening flash floods hit Arizona: Live tracker maps

    [ad_1]

    Meteorologists with the National Weather Service (NWS) have issued a life-threatening flash flood warning for parts of Arizona as remnants of Tropical Storm Priscilla brings excessive moisture to the state.

    Newsweek has reached out to the National Hurricane Center (NHC) by email for comment.

    Why It Matters

    Priscilla was the 16th named storm of the 2025 Eastern Pacific hurricane season. As of a recent update from the NHC, Priscilla had maximum wind speeds of 45 miles per hour, making it a tropical storm, though earlier it was classified as an upper-level Category 2 hurricane, with winds of 110 mph.

    The storm is expected to soon weaken into a post-tropical depression. Despite its weakening power, heavy rain associated with the storm has already stretched as far north as the Desert Southwest.

    What to Know

    NWS offices across the Desert Southwest have issued flood watches in advance of the heavy rain, which is expected to impact parts of California, Nevada, Utah, Colorado, Arizona, and New Mexico through this weekend.

    Although Priscilla has not made landfall and is currently churning off the coast of Baja California, rain bands associated with the storm are already moving into the U.S.

    Priscilla Weather Radar

    Animated weather footage from windy.com shows thunderstorms and heavy rain associated with the storm are now impacting southeastern California and much of Arizona, with the strongest storms in central Arizona.

    Rain Accumulation

    Over the next three days, windy.com shows the worst of the rain will hit Central Arizona near Phoenix, with around 3 to 4 inches possible.

    “Chances for heavy rainfall will increase over the next couple of days, leading to increasing flooding concerns across the area. Greatest rainfall amounts are expected across south-central AZ, especially N and E of PHX,” the NWS office in Phoenix posted on X on Friday. “A Flood Watch is in effect for most areas through Sat.”

    A rainfall forecast from the NWS Weather Prediction Center showed a small portion of north-central Arizona and part of southwestern Colorado could receive rainfall amounts between 4 and 6 inches.

    Lesser amounts of 1 to 2 inches will be much more widespread across Arizona, Utah, and Colorado.

    Thunderstorms

    As of Friday afternoon, the worst of the thunderstorms were clustered near Las Vegas.

    “Tropical moisture brings rainfall chances to most of the area today and tonight,” NWS Las Vegas posted on X. “Precipitation chances decrease and gusty winds increase tomorrow as the system exits.”

    Weather Alerts

    Much of Arizona, Utah, and Colorado faced moderate weather alerts, as well as parts of Southern California and Northwestern New Mexico.

    Most NWS alerts in place were flood related.

    What People Are Saying

    NHC in a public advisory about Priscilla: “As Priscilla moves off the west coast of Baja California, up to an inch of rain is expected across the Baja California peninsula. For the southwestern United States, 2 to 4 inches of rain, with local storm total maxima to 6 inches, are expected across portions of central and northern Arizona, southern Utah, and southwest Colorado through Saturday. Flash flooding is likely in portions of central Arizona and southwest Utah, with scattered areas of flash flooding expected across the remainder of Arizona, southern Utah, southwest Colorado, and far northwest New Mexico.”

    NWS Flagstaff in a flash flood warning currently in place: “Life threatening flash flooding of creeks and streams, normally dry washes, urban areas, highways, streets and underpasses.”

    What Happens Next?

    The flash flood warning will expire at 1:45 p.m. Mountain Standard Time. However, other alerts related to the storm, such as flood watches, will remain in place through Saturday evening.

    NWS and NHC meteorologists will continue issuing updates about the storm as it progresses.

  • Pakistan’s farmers battle floods, debt and climate-driven crisis

    [ad_1]

    Islamabad, Pakistan – As a new wave of cloudbursts, monsoon rains and floods cause havoc across Pakistan, Iqbal Solangi sits in his small house in the southern coastal city of Karachi, feeling the pain of those who lost their loved ones, land and livestock.

    Since late June, a heavier-than-usual monsoon, followed by floods and landslides, has killed more than 800 people, damaged at least 7,225 houses, and washed away over 5,500 livestock in addition to the widespread destruction of crops across the country.

    While the exact cause of the floods is yet to be determined, several factors could have contributed to the deluge, including climate change. Pakistan ranks among the top 10 most climate-vulnerable nations, but it contributes less than 1 percent of global emissions.

    Solangi had ended his climate-change-forced exile from farming in 2022, but ended up losing his rice crop due to the flooding for a third time after the 2010 and 2012 floods, and found himself under a huge pile of debt yet again.

    In 2012, he had moved from a tiny village on the border of the Sindh and Balochistan provinces to Karachi because climate change had made the profession of his forefathers unsustainable. The displacement brought to a temporary end three decades of farming.

    “When my house and land were flooded and I was sitting high up watching it all being washed away, I decided I would never go back to it,” Solangi told Al Jazeera, talking about the 2022 floods, which affected 33 million people and inundated 4 million hectares (9.9 million acres) of agricultural land.

    The Climate Rate Index report in 2025 placed Pakistan at the top of the list of the most affected countries based on 2022 data. Extensive flooding then submerged approximately a third of the country, killed more than 1,700 people, caused $14.8bn worth of damage, as well as $15.2bn of economic losses, and pushed nine million people into poverty.

    In an article in August, Pakistan’s Dawn newspaper wrote: “In today’s Pakistan, the monsoon has transformed from a symbol of beauty and renewal into a harbinger of chaos and despair. What was once awaited with excitement is now approached with dread.”

    Last year, more floods affected thousands, and a heatwave killed almost 600 people. The gradual rise in temperatures is also forcing the melting of the 13,000-plus glaciers in Pakistan, increasing the risk of flooding, damage to infrastructure, loss of life and land, threat to communities, and water scarcity.

    Agriculture remains a key contributor to Pakistan’s economy, contributing approximately 24 percent of its gross domestic product (GDP), according to Pakistan’s Bureau of Statistics (PBS). The livelihood of some 40 million people is also linked with agriculture, which employs more than 37 percent of the labour force.

    In an interview with Al Jazeera earlier this year, Pakistan’s climate change minister warned that the effect of melting glaciers on the river and canal networks “would have catastrophic consequences for Pakistan’s agricultural economy”.

    “These people [working on agriculture] have no economic security, and given our current economic development stage, the government lacks the wherewithal to provide for such a large segment of the population if these gushing floods wash away our infrastructure and devastate agricultural lands. From an economic and agricultural standpoint alone, the potential for devastation is immense,” Musadiq Malik said.

    This year, the agriculture sector has posted a modest growth of 0.6 percent, falling well short of the 2 percent target and significantly below last year’s announced growth of 6.4 percent.

    A recent study published in the Nature journal says the Indus Plain in Pakistan experienced 19 flood disasters between 1950 and 2012, affecting an area of almost 600,000sq km (231,661.3sq miles), causing 11,239 deaths and resulting in economic damage exceeding $39bn. Half of those events took place after 2000.

    Figures shared by PBS show a rise in the number of farmlands across Pakistan over the last few years, from 8.6 million in 2010 to 11.7 million last year, increasing in all provinces bar Punjab. However, changes in rain patterns have also impacted farmers immensely.

    In the northwestern Khyber Pakhtunkhwa province, Basharat Jamal still tills his land but says his crop has almost vanished over the past decade due to droughts.

    Jamal runs a small business to supplement his income but explains that the shift from agricultural practices has landed the region in double jeopardy. The income and produce have reduced significantly, with many farmers moving to urban centres for work. In addition, some farmers now own livestock, which, due to a lack of fodder, destroy their unprotected crops.

    According to the Pakistan Economic Survey 2024-25, major crops, such as wheat and cotton, contracted by 13.5 percent, restricting the overall GDP growth rate by 0.6 percent.

    Farming now is like ‘gambling with nature’

    For Muhammad Hashim, a farmer in Pakistan’s largest province, Balochistan, farming in an unpredictable climate is “like gambling with nature” due to the frequent floods and droughts that have forced him to migrate multiple times.

    He has stuck to farming despite “watching helplessly our crops withering and failing year after year”.

    “Ten years ago, we had no choice but to leave our ancestral land and migrate in search of survival,” said Hashim. “Then came the devastating floods of 2022. Everything we had rebuilt was washed away. Our fields were destroyed again. The next year, we moved again. For a brief time, we found some peace.

    “I worked on my farm and at a shop. Our children were back in school, and life started to feel normal.”

    According to the Migration Policy Institute, more than eight million people were displaced by the 2022 floods, including farmers who gave up on their lands and moved to cities.

    A United Nations Development Programme (UNDP) report on the 2022 floods said: “2022 will be remembered as a critical, trying year for Pakistan, with growing macroeconomic and fiscal concerns, a cost of living crisis impacting the most vulnerable, and cataclysmic floods whose threats were multiplied by climate change.”

    However, soon after, drought forced him to move again, but the “situation is worse than ever”.

    “One year it’s floods, the next it’s drought,” he said, adding that if this pattern continued, his farming days would be over.

  • 1.1M SoCal Homes Face Risk of Flash Flood Damage

    1.1M SoCal Homes Face Risk of Flash Flood Damage

    [ad_1]

    Double-barreled storms across Southern California this month caused hundreds of mudslides — and highlighted an increasing risk of flooded homes.

    One in five residential properties, or 1.1 million houses, condominiums and apartments across six Southland counties, have a moderate or greater risk of suffering damage from flash floods, the Orange County Register reported, citing risk data from CoreLogic.

    It defined flash floods as “when precipitation rates are greater than the speed at which water drains into the ground surface.”

    Overall, 21 percent of local housing face the risk of floods, according to the Register.

    Urban areas like Los Angeles have a high risk of floods because abnormal amounts of rain can’t drain into the soil on streets, parking lots and concrete surfaces.

    Streets can overflow with rain, creating rushing creeks that cause damage. Mountain slopes funnel deluges onto the flats, creating more flooding.

    Weather gurus tell the Register such storms will be more frequent as the region grapples with climate change. Also, property owners should know that typical home insurance policies don’t  cover flood damage, so a separate flood policy is required.

    An average home in Southern California would cost $454,000 to rebuild, assuming a flooded home was a complete loss. That adds up to a $487 billion replacement risk across the region.

    CoreLogic estimates that 28 percent of the 1.1 million Southern California homes facing flash flood risk have an elevated risk of damage. That’s 305,224 homes at greater risk of harm.

    The areas at highest risk include Los Angeles, Riverside and San Bernardino counties, according to the Register.

    In Los Angeles, 420,585 homes are at risk, with 27 percent of those properties in higher danger. In Riverside, 211,418 are at risk, with 39 percent at higher danger. In San Bernardino, 156,987 are at risk, with 31 percent at higher danger.

    Orange, San Diego and Ventura Counties were at far less risk, with around 21 percent of homes in higher danger.

  • Massive Search Underway For Missing Children Swept Away In Suburban Philadelphia Flash Flood

    Massive Search Underway For Missing Children Swept Away In Suburban Philadelphia Flash Flood

    [ad_1]

    WASHINGTON CROSSING, Pa. (AP) — Crews in suburban Philadelphia on Monday intensified the search for a missing 9-month-old boy and his 2-year-old sister, swept away after weekend rains swelled the banks of a creek while they were driving to a barbecue with their family.

    Upper Makefield Township Fire Chief Tim Brewer said Monday the effort would be a “massive undertaking” and that 100 search crew and numerous drones would be looking for the siblings along the creek that drains into the Delaware River in Bucks County, Pennsylvania. The children are members of a Charleston, South Carolina, family that was visiting relatives and friends when they got caught in a flash flood Saturday, Brewer said earlier.

    “As they tried to escape the fierce floodwaters, Dad took his 4-year-old son while the mother and the grandmother grabbed the two additional children,” he said. The father and son were “miraculously” able to get to safety. “However the grandmother, the mother, and the two children were swept away by the floodwaters,” Brewer said. The mother was among those later found dead.

    The grandmother survived, Upper Makefield Police said in a social media post. But the mother of the two children died. Four other people died in the flooding, but it was unclear who they were. Victims’ names have not been released.

    Colleen Courtney, attending a church conference near the search scene Monday, was among those praying for the families.

    “It’s just such a tragedy and just so much grief, I’m sure, and mourning that’s going on right now. I pray to find these children,” said Courtney, of Ewing, New Jersey.

    Another news conference is planned for Monday afternoon.

    An already saturated Northeast began drying out Monday after drenching rain over the weekend resulted in flash flooding in parts of New Hampshire, Massachusetts, Connecticut, New York and New Jersey. New Jersey Gov. Phil Murphy declared a state of emergency Sunday and planned to tour damage early Monday in the northwest part of the state.

    A confirmed tornado touched down Sunday morning in North Brookfield, Massachusetts, but no injuries or major property damage were reported. In New Hampshire, where some roads caved in several towns, heavy rain postponed Sunday’s NASCAR race at the New Hampshire Motor Speedway by a day.

    Vermont reported no immediate safety threats following historic flooding nearly a week ago that dumped up to two months’ worth of rain in two days. U.S. Transportation Secretary Pete Buttigieg planned to visit the state later Monday.

    The Vermont Emergency Management agency reported that swift-water rescue teams conducted an additional six rescues overnight following the storm. The agency also is monitoring areas at risk for landslides due to the rainfall.

    More rain was in the forecast for Tuesday.

    Sunday’s strong storms led to hundreds of flight cancellations at airports in the New York City area, and hundreds were delayed.

    New York Gov. Kathy Hochul said 5 inches (13 centimeters) of rain fell within two hours in Suffolk County on Long Island. The state saw $50 million in damages from storms in the past week.

    In North Carolina, floodwaters were blamed for the death of a 49-year-old woman whose car was swept off a road in Alexander County late Saturday night. A man who was in the car with her was rescued.

    Thousands of people in Kansas and Missouri were without power Monday from weekend storms that swept those states. Kansas’ largest electric power provider, Evergy, said it could take days to restore power to all customers. That could cause hardships for those people, as more storms — and stifling heat — are expected in Kansas and Missouri early this week, according to the National Weather Service.

    The deadly flash flooding in Pennsylvania called to mind the torrential rain that led to at least 25 deaths in New Jersey when the remnants of Ida passed through the state in 2021. People abandoned cars along washed-out roadways as muddy waters overtook driving lanes and flooded low-lying houses then.

    In 2018 in Lancaster County, Pennsylvania, heavy rains brought up to 10 inches (25 centimeters) of water in a short time. No one died in that flooding.

    Associated Press writers Ron Todt in Philadelphia; David Collins in Hartford, Connecticut; Sarah Brumfield in Silver Spring, Maryland; Kathy McCormack in Concord, New Hampshire; Patrick Whittle in Portland, Maine; Margery Beck in Omaha, Nebraska; and Leah Willingham in Charleston, West Virginia contributed to this report.
