SYNOPSIS FOR THE COASTAL WATERS FROM BONITA BEACH TO SUWANNEE RIVER-
1014 AM EST Mon Jan 22 2018

.SYNOPSIS...Southeast low-level flow will shift southward tonight
ahead of an approaching cold front. Expect areas of showers and
isolated thunderstorms tonight into early Tuesday ahead of this
boundary, with the greatest coverage expected from Tampa Bay
northward. Winds will become north to northeast late Tuesday into
Wednesday behind the front, with speeds increasing to cautionary
levels at times.

A Dense Fog Advisory remains in effect for Tampa Bay and the near
shore Gulf waters from Englewood to Tarpon Springs until 11 am. The
fog is slowly shifting westward and should continue to do so, but
this advisory may be extended if sea fog lingers. The greatest
potential for sea fog through the rest of the day will be offshore of
the Nature Coast, with this potential expanding southward tonight
into Tuesday morning. Sea fog will end from north to south Tuesday
afternoon and evening with the passage of the cold front.
