Update
Evening sea breeze and outflow mergers will focus early evening
tstorms between the i-95 corridor and highway 301 generally north
of i-10, with a drift back toward the coast under light westerly
flow generally on the northern periphery of the 1000-700 mb ridge
across the fl peninsula. Isolated shower thunderstorm activity is
possible south of i-10 over the next couple of hours where subsidence
is stronger, but expect mostly dry conditions. By midnight, dry
conditions prevail with lingering high debris clouds through the
night.

Mild and muggy conditions continue trending a bit warmer than
last night, with lows in the low mid 70s inland to mid upper 70s
coast. May have some patchy ground fog early in the morning where
recent rainfall occurred.

Aviation
Sea breeze and outflow mergers will focus best tstorm potential
early this evening near ssi and jax where tempo restrictions to
MVFR will be possible. After 02z, rainfall will fade withVFR
conditions expected to prevail through much of the night under
light SW winds calm inland to near 5 kts toward the coastal
terminals. Low potential for stratus fog near gnv and vqq and
trended toward 6sm at this time after 07z fri. Wsw winds develop
after sunrise Fri with an afternoon east coast sea breeze shifting
winds to sse at coastal terminals. Best chance of mainly
afternoon and early evening convection near the terminals
generally after 19z Friday.

Marine
Elevated sse winds this evening near 17 kts at grays reef buoy
41008 due to elevated gradient between surface ridge across the fl
peninsula and a surface trough across inland sc and ga. Winds
were near 10 kts along the local coast with the east coast sea
breeze. Tonight, winds will back more ssw and range near 10-15 kts
as synoptic scale flow prevails with microscale land breeze
development. Combined seas 3 ft or less offshore, 2 ft or less
nearshore.

Rip currents: moderate risk NE fl beaches, low risk SE ga through Friday.

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.
