Los Angeles, California – Southern California is currently under a rare Level 4 of 4 risk of excessive rainfall, affecting more than 14 million people. The prolonged downpours have resulted in submerged roadways and damaging debris flows, with the potential for mudslides and life-threatening flooding. Following a recent period of record rainfall, the state is now facing the consequences of an intense, long-lasting atmospheric river that is drenching the region.
A firehose of rain is expected to persist over Southern California, exacerbating the high risk of flooding throughout Monday, particularly in Orange County. Winds reaching 98 mph have caused power outages for over 600,000 customers, with wind gusts near 60 mph at the San Francisco International Airport. Additional rainfall totals of 3 to 6 inches are forecasted, equivalent to more than a month’s worth of rain in just several days.
The Weather Prediction Center has issued a rare high risk of excessive rainfall – a Level 4 of 4 – for more than 14 million people across Southern California on Monday, including downtown Los Angeles, Anaheim, and Long Beach. The extended period of relentless downpours has led to an “extremely dangerous situation” in several areas, with damaging landslides, flooded roadways, and submerged vehicles being reported.
As a result of the heightened flood risk, several residents in Santa Barbara, San José, Los Angeles, and Ventura County have been under evacuation orders. Several school districts in Santa Barbara County have canceled classes, and some have transitioned to remote learning. California Governor Gavin Newsom has declared a state of emergency for multiple counties in preparation for the storm’s effects.
The storm is expected to stall as it moves onshore, bringing a longer duration of rain compared to the previous storm that impacted the state. The heightened flood risk is anticipated to continue through Tuesday, with residents being urged to stay off the roads and remain at home if possible. The storm has also resulted in significant and unusual amounts of rainfall, with some areas expecting up to 8 inches of rain.
In addition to life-threatening floods and landslides, the storm has caused significant damage in various neighborhoods. Low-lying and flood-prone areas, as well as residents in San Bernardino County, have experienced critical situations due to rapidly rising river levels and flooded roadways. Multiple homes have been impacted by debris flows, and some residents have been rescued after becoming stranded in flood waters.
Overall, the rare and prolonged period of relentless rainfall and strong winds have significantly impacted Southern California, prompting widespread power outages, evacuations, and cautionary measures to ensure the safety of residents. As the state continues to grapple with the effects of the storm, authorities are closely monitoring the situation and providing necessary assistance to affected areas.
