Heavy rains trigger flash flooding across Southern California
Severe winter weather swept across Southern California this week as intense rainfall caused flash flooding, mud flows and dangerous travel conditions, prompting authorities to issue evacuation orders and road closures in several areas.
The storm system, driven by a powerful atmospheric river carrying moisture from the Pacific Ocean, brought torrential downpours to the Los Angeles region and surrounding counties. In mountainous communities east of Los Angeles, emergency services responded to numerous rescue calls involving stranded motorists and flooded roads. No fatalities were reported, according to local officials.
In some areas, rainfall exceeded one inch per hour, overwhelming drainage systems and sending mud and debris through residential neighborhoods, particularly in zones previously affected by wildfires. Authorities warned that burned terrain remains highly vulnerable to landslides during heavy rain events.
Weather officials cautioned residents against unnecessary travel and urged those living in high-risk zones to follow evacuation or shelter-in-place instructions. Several highways, including major mountain routes, were temporarily closed due to flooding, fallen debris and hazardous driving conditions.
Forecasters warned that the storm could continue through the holiday period, with additional rainfall and strong winds expected. Higher elevations were also forecast to receive significant snowfall, further complicating travel across the state.
