Update
Lead energy shortwave over the SE gomex and is poised to track ne
across the fl peninsula this afternoon and still on track for
scattered to numerous areas of light to moderate rainfall for ne
fl and coastal SE ga with lesser coverage for inland SE ga. Milder
se flow should still be enough along with possibly a few sunny
breaks to push temps into the lower to middle 70s and allow for
enough instability for some embedded isolated storms. Rainfall
amounts this afternoon and evening still appear to be in the
0.25-0.50" range across NE fl south of i-10, and less than 0.25"
elsewhere across the area. Tonight... Rainfall still possible
during the evening hours until the shortwave energy pushes NE and
offshore into the WRN atlc and this will set the stage for
widespread low clouds and fog developing after midnight with
fairly high chances of dense fog late tonight early Wed morning
and a dense fog advisory could be required for most of NE fl se
ga. Mild conditions will continue with lows in the 50s.

Aviation
Vfr with mid high clouds this morning, then chances of MVFR
cigs vsbys increase with rain chances this afternoon evening. Tstm
chances still too low to include in forecast. Following the end of
rainfall this evening, models are coming into better agreement for
low clouds and fog with ifr lifr conds possible by 06-12z tonight.

Marine
Forecast on track with east to southeast winds 10-15 knots and
seas 3 to 5 feet, just below scec levels today. Winds shift back
to the northeast later tonight after first weak wave of low
pressure passes off the coast.

Rip currents: moderate risk in the onshore flow this week.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
