Update
The remaining convection over land is over the suwannee valley and
should diminish by midnight. Showers and isolated thunderstorms
should increase in convergent bands over the coastal waters and
encroach on the land areas after midnight.

Aviation
A few remaining showers over the suwannee valley should dissipate
by midnight and remain west of the main fields. With a persistent
low level easterly flow should see ocean low cloudiness between 2
and 4 kft and a few showers roll off the atlantic through 14 utc
tomorrow and then with diurnal heating a better chance of
convection after that across the region.

Marine
A surface trough lingering across the local waters will lift
north Monday. Grays reef buoy is coming in solidly between 15 to
20 knots this evening and will continue the scec headline for
the waters through tonight. A front will settle across south
georgia Tuesday and linger through Wednesday with a broad low
expected to form along this boundary late in the week. That low
then then gradually shifts westward this weekend as high pressure
builds north of the local area.

Rip currents: moderate risk.

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.
