Current Red Flag Warning remains in effect through Monday morning. * Affected Area...Fire Zone 274 Southern Mono County. * Thunderstorms...Isolated thunderstorms may develop overnight, with faster moving storms producing lightning and limited rainfall. Isolated thunderstorms are possible again Monday afternoon but coverage is expected to be less with storms ending in the evening. * Impacts...Lightning can create new fire starts and may combine with strong outflow winds to cause a fire to rapidly grow in size and intensity before first responders can contain them. * Additional Information...Storms may be a hybrid of wet and dry, but the faster storm motions will likely allow for lightning strikes outside of the main thunderstorm core. With resources already stretched thin, any new fire starts will be an issue. * Outflow Winds...40 to 50 mph wind gusts are possible. PRECAUTIONARY/PREPAREDNESS ACTIONS... Avoid outdoor activities that can cause a spark near dry vegetation, such as yard work, target shooting, or campfires. Follow local fire restrictions.
