...DENSE FOG TO AFFECT MOST OF THE COASTAL WATERS...

A southerly surge of stratus from coastal waters South of Point
Conception moving north around Point Conception and will continue
to surge northward allowing dense fog to move north across the
Central Coast as well as coastal waters to the south through this
afternoon.

Mariners should be prepared for abrupt visibility changes down to
one nautical mile or less. Reduce speeds and be on the lookout
for exposed rocks and other vessels, including large ships in the
shipping lanes. Use radar or GPS navigation if available, and
consider remaining in harbor if such equipment is unavailable.

There is the slightest chance for a thunderstorm to develop above
the widespread stratus across the inner waters from Point Mugu to
San Mateo Point through this morning.
