FOR IMMEDIATE RELEASE
Los Angeles, CA – Beginning Wednesday, August 20, through Sunday, August 24, 2025, an extended period of hot weather combined with a high risk for wildfires is expected in portions of Los Angeles County, with highs in the 90s to lower 100s, away from the coast. Specific areas of concern for heat risk include the Santa Clarita and Antelope Valleys, portions of the San Gabriel Valley, the LA Basin, and the 101 corridor out to Westlake Village.
Red flag warnings will be posted for the Santa Clarita and Antelope Valleys, along with the Angeles National Forest. There is also a chance of thunderstorms from Friday through Sunday and into next week, which can generate lightning strikes and trigger wildfires and localized flash flooding with mud and debris flows in recent burn scar areas.
In preparation, the County of Los Angeles Fire Department (LACoFD) has implemented its augmented staffing plan by ordering additional staffing and pre‑deployment of ground and aerial resources throughout Los Angeles County. The LACoFD advises residents to take care of themselves and others who are most vulnerable as well as take appropriate precautions, if they live in wildfire-prone areas or communities prone to flooding, especially in recent burn areas.
Residents are reminded to:
-
Sign-up for emergency alerts at alert.lacounty.gov.

If you see something, say something. Report any sign of smoke or fire immediately to your local fire department by dialing 9-1-1. If you dial 9-1-1 from your cell phone, be sure to know your location.
