Update
Strong pressure gradient remains due to 1030 mb high over the mid
atlantic area and lower pressure across the fl straits to the
bahamas. Northeast flow continues strong but now confined to the
beach areas with sustained winds 15-25 mph and a few gusts around
35 mph. Strongest winds are along the northeast fl coast with
speeds several mph lower along the ga coast. Will allow wind advy
to expire. Coastal convergence and weak upper support continues
to support chance showers for areas southeast of a line from
mayport to palatka and over the northeast fl coastal waters. Over
the next 12 hours, showers will begin to shift further south and
east as drier advects in from the north as mean low level flow
begins to become more northerly Wednesday morning, helping to
weaken the convergence. Other than tweaks to the lows tonight that
will be in the 40s over inland southeast ga and the suwannee
valley and 50s elsewhere, little change to the current public
forecast.

Aviation
Vfr expected to prevail though CIGS at terminals near or above
4000 ft into Wed morning. Improved skies expected Wed aftn as
drier air filters into the region. Winds will continue to diminish
overnight, except at ksgj where north-northeast winds near 15-20
kt with gusts to near 25-30 kt are possible. Much lower wind
speeds on wed. A few showers will be near ksgj over the next few
hours.

Marine
Strong SCA conditions for area waters expected rest of tonight.

Little change to the forecast except some tweaks to up the winds
and seas for tonight-wed based on obs. High surf advy and high
risk of rip currents will continue with the strong north-northeast
flow.

For coastal flood conditions, all the coastal observing tide
stations have reached between the action to just below minor
flood categories with the evening high tide. The higher
astronomical tide is Wed morning and extra-tropical surge guidance
(anomaly) will be near 1 to 1.5 feet so the coastal advy looks
good at this time.

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.
