If you were dreaming of a cozy, rainy Christmas, Southern California is about to overdeliver. A major winter storm fueled by a strong atmospheric river is hitting SoCal just in time for the Christmas holiday, bringing heavy rain, powerful winds, and serious flooding concerns across the region.
According to the National Weather Service, the storm made landfall Tuesday night, continues to intensify through Wednesday and Thursday, with conditions potentially becoming dangerous in some areas.
🌊Flash Flood Warning Today on Christmas Eve
Flash flood warnings continue today for Santa Barbara, Goleta, and Isla Vista, CA. These warnings are valid until Wednesday at noon.
If you are in these areas, move immediately to higher ground. And avoid walking or driving through flood waters at all costs.
💨 Strong Winds & Intense Rainfall
Residents in Los Angeles and Ventura counties should brace for wind gusts between 40 and 60 mph, along with torrential rainfall. By 4 a.m. Wednesday, meteorologists say there’s a 70–80% chance rain rates could hit one inch per hour, which significantly raises the risk of flooding.
Officials are especially concerned about burn scar areas, where mudslides and debris flows could occur quickly. The NWS urges residents in vulnerable zones to sign up for emergency alerts and be ready to evacuate if conditions worsen.
🌊 Flood Watches across Southern California
A flood watch has been issued for much of Southern California, going into effect Tuesday afternoon through Wednesday evening. And this isn’t a quick-moving system. meteorologists expect up to five straight days of precipitation across the region.
By the weekend, rainfall totals could reach:
- 4 to 8 inches across coastal and valley areas
- 8 to 12 inches (or more) in foothills and mountain regions
The National Weather Service’s Oxnard office warned of “copious amounts of rain” paired with “very strong winds at times.”
🎄 One of the Stormiest Christmases in Recent Memory?
Meteorologists are already calling this storm a big one.
“This will easily become the region’s biggest storm of the season,” said Rich Thompson, a meteorologist with the National Weather Service. He added that it could rank among the most impressive Christmas Eve or Christmas Day storms Southern California has seen in years, possibly even breaking records.
Flood watches are now in effect or will be soon for nearly all of California, with Central and Northern California facing elevated risks through Friday.
❄️ What About Snow?
Snow isn’t expected to be a major issue in Southern California’s mountains, though some ski resorts could see fresh powder by Christmas Day.
Meanwhile, the Sierra Nevada is bracing for a much different story – 3 to 5 feet of snow is expected this week, creating major travel disruptions across mountain passes.
⚠️ Stay Safe, L.A.
The NWS urges residents to avoid unnecessary holiday travel, stay alert for flash flood warnings, and take precautions now.
This Christmas could be very wet, very windy, and very intense. Stay dry, L.A. 💙
