Just a few minutes of intense rain can start a debris flow. The National Weather Service will issue a flash flood watch or warning for your area when rainfall is anticipated to be intense."
An atmospheric river is expected to bring rain, heavy at times, to Southern California beginning Thursday night through the weekend. Downtown Los Angeles could receive about 2.62 inches of rain from Friday morning through Sunday under the most likely scenario. Evacuation warnings run from 6 p.m. Thursday to 11 a.m. Sunday for areas near recent burn scars, including zones affected by the Palisades, Eaton, Kenneth, Sunset and Hurst fires. Topanga Canyon Boulevard between Pacific Coast Highway and Grand View Drive will close at 10 p.m. Thursday with possible extended closure. Forecast confidence is good for Thursday/Thursday night but low for Friday–Sunday due to model uncertainty from a closed low. Intense rainfall—about half an inch per hour—on recently burned slopes can trigger debris flows within minutes, and flash flood watches or warnings will be issued where intense mountain rainfall is expected. Debris flows can hit new or previously affected areas and can vary in size and speed.
