Southern California is experiencing a record-breaking wet winter with heavy storms bringing rain, snow, and flooding risks, but the recent rainfall is helping reduce fire danger and improve drought conditions, though future dry spells could pose risks.
An atmospheric river caused heavy rainfall across San Diego County, breaking several daily rainfall records and leading to flooded streets in La Jolla. The National Weather Service reported historic precipitation levels in various areas, with more scattered rain expected to continue on Sunday. Precipitation totals ranged from 2.00 inches in San Onofre to 0.01 inches in Ocotillo Wells, with some areas experiencing significant rainfall.
San Diego and other areas in Southern California have broken nearly 80-year daily rainfall and temperature records due to a Pacific storm, with nine rainfall records and 16 temperature records broken. The storm is expected to continue bringing moderate to heavy rain, with thunderstorms and a Flood Warning for the San Diego River at Fashion Valley. A Winter Weather Advisory is in place for mountain areas, with around a foot of snow already fallen in some areas.
Severe winter storms fueled by El Niño and atmospheric rivers have set rainfall records in Southern California, with Phoenix expecting weaker systems and less rain due to topography. Despite this, Arizona is still forecasted to receive widespread rain and snow, with the heaviest rainfall expected Tuesday into Wednesday and significant snowfall above 6,500 feet. Excessive runoff may lead to road closures and unsafe recreation, with unsettled weather continuing into Saturday and temperatures dropping from the mid-70s to the lower 60s and upper 50s by Thursday.
An atmospheric river brought heavy rain, flooding, and unseasonably warm temperatures to the Pacific Northwest, causing closures of rail links, schools, and roads. Daily rainfall and temperature records were shattered in Washington state. Rescues were conducted by the Coast Guard in flooded areas, and a man's body was found in a creek. The wet conditions also brought warm temperatures, with some areas experiencing temperatures as warm as parts of Florida and Mexico. The rainfall records for several towns were broken, and significant impacts are expected to continue with rising river levels.
An atmospheric river has brought heavy rain, flooding, and record-breaking warm temperatures to the Pacific Northwest, causing closures of rail links, schools, and roads. Daily rainfall and temperature records were shattered in Washington state, with flood warnings issued in various areas. The small town of Forks, known as the rainiest town in the contiguous U.S., saw its rainfall record more than double. Seattle also set a new rainfall record for the date. The wet conditions have caused significant impacts, including river crests and rises, and closures of highways and trails. Officials have urged caution and advised drivers to expect delays.
Storm Hilary, now a post-tropical cyclone, has brought historic rainfall, flooding, and mudslides to Los Angeles, breaking "virtually all" of the city's daily rainfall records. The storm made landfall along Mexico's Baja California Peninsula and moved through Tijuana, threatening improvised homes on the hillsides south of the U.S. border. Hilary is the first tropical storm to hit Southern California in 84 years and has caused power outages, flooded roadways, and downed trees. The National Hurricane Center expects "life-threatening and locally catastrophic flooding" in parts of the southwestern U.S., with additional rainfall expected. Coastal warnings have been discontinued, and the storm is expected to dissipate later in the day.
Berks County in Pennsylvania is experiencing flash flooding and severe storms, with watches and warnings in place. Some areas have already received over 4.78 inches of rain, potentially breaking a date record from 1952. Power outages have been reported, and the unsettled weather is expected to continue into Monday. Despite the heavy rainfall, the region is gradually erasing its deficit in precipitation, as it was previously under a drought watch.
