Red Flag Warning Issued for Northern and Southern Sierra Front Until 10 PM Tonight
A Severe Red Flag Warning is in effect for Northern and Southern Sierra Front areas until 10 PM tonight, urging residents to avoid spark-producing outdoor activities due to high winds and low humidity.
Residents in the Northern and Southern Sierra Front areas are advised to avoid outdoor activities that could cause sparks due to a Severe Red Flag Warning issued by the National Weather Service (NWS) Reno, NV.
The warning is in effect from 9:58 AM PDT today, September 25, 2026, until 10:00 PM PDT tonight, September 25, 2026. This affects Fire Weather Zone 420, encompassing Carson City, Douglas, Storey, Southern Washoe, Western Lyon, and Far Southern Lassen Counties. Fire Weather Zone 421, including Alpine, Northern Mono, Southern Lyon, and Western Mineral Counties, is also under this warning.
Southwest to west winds are expected to reach 20 to 30 mph, with gusts up to 45 mph. Humidity levels could drop as low as 17 percent this afternoon, lasting for 4 to 7 hours. The NWS warns that these conditions can cause fires to grow rapidly in size and intensity, making them difficult for first responders to contain.
