Mapping released by the National Weather Service in Eureka indicates low relative humidity and gusty winds are converging to create “critical fire weather” for areas of northern California. The warning goes into effect this evening at 11:00 and runs till tomorrow night at 8:00.
The area of the Red Flag Warning covers northeastern Mendocino County, southeastern Trinity County, the entirety of Lake County, and runs eastward affecting multiple counties in the Central Valley.

The National Weather Services predicts that northwind gusts from 25 to 35 miles per hour will rake across high terrain and exposed ridges in the region. The region’s relative humidity will fall into the teens on Wednesday afternoon making for conditions in which any fires that sparky will potentially “spread rapidly.”
Pacific Gas and Electric’s Public Safety Power Shutoff Forecaster has identified Colusa, Glenn, Shasta, Tehama, Lake, Napa, Yolo, and Butte Counties as locations that might experience power outages as a result of the weather.
