The National Weather Service has issued a red flag warning for parts of northeastern California and northwestern Nevada.
The agency says scattered wet and dry thunderstorms plus winds of up to 50 or 60 miles per hour create conditions in which fires can start and spread quickly.
CAL FIRE says residents of these areas should avoid activities that can cause sparks near dry vegetation, such as mowing or trimming dry grass, and make sure trailer chains do not drag on the road. More recommendations and an area map of the red flag area can be found here.
CAL FIRE currently has nearly 7,000 firefighters battling eight large wildfires throughout the state.
