GMZ800 Synopsis For The Coastal Waters From Bonita Beach To Suwannee River- 827 Pm Est Sat Nov 18 2017
Synopsis.. Atlantic high pressure across florida to the gulf of mexico slides southward through tonight then exits east Sunday as a cold front moves into northern florida. The front tracks down the state during Sunday and slips south of the florida keys early Monday. High pressure behind the front builds in across the gulf region and treks east to the atlantic by midweek...allowing the front to lift north from the keys. A low pressure area may form on the front toward the end of the week...introducing some uncertainty into later forecasts. Winds shift with the frontal passage and reach cautionary to advisory speeds but gradually subside as the high builds in then moves east.

Aviation
Some patchy fog has already developed tonight, and will
continue to cause sporadic flight category reductions
through sunrise, mainly around klal and kpgd. A band of
showers associated with a passing cold front will move
southeast through the area TAF sites during the afternoon.

Winds will increase and turn to the north-northwest behind
the front, with clearing skies through the evening.

Prev discussion issued 634 pm est Sat nov 18 2017
update (tonight)...

no weather concerns expected overnight. Skies should remain mostly
clear with light winds expected. Models are in good agreement with a
cold front moving through florida tomorrow with a chance of showers
expected along the nature coast by mid morning, tampa bay by noon
and southwest florida by mid afternoon. A 20-40 percent chance of
showers can be expected region wide. High pressure builds in behind
this front and will help filter in some cooler and drier air into
next week. No changes needed to the forecast at this time.

Marine...

main concern will be the front tracking south over the
waters during Sun with winds increasing to around 20 knots
behind it. These begin in the northern waters Sun morning
then spread south... Generally for the outer waters. Small
craft advisories most likely will be issued by sunrise sun.

High pressure builds in behind the front and tracks east
with winds diminishing and shifting through midweek. During
the last half of the week low pressure may form in the gulf
and could impact the forecasts for that period.

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.
