GMZ800 Synopsis For The Coastal Waters From Bonita Beach To Suwannee River- 238 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.

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.
