...THREAT OF STRONG THUNDERSTORMS WITH POTENTIAL FOR LOCALLY
DAMAGING WIND GUSTS...HEAVY DOWNPOURS...SMALL HAIL...AND ISOLATED
WATERSPOUTS TODAY ACROSS SOUTHWEST CALIFORNIA...

A STRONG UPPER LEVEL JET STREAM COMBINED WITH INCREASING
INSTABILITY WILL BRING A CHANCE OF THUNDERSTORMS TODAY ACROSS
SOUTHWEST CALIFORNIA...ESPECIALLY THIS AFTERNOON. THE GREATEST
THREAT OF THUNDERSTORMS WILL BE ACROSS VENTURA AND LOS ANGELES
COUNTIES AS WELL AS THE ADJACENT COASTAL WATERS. SOME OF THESE
THUNDERSTORMS COULD BE STRONG...WITH THE MAIN THREATS BEING
LOCALLY DAMAGING WINDS THAT COULD DOWN TREES AND POWER LINES AS
WELL AS BRIEF HEAVY DOWNPOURS CAUSING LOCALIZED ROADWAY FLOODING.
IN ADDITION...ANY THUNDERSTORM THAT DEVELOPS TODAY WILL BE CAPABLE
OF PRODUCING SMALL HAIL AND DANGEROUS CLOUD TO GROUND
LIGHTNING...INCLUDING BEACH AREAS.

CONDITIONS ARE ALSO FAVORABLE FOR ISOLATED WATERSPOUTS ACROSS
THE COASTAL WATERS...ESPECIALLY SOUTH OF VENTURA. REMEMBER THAT
WATERSPOUTS DO HAVE THE POTENTIAL TO COME ASHORE AS WEAK TORNADOS
ACROSS COASTAL COMMUNITIES. THE THREAT OF STRONG THUNDERSTORMS
IS EXPECTED TO DIMINISH BY TONIGHT.
