Thunderstorms Bring Threat of Deadly Floods to Southern California
30 Sep
Summary
- Flash flood warning issued for parts of Los Angeles and Riverside counties
- 1-2 inches of rain already reported, with another 0.5-1 inch expected
- Residents advised to avoid flooded roads, especially in hilly terrain
On September 30, 2025, officials have issued a flash flood warning for portions of Los Angeles and Riverside counties, including areas affected by the recent Bridge Fire. The National Weather Service is urging residents to take precautions as heavy rain and thunderstorms are expected to continue through the evening.
The flash flood warning covers several areas, including Falling Springs, Angeles Crest Highway, and the western sections of the Bridge Fire burn scar. Doppler radar has already detected thunderstorms dropping 1 to 2 inches of rain across the region, with the potential for an additional 0.5 to 1 inch.
Authorities are advising residents to exercise caution and avoid flooded roads, particularly in hilly terrain where low-water crossings can be hazardous. The National Weather Service has emphasized the "turn around, don't drown" warning, noting that most flood-related deaths occur in vehicles. Campers and hikers are also advised to stay away from streams and creeks, which can become dangerous during heavy rainfall.
The threat of flash flooding is being described as "life-threatening," and residents are urged to report any flooding to local authorities and the National Weather Service. Southwestern San Bernardino County and parts of Imperial County are also under flash flood warnings, with several locations expected to experience flooding.
