Becoming windy along the coast on Tuesday with rough surf, high
risk of rip currents and possible minor coastal flooding...

Update
Much drier airmass over the region as lower humidities advect in
on deep layer northwesterly flow. Skies generally partly cloudy
with mid and high clouds at times as an upper level trough over
nrn mexico and tx heads eastward toward our area. In fact, upper
level clouds will likely increase thicken as we approach this
evening. Temps are currently in the 40s over ga suwannee valley
and 50s to near 60 over rest of northeast fl. Enough breaks in
clouds for highs to reach the 60s to around 70, with northeast
winds, gusty near the coast. Another wave of low pressure will
form along the front located over the fl straits tonight bringing
a northward surge in moisture and a chance of rain to our SE zones
late tonight. Low temperatures tonight will be in the 40s inland... To
the lower 50s coast.

Aviation
Vfr conditions today with mid and high level clouds at times.

Winds will be from the nne today at 10 to 15 knots with gusts to
around 20 knots at sgj and crg. Increased clouds tonight and any
possible CIGS getting close to MVFR would be Tuesday morning for
sgj and crg.

Marine
Scec conditions expected today due to tighter pressure gradient
with lower pressure to our south and sprawling high pressure over
the central and ERN u.S. The main cwf updates were to raise sca
beginning tonight and continue through mid week and also to adjust
forecast wave heights today based on current buoy obs. What is
also concerning is a possible need for a gale watch-warning, if
indeed we see more frequent gusts to gale force in the tue-wed
time frame.

Seeing coastal water levels moving toward action stage, within a
few tenths, but not expected to have any issues through tonight.

As we continue to have increased winds and onshore flow and
approach full moon tue-thu, minor coastal flooding is possible at
high tides, with water levels near the 1 to 1.5 feet range above
the astronomical high tide.

Rip currents: moderate rip current risk today and surf will be
rough choppy. High risk on Tuesday and Wednesday as winds increase
and become more onshore producing rough surf with breakers
increasing to near 7 feet.

Fire weather
Low humidities are expected this afternoon in the 20-30% range over
inland areas but winds are expected to be less than 15 mph in the
those inland areas. Elevated dispersion values possible due to
higher mixing heights today.

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.
