MOUNTAIN AREA — The National Weather Service (NWS) has issued a Red Flag Warning for this afternoon and evening for the southern Sierra Nevada.
Elevated fire danger is expected due to the possibility of thunderstorms across the Sierra Nevada from Yosemite National Park south to Sequoia National Park. The forecast confidence is low and the Warning has been downgraded from a Watch.
The Red Flag Warning is in effect from 1 p.m. this afternoon to 11 p.m. this evening for dry thunderstorms. Isolated to scattered thunderstorms are expected to develop later this afternoon, providing little rainfall. Winds will be gusty and erratic wherever thunderstorms do develop.
Any fires that develop will likely spread rapidly. Outdoor burning is not recommended.
A Red Flag Warning means that critical fire weather conditions are either occurring now, or will shortly. A combination of strong winds, low relative humidity, and warm temperatures can contribute to extreme fire behavior.
