Onshore winds will persist until a cold front moves offshore tonight,
resulting in a shift to moderate to occasionally strong and gusty north
to northeast winds. Showers and thunderstorms will develop along and
ahead of the front, impacting the bays and coastal waters between later
this afternoon and Sunday morning. A Small Craft Advisory will be in
effect Sunday morning behind the front. Winds will relax by Monday with

southeast winds and seas as the week progresses.
