816 pm est Wed jan 23 2019

Update
Early evening water vapor satellite imagery is showing a
band of convection along and ahead of the cold front quickly
moving from the central gulf of mexico into the eastern
gulf. Breezy southerly winds ahead of the front today have
allowed surface dew points to rise into the 60s across much
of the forecast area, creating an environment favorable for
numerous thunderstorms to roll through the forecast area
overnight.

The forecast looks on track with thunderstorms moving into
the nature coast after midnight, then reaching the tampa bay
area by around day break, with a few strong and damaging
storms possible. The main forecast concern remains the
potential for coastal flooding along the coast of levy and
citrus counties overnight. In addition, the onshore flow
will produce an elevated risk of rip currents along area
beaches. Only minor adjustments were made to the forecast
for the next few hours to keep up with observation trends.

Otherwise, no significant changes are planned for the
evening update.

Aviation
Vfr conditions will start to deteriorate after midnight
tonight with lowering ceilings ahead of an approaching
squall line and cold front. A few showers or storms will be
possible overnight ahead of the front, with the main line of
storms moving through area terminals during the morning
hours. Otherwise, winds will remain gusty through the
period, veering from southerly this evening, to westerly
behind the front Thursday morning.

Marine
Winds are continuing to pick up over the coastal waters
ahead of an approaching cold front, with the small craft
advisory conditions over the offshore waters this evening
expanding towards the coast overnight. In addition to the
strong gradient winds and associated building seas, a line
of thunderstorms will move through the waters tonight and
Thursday morning, creating locally hazardous boating
conditions. High pressure will build in behind the front on
Thursday, allowing conditions to improve through the
weekend.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
