California — Rain-slick streets, swaying palms, and darkening skies signal a dangerous shift across Southern California this morning. What begins as steady rainfall quickly escalates into a multi-day threat, just as Christmas travel approaches.
According to the National Weather Service in Los Angeles/Oxnard, a Flood Watch remains in effect through Thursday evening for Los Angeles, Ventura, Santa Barbara, and San Luis Obispo counties. Widespread rain develops through the day, intensifying into heavy downpours Wednesday with rainfall rates capable of overwhelming roads, creeks, and drainage systems.
This storm taps into a strong atmospheric river. Several inches of rain are possible in coastal and valley areas, with higher totals near foothills and recent burn scars. Urban flooding becomes likely, especially along surface streets, underpasses, and flood-prone corridors. Rapid rises in creeks and small rivers are expected.
Travel impacts could escalate fast. Portions of I-5, U.S. 101, I-10, and I-405 may see standing water during heavier rain bands. Mud and debris flows remain a concern near canyon roads and mountain passes. Drivers should avoid flooded roadways and plan alternate routes.
Compounding the threat, a Wind Advisory remains in effect through Thursday afternoon. Southeast winds of 25 to 35 mph, with gusts up to 55 mph, may down trees and power lines. High-profile vehicles face difficult driving conditions, particularly on exposed freeways and coastal routes.
Rain continues through Christmas Day with little break. By Friday, showers linger with warmer temperatures near 60 degrees. While rain intensity eases, saturated ground keeps flooding concerns elevated for post-Christmas travelers.
Residents should secure loose items, charge devices, and monitor alerts closely. Conditions may deteriorate quickly during heavier rain bursts.
