AREAS AFFECTED...COASTAL SRN CA...

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 111850Z - 112045Z

BRIEF SEVERE HAIL/WINDS AND EVEN WATERSPOUT/TORNADO THREAT WILL
EXIST THIS AFTERNOON ALONG THE SRN CA COASTAL AREA...BUT THE THREAT
IS EXPECTED TO BE ISOLATED AND WW NOT ANTICIPATED.

COLD TROUGH ALOFT WITH STEEP LAPSE RATES AND STRONG MID/HIGH LEVEL
WINDS ARE RESULTING IN FAVORABLE WIND PROFILES FOR ROTATING STORMS.
STRONGER CONVECTION IS CURRENTLY LOCATED 30-60 MILES OFFSHORE AND
OTHER STORMS SHOULD DEVELOP OFFSHORE THROUGH THE AFTERNOON HOURS.
THESE STORMS LIKELY WILL BE STRONGER OVER THE OCEAN WATERS...WHERE
TEMPERATURES ARE WARMER THAN INLAND...RESULTING IN SLIGHTLY HIGHER
INSTABILITY. HOWEVER...AS THE STORMS MOVE INTO THE COASTAL AREAS...
THE INSTABILITY MAY BE SUFFICIENT FOR HAIL/WIND EVENT AND POSSIBLY A
BRIEF WATERSPOUT/TORNADO. IF A WATERSPOUT/TORNADO DOES DEVELOP NEAR
THE COAST... THEY SHOULD WEAKEN AS THEY MOVE INLAND AND ENCOUNTER A
COOLER BOUNDARY LAYER.
