GMZ800 Synopsis For The Coastal Waters From Bonita Beach To Suwannee River- 931 Am Edt Thu Apr 27 2017
Synopsis..High pressure centered over the atlantic will continue to ridge west across southern florida through the weekend. This will keep southeast to south winds in place with a shift to southwest near the coast each afternoon as the sea breeze develops. A weak front washing out over the northern gulf today will produce a tight pressure gradient, with cautionary headlines needed for the gulf waters north of tarpon springs today. Winds will increase again to around exercise caution levels Sunday and Monday as another front moves into the region.

Update
Morning observations and latest visible satellite imagery is
continuing to show a stratus cloud deck from tampa bay southward,
primarily along the coastal counties. These clouds and fog/mist is
expected to burn off in the next couple of hours giving way to sunny
skies. High pressure continues to ridge across the state and will
produce a southerly component wind which will help to pump moist and
warm air over the region. Daytime highs today will approach record
levels with upper 80's to low 90's expected region wide. Will update
sky grids to account for cloud cover south of tampa bay along the
coastal counties. No other changes needed at this time.

Aviation
Patchy fog/mist and low stratus continues for the southern terminals
(srq/pgd/fmy/rsw), so will keep tempo vsby and cig restrictions
through 15z. Conditions are expected to improve toVFR after 15z and
will remain so for the rest of the period. Predominant wind flow
will be out of the southeast, then becoming onshore as the sea
breeze sets up this afternoon. No other aviation impacts expected.

Marine
High pressure will continue to ridge from the atlantic into the
eastern gulf of mexico through the weekend. A weak front washing out
over the northern gulf today will produce a tight pressure gradient,
with cautionary headlines needed for the gulf waters north of tarpon
springs this morning. Winds will increase again to around exercise
caution levels Sunday and Monday as another front moves into the
region.

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.
