Rainfall in Southern California Reduces Fire Risk Amid El Niño Conditions
US · Published Oct 22, 2026
• Southern California has experienced a series of El Niño-driven storms, bringing significant rainfall to regions like the Inland Empire, San Diego, and Orange counties.
• These areas received 1 to 3 inches of rain from Tropical Storm Rachel earlier this month, with additional rainfall this week.

Impact & Risks

The rainfall has alleviated fire risks in many areas, but regions with minimal precipitation, such as Los Angeles and Ventura counties, remain vulnerable. Light vegetation in these areas could still become fire-prone under dry and windy conditions, particularly during Santa Ana wind events. Additionally, the increased rainfall raises concerns about flooding and debris flows in burn scar areas, where hydrophobic soils may repel water, leading to runoff and potential hazards. Local authorities are preparing for these risks by reinforcing vulnerable areas and clearing drainage systems.
