Update
Latest visible satellite images and observations show an area of
dense fog extending across tampa bay and over pinellas county. Some
additional fog remains across other areas, but is starting to lift.

This area of dense fog has been the problem of the day so far, but it
is shifting westward and should continue to do so over the next hour
or so, with improving conditions. The rest of the day will be warmer
and dry. A southeast low-level flow is forecast to turn onshore as a
sea breeze circulation develops, and this will keep coastal areas a
bit cooler while the rest of the area warms into the lower 80s. The
forecast remains on track with no update needed outside of the fog.

Aviation
Vfr conditions have returned to several terminals, though ktpa, kpie,
and kpgd are still reporting lifr conditions. Expect the low clouds
and fog at kpgd and ktpa to scatter out over the next hour or two.

Kpie will likely take a bit longer to goVFR, but should by noon. A
period ofVFR can be expected for all sites this afternoon, but then
this evening and tonight, rain chances increase and sea fog will
likely become an issue.

Marine
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.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
