A powerful winter storm has brought treacherous conditions to California, impacting areas from Sonoma County to the Sierra Nevada. Millions of Los Angeles County residents were under flash flood warnings, and evacuation warnings were issued for communities previously scarred by wildfires due to the risk of mud and debris flows. The storm caused significant disruptions to travel, with road closures and dangerous driving conditions reported across the state.

Why it matters

The combination of recent wildfires and heavy rainfall creates a particularly dangerous scenario, as burned areas are more susceptible to mud and debris flows. Preparedness and rapid response are critical in mitigating the potential for further damage and ensuring public safety.

The details

The storm caused significant disruptions to travel, with traffic temporarily halted on Interstate 80 near the Nevada state line due to spinouts and crashes, and a fallen tree blocking southbound lanes of US-101 in Santa Barbara County. Forecasters predict up to 8 feet (2.4 meters) of snow could accumulate in the western slope of the Sierra Nevada, northern Shasta County, and parts of the state's Coast Range through late Wednesday, making travel conditions dangerous.

  • The storm arrived in California on Monday, February 16, 2026.
  • Forecasters predict the heavy snow, wind, and low visibility will continue through late Wednesday, February 18, 2026.
