Southern California is facing a wet and hazardous start to 2026 as a powerful storm system moves through the region, bringing heavy rain, flooding concerns, and evacuation warnings across multiple counties.
The storm is expected to impact Los Angeles, Orange, Riverside, San Bernardino, and Ventura counties, affecting more than 17 million residents as saturated ground raises the risk of flash flooding and debris flows.
Flood Watch and Evacuation Warnings Across SoCal
A Flood Watch is in effect from Wednesday night through Thursday evening, covering much of Southern California. Officials warn that rainfall totals of 1 to 3 inches, with locally higher amounts in mountain areas, could lead to dangerous conditions.
Evacuation warnings have been issued for Los Angeles burn scar areas, including regions affected by recent wildfires. Authorities urge residents in these zones to prepare for possible evacuation if heavy rain triggers mudslides or debris flows.
Storm Timeline: When Will the Heaviest Rain Hit?
Meteorologists expect:
- Light showers early, increasing throughout New Year’s Eve
- Heaviest rainfall from Wednesday night into New Year’s Day
- Periods of intense downpours capable of causing street flooding and debris movement
- A brief lull later Thursday into Friday, with additional rain chances lingering into the weekend
Mountain areas may see up to 5 inches of rain, significantly increasing landslide risk.
Emergency Response and Road Closures
Los Angeles County has declared a local state of emergency following consecutive storms in late December. The declaration allows faster recovery efforts and access to disaster funding.
As a precaution:
- Topanga Canyon Boulevard (State Route 27) has been closed due to debris flow concerns
- Crews remain on standby along Pacific Coast Highway (PCH) and other vulnerable roadways
- First responders are urging residents to avoid unnecessary travel, especially during overnight hours
Rose Parade and New Year’s Events Continue Despite Rain
Despite the storm, the Rose Parade in Pasadena will proceed as scheduled on New Year’s Day. Organizers and attendees are preparing for wet conditions, marking one of the rare occasions rain affects the iconic event.
Spectators are advised to:
- Wear rain jackets or ponchos instead of umbrellas
- Expect reduced crowds due to weather
- Plan extra travel time due to slick roads
Storm Impact on Communities and Recovery Efforts
In mountainous and rural areas, volunteers continue cleanup efforts from previous storms that caused flooding and mud damage to homes. Emergency teams warn that already-saturated soil makes the region especially vulnerable to renewed rainfall.
Officials emphasize staying informed and following all safety advisories.
Safety Tips During the Southern California Storm
