... Very strong west to northwest winds and hazardous seas will
continue to affect the coastal waters through tonight...

... Slight chance of thunderstorms across the coastal waters
tonight through Saturday...

An unseasonably strong upper level low over the Great Basin will
slowly move westward into California later today and tonight.
This system will continue to spin across California through
Saturday. Very strong west to northwest flow on the western side
of this system will continue to affect the coastal waters into
tonight.

In the outer waters... gale warnings are in effect through late
tonight for northwest winds of 30 t0 40 kt with occasional gusts
to 45 kt will continue into tonight. In the Santa Barbara
Channel... west to northwest winds of 20 to 30 kt with frequent
gusts to 35 kt will continue into this evening... and gale
warnings remain in effect. Across the inner waters from Point
Mugu to San Mateo Point... small craft advisories are in effect
for west winds of 20 to 25 kt with occasional gusts to 30 kt.

The strong winds will generate dangerous seas as well... with
choppy short-period seas of 15 to 20 feet across the outer
waters... and 6 to 10 feet across the inner waters into tonight.

As the upper low continues to move westward... it will push the
corridor of strongest winds farther off the coast tonight.
Therefore... winds will begin to diminish slowly overnight.
However... with the approach of the upper low... increasing
instability will lead to a threat of thunderstorms across at
least the inner waters tonight through Saturday.

Due to the hazardous nature of the expected wind and sea
conditions... mariners are urged to remain in safe Harbor through
tonight. Monitor NOAA Weather Radio for the latest information...
forecasts... and warnings.
