Light onshore winds will prevail tonight. Winds should strengthen
Monday ahead of the next cold front that is forecast to move into
the coastal waters around midweek. Water temperatures have also 
cooled with the recent cold weather, and some patchy sea fog can 
be expected as the onshore flow ushers more humid air into the 
area as early as tonight. The cold front will bring a chance of 
showers and thunderstorms Tuesday night through Wednesday 
afternoon.
