Southern California is bracing for its strongest storm in over a year, with meteorologists warning of potential flooding and landslides, particularly in areas affected by recent wildfires. The storm, fueled by an atmospheric river, is expected to bring heavy rainfall starting Wednesday, with the most intense conditions anticipated on Thursday.
Forecasters predict that downtown Los Angeles could receive over two inches of rain by Friday, with some regions, particularly mountainous areas, facing even higher totals. Rainfall amounts in Los Angeles, Ventura, and Santa Barbara counties are expected to range from 1.5 to 3 inches, while San Luis Obispo County may see between 3 to 5 inches, with local mountains receiving up to 10 inches.
The National Weather Service has advised residents to avoid travel on Thursday due to hazardous conditions, including slick roads and the likelihood of accidents. Meteorologist Ryan Kittell emphasized the dangers, stating, “Thursday is just not a great day to be on the road.” He cautioned that residents near burn scars should either evacuate before the storm or remain indoors, as the risk of debris flows and flash flooding is significant.
In addition to the rainfall, strong winds are expected, with gusts reaching up to 60 mph in mountainous regions. These winds could lead to downed trees and power lines, exacerbating the storm’s impact. In urban areas, the potential for localized flooding on roadways, including freeways, is high, and swift-water rescues may be necessary for those trapped by rising waters.
The storm is particularly concerning given the dry conditions Southern California has experienced this winter, which followed a devastating fire season. The lack of vegetation in many areas increases the risk of mudslides when heavy rain falls. Experts note that the threshold for debris flows is often reached when rain falls at a rate of half an inch per hour, a possibility during this storm.
Residents are urged to prepare for possible power outages and to stay informed about weather updates. The storm is projected to move out of the area by Friday, with a return to dry weather expected in the following days. While this storm may bring much-needed moisture to the region, it also poses significant risks that residents must take seriously.
