Strong Winds Impact Santa Barbara, Ventura, SLO Counties as Holiday Storm Intensifies

Southern California’s Central Coast is bracing for a major holiday storm as a powerful atmospheric river moves into Santa Barbara, Ventura, and San Luis Obispo counties, bringing the threat of heavy rain, strong winds, flooding, and dangerous coastal conditions.

Santa Barbara, Ventura, and San Luis Obispo counties are under multiple weather alerts, with officials urging residents to remain alert as harsh weather conditions are expected to persist through the end of the week.

The National Weather Service (NWS) said a powerful stream of moisture is expected to bring heavy rainfall across Southern California. The Weather Prediction Center has issued a Level 4 of 4 high risk for excessive rainfall through Thursday morning, warning of severe and widespread flash flooding.

Flooding could occur even in areas that rarely experience such impacts, posing a serious threat to lives and property. Rain is also forecast to continue on Christmas Day, with a moderate risk of excessive rainfall in effect from Thursday into early Friday.

The NWS has issued a flood advisory for parts of Santa Barbara and Ventura counties through Wednesday morning, with rainfall totals of up to two inches. Low-lying neighborhoods and poor drainage areas may see minor flooding, including water flowing over roadways. Additional flood advisories remain in effect for Ventura County through Wednesday afternoon.

A flood watch is also in effect through Friday afternoon for larger portions of Southern California. Forecasters warned the storm system could trigger widespread flooding, rapid rises in creeks and rivers, and an increased risk of rockslides and mudslides.

Travel disruptions are likely during the busy holiday travel period due to the storm system.

The NWS has also issued a high wind warning through Thursday afternoon for San Luis Obispo, Santa Barbara, and Ventura counties. Sustained winds of 30 to 50 miles per hour are expected, with gusts reaching up to 70 miles per hour or higher in mountain areas.

12/23/25: SLO Co is under multiple weather related watches and warnings related to the incoming storm.

Officials warn that strong winds combined with saturated soil increase the risk of falling trees, downed power lines, and power outages.

Coastal areas are also facing hazardous conditions, with high surf advisories in effect through Saturday morning for beaches across San Luis Obispo, Santa Barbara, and Ventura counties. Waves of 6 to 16 feet are expected, along with dangerous rip currents.

The Christmas storm is driven by an atmospheric river, which is a long, narrow band of moisture in the atmosphere that transports large amounts of water vapor from the tropics toward land and can release intense rainfall over short periods.

While atmospheric rivers can help replenish water supplies in drought-prone areas, they can also lead to flooding, debris flows, and hazardous travel conditions.

Storm Preparedness in Santa Barbara, Ventura and SLO Counties

In response to the storm, the City of Santa Barbara has activated emergency storm parking for residents. Eligible residents must register their vehicles through the city’s storm parking portal during the activation period. Parking fees will be waived for registered vehicles, but standard rates will apply once the activation period ends.

🚨Major storm expected. Be prepared for possible flooding in low-lying areas, damaging winds and downed trees/ power outages.
✅Remain vigilant as conditions can change quickly.

In coastal areas, people are asked to stay out of the water and away from rocks and jetties due to dangerous surf conditions. Residents in hilly or burn scar areas should remain alert for signs of debris flows and be prepared to act if conditions worsen.

Authorities continue to monitor the storm and urge the public to stay informed through official weather updates as Southern California faces this powerful holiday weather system.
