Update
Forecast remains in good shape. Lingering diurnal thunderstorm
activity near the i-75 corridor along a weak surface trough
oriented southwest to northeast. This activity should wind down in
the next hour but we cannot rule out a few additional isolated
showers storms over the next few hours into the early morning
hours. Most areas though will remain dry overnight. Muggy
conditions however will prevail.

Aviation
Vfr will prevail through Thursday morning. There will be some more
afternoon thunderstorms on Thursday but not enough coverage to
warrant any inclusion in the taf's this far out.

Marine
Southerly winds 10 to 15 knots will slowly veer to the southwest
overnight. Seas will average 2 to 4 feet. No changes needed.

Rip currents: a persistent and long period east southeasterly ocean
swell will keep a moderate risk of rip currents in place at this
time.

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.
