|GMZ800 Synopsis For The Coastal Waters From Bonita Beach To Suwannee River- 1013 Am Est Sun Jan 21 2018 |
Synopsis..With surface high pressure to our north, winds will generally be out of the northeast between 5-15 knots before taking an onshore component near the coast in the afternoon due to the development of a weak seabreeze. No headlines are expected over the next few days. Winds will veer to the southeast on Monday and Tuesday ahead of an approaching cold front. Due to cold sea surface temperatures, increasing moisture ahead of the front will create the possibility for sea fog, especially Monday night into Tuesday. Later in the work week, easterly winds will increase to possible cautionary/advisory levels as a north oriented pressure gradient tightens.

806 am est Sun jan 21 2018
Potent short-wave trough moving across north florida this
morning continues to generate a band of showers with
isolated thunderstorms from just offshore pinellas county
northeastward into the atlantic. This trough will be
centered over northeast florida around 10 am or so, then
move into the atlantic by noon. This should bring an end to
the shower activity which will be followed by clearing
The grids were updated about an hour ago to keep showers and
storms lingering through the late morning hours, primarily
north of the tampa bay area. The rest of the forecast is on
track and no major changes are planned.
MainlyVFR but brief MVFR ceilings through 14z can't be
ruled out. Fog may become an issue for Monday after 09z.
Any showers and storms near englewood this morning will be
ending shortly resulting in a mostly pleasant boating day.|
East winds up to 15 knots offshore could result in some chop
early, but winds are expected to gradually diminish this
afternoon. The next hazard for mariners will be the
potential for sea fog, which could begin to impact our
waters late Monday and continue through the day Tuesday. A
cold front will usher in drier air Tuesday night, bringing
an end to the sea fog threat. Enhanced northeast winds
behind the cold front will result in rather choppy
conditions Wednesday and Thursday.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
