Southern California is preparing for a series of storms expected to bring significant rainfall, colder temperatures, and mountain snow beginning Sunday. The National Weather Service warns of potential flooding, mudslides, and hazardous travel conditions throughout the week, with the most intense weather anticipated early in the week. Residents are urged to take precautions as a powerful weather system moves into the region.
The first storm, expected to be the strongest of the three, is forecast to deliver 1 to 3 inches of rain in coastal and valley areas, and 2 to 5 inches in the mountains by late Monday, according to the National Weather Service. A Flood Watch has been issued for a large portion of Los Angeles County, effective from Monday morning through Monday evening, highlighting the increased risk of dangerous conditions.
Storm Timeline and Expected Impacts
Rainfall intensity is expected to decrease Monday night into Tuesday, but scattered showers may persist as colder air settles in. Snow levels will initially be around 6,500 feet, dropping to near 5,000 feet by Tuesday, potentially impacting travel through mountain passes. A second storm system is predicted to arrive Tuesday night into Wednesday, bringing additional rain and snow, with snow levels potentially falling as low as 2,500 to 3,000 feet. This could create significant hazards for drivers in higher elevations.
Meteorologists anticipate an additional 1.5 to 3 inches of rain on Tuesday and Wednesday, with the possibility of 3 to 6 inches in the mountains. Temperatures will plummet, with daytime highs in the mid-50s across most of Los Angeles and Orange County throughout the week. Inland areas, including the Santa Clarita and Antelope valleys, will experience even colder temperatures, dropping into the low 50s and upper 40s. Overnight lows are expected to be in the 40s, falling into the 30s in the mountains, Santa Clarita Valley, and the high desert from Tuesday through Friday.
The combination of thunderstorms, strong winds, and rough seas could create dangerous marine conditions early next week. A third storm system is anticipated on Thursday, though the amount of moisture remains uncertain.
Preparedness and Safety Measures
Authorities are advising residents in areas prone to flooding to be prepared to take action. The National Weather Service warns of the potential for rock and mudslides near steep terrain and debris flows in burn scar areas. It’s crucial to stay informed about changing conditions and heed any evacuation orders issued by local officials.
Current conditions in Los Angeles Downtown show a temperature of 52°F (11°C) with 92% humidity and north-northwest winds at 2 mph, as of 3:25 AM PST on February 15, 2026, according to the National Weather Service. Detailed forecasts are available online.
Looking Ahead
As the week progresses, residents should monitor forecasts closely for updates on storm intensity and potential hazards.
