Over the weekend, a severe rainstorm hit California, triggering flood and mudslide warnings in various areas. Particularly in the fire-stricken areas of Los Angeles, tens of thousands of households were forced to evacuate urgently. By Sunday afternoon, though evacuation warnings and orders were temporarily lifted, the weather bureau predicted that a new storm could hit on Monday, potentially bringing more rainfall.
On the Saturday just passed, heavy rains blanketed multiple counties in Greater Los Angeles. Major highways leading to downtown LA were congested, with some roads closed off. Trees were toppled, power lines were downed, and some residential areas in the city experienced power outages. Small craft advisories were issued for coastal waters.
The latest rainfall data from the National Weather Service showed that over the past 48 hours, the widespread rainfall in five counties in the Greater Los Angeles area – Los Angeles, Ventura, Orange, San Bernardino, and Riverside – ranged from 2 to 5 inches.
After a day of heavy rain, Southern California slightly escaped the influence of the strong atmospheric river on Sunday. However, another rotating low-pressure system is moving towards the region, expected to bring thunderstorms and weak tornadoes on Monday. Rainfall rates could reach half an inch per hour, enough to cause minor flooding in low-lying or poorly drained areas.
Officials are reminding everyone to drive safely, slow down, and stay vigilant about the weather conditions, preparing for storm safety measures.
Due to the rainstorm posing a threat of mudslides in the areas affected by the Palisades and Eaton fires, LA County officials issued evacuation orders, evacuation warnings, and flood alerts for high-risk areas. As of 5 p.m. on Sunday, all alerts were lifted, and no evacuation warnings or orders have been issued for the upcoming storm.
The Los Angeles Fire Department continues to urge residents to prepare for storm safety before heavy rainfall hits: ensure house gutters, roofs, and downspouts are clean and clear; have sandbags, plywood, plastic sheeting, lumber, hand tools, and other materials ready to address sudden water issues. All fire department stations also provide free pre-filled sandbags.
LA County Sheriff’s deputies further advise Los Angeles residents to dial 911 in case of life-threatening situations, not attempt to cross flood areas, walk or drive through moving water, or enter flowing water bodies. If anyone is swept into a rushing water body, do not enter the water for rescue attempts but immediately dial 911.
Meteorologist Joe Sirard from the National Weather Service stated that if rainfall continues as expected until Tuesday, it could become the wettest November in the Los Angeles area since 1985.
With the rain, temperatures are also dropping suddenly, resulting in snowfall above 6,500 feet in elevation. The National Weather Service indicates that as the next wave of cold air arrives, snowfall amounts may increase, possibly continuing in the Big Bear Lake area until Wednesday morning.
Some roads near mountains and valleys are muddy and slippery, with vehicles traversing certain mountainous areas potentially requiring the installation of tire chains. Caltrans recommends that residents heading to mountainous regions should prepare blankets, flashlights, chargers, and emergency supplies.
