Southern California is bracing for a series of storms this week, bringing much-needed rain but also potential hazards, especially for areas recently affected by wildfires. The first storm is expected to arrive on Monday evening, with a 70% chance of light showers on Tuesday. Winds are also anticipated, particularly south of Point Conception.
The real concern begins early Wednesday, when a powerful atmospheric river is set to hit the region. This storm is predicted to deliver heavy rainfall along the coast and into the mountains, lasting through Thursday. Meteorologist Robbie Munroe from the National Weather Service noted that almost every area will experience moderate to heavy rain, with some spots possibly seeing isolated heavier showers.
Rainfall totals are expected to range from 1 to 2 inches in the valleys and 2 to 4 inches in higher elevations. A flood watch is likely to be issued from 6 p.m. Wednesday to 6 p.m. Thursday. Areas with recent burn scars are particularly vulnerable, as they could face flash flooding, debris flows, and mudslides.
Local officials are preparing for the worst. Mark Pestrella, director of Los Angeles County Public Works, expressed confidence in their ability to manage debris flows resulting from the anticipated rain. The county is also coordinating with law enforcement and fire departments to plan for possible evacuations in areas without adequate debris basins, especially in vulnerable communities like Pacific Palisades, Altadena, and Malibu.
Coastal and valley communities can expect 1 to 2 inches of rain, with a chance of thunderstorms that may lead to significant roadway flooding. Wind gusts could reach 30 to 50 mph, posing risks of downed branches and power outages. Residents are advised to stay indoors during outages, avoid using candles, and keep their refrigerators closed to preserve food.
In the mountains, rainfall is expected to be heavier, with 2 to 4 inches possible. This could lead to hazardous travel conditions due to flooding and snow. Snow levels are predicted to drop to 2,500 feet by Thursday, with heavy snow forecasted in the San Bernardino and Riverside County mountains.
Travelers should be cautious, especially on highways like the 5 Freeway near Tejon Pass and Highway 14 through the Antelope Valley. Authorities recommend checking road conditions and being prepared for delays.
As the storms approach, residents are reminded to stay informed and take necessary precautions to ensure their safety.
