A weak upper level low pressure system off the coast of Southern California will bring increasing moisture and instability across the local mountains Saturday through Monday, with the potential for thunderstorms each afternoon. The greatest threat of thunderstorms will be across the mountains of Ventura and Santa Barbara counties. Any storms that develop will have the potential for brief heavy downpours capable of producing localized flash flooding. Other potential thunderstorm threats include gusty winds, small hail, and dangerous cloud to ground lightning which can cause fire ignitions, especially considering the dry fuel moisture levels. People planning outdoor activities across the mountains should closely monitor the weather and be prepared for thunderstorm hazards.
