GMZ800 Synopsis For The Coastal Waters From Bonita Beach To Suwannee River- 331 Am Est Mon Nov 20 2017
Synopsis..A cold front across the southern florida peninsula early this morning will move into and stall out across the florida straits later this afternoon and tonight as surface high pressure over the southeastern states slides east northeast toward the mid atlantic coast. Strong and gusty north winds over the gulf waters early this morning will diminish some by later this morning and into the afternoon as the flow veers into the northeast and east. Tonight into Tuesday the high will shift east into the atlantic as an area of low pressure develops over the gulf. As this low develops the stalled frontal boundary across the florida straits will lift back to the north as a warm front on Tuesday. Increasing moisture combined with the warm front and developing low pressure over the gulf will bring increasing rain chances and isolated Thunderstorms to the gulf waters on Tuesday and continuing through the end of the week as this storm system continues to affect the region.

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.
