California Starts 2026 With Heavy Rain as San Diego and Southern California See Localized Flooding Concerns
CALIFORNIA — Southern California is beginning 2026 under a surge of very heavy rainfall, with radar data showing widespread rain across much of the region and San Diego County and nearby desert areas receiving the highest totals so far, including several locations already exceeding 2 inches of rain since yesterday.
Radar imagery shows persistent bands of moderate to heavy rain moving inland from the Pacific, impacting coastal and inland portions of the state. The most intense rainfall has been focused across Southern California, where precipitation rates have been strong enough to raise concerns for localized flooding, especially in lower-lying and poor-drainage areas.
Heaviest Rain Focused Across Southern California
High-resolution radar scans indicate that the most concentrated rainfall has been occurring across San Diego County, extending inland toward surrounding desert regions. Bright yellow and orange radar returns confirm periods of heavier downpours, particularly near and east of the coast.
While rain has been widespread, the data shows that San Diego and adjacent inland areas have taken the brunt of this system, with rainfall totals climbing rapidly compared to surrounding regions.
Los Angeles Area Seeing Periodic Showers
Farther north, radar imagery across Los Angeles County and nearby inland valleys shows lighter but steady rainfall. While precipitation there has generally been less intense than farther south, repeated showers have continued to move through the area, contributing to wet road conditions and minor ponding in some locations.
The rain coverage remains scattered at times, but additional showers are still possible as the system gradually weakens.
Gradual Drying Trend Emerging
Despite the heavy start to the new year, radar trends suggest that conditions are beginning to slowly dry out, particularly across coastal areas. While a few lingering showers may still develop, the most intense rainfall appears to be shifting away from the region.
This drying trend is especially notable with major outdoor events approaching, as forecast guidance suggests rainfall will not be as widespread moving forward.
What Comes Next
Even as rainfall decreases, saturated ground conditions mean runoff could remain an issue in some locations. Residents across Southern California are urged to remain cautious, especially in areas prone to flooding, rockslides, or poor drainage.
More updates are expected as the weather pattern continues to evolve in the days ahead.
