...SHOWERS AND A SLIGHT CHANCE OF THUNDERSTORMS LATE TONIGHT
THROUGH WEDNESDAY EVENING...

A mid to upper level low pressure system off the Central Coast
will steadily move northeastward through Wednesday evening. The
low is interacting with a tropical origin air mass resulting in
showers and thunderstorms. Since the low is forecast to move
northeastward expect showers and a slight chance of thunderstorms
to move with it over much of our coastal waters including the bays
late tonight through Wednesday evening. Thunderstorms may produce
strong and gusty outflow winds, locally rough seas and briefly
heavy rain.
