Much needed rainfall continues...

Record precipitable water value for the date of 2.06" measured
at jax this evening...

Update Prevailing SW steering flow focused the heaviest and
most widespread rainfall this afternoon and evening generally
along and east of a jesup ga to gainesville fl line as the
stronger west coast sea breeze interacted with lingering old
outflow boundaries and river/lake/sea breezes across the eastern
half of the forecast area. Locally heavy rainfall with 2-3 inches
of measured rainfall in 2 hours was realized in some locations,
with wet downburst winds due to heavy precip loading causing some
tree and structure damage.

For the remainder of the night the best chances of passing showers
and isolated tstorm activity will be across SE ga... And especially
along and near the altamaha river basin where a quasi-stationary
frontal zone meandered and was being over-ridden by passing mid
level short wave trough vorticity from the wsw. This forcing
combined with an unseasonably moist airmass will continue to bring
waves of locally heavy rainfall across portions of SE ga through
the night... With amounts potentially up to 2-3 inches in places.

Most locations welcome this needed rainfall but given the
relatively short duration of heavy rainfall flooding potential
will exist especially in areas that have training convection, or
waves of showers and storms following the same path near the altamaha
river tonight.

Rain chances will increase early Tue morning form the gulf coast
region where radar and satellite trends indicated an MCS forming
south of la. Recent short range forecast models started to
indicate outflow from this system sparking some early morning
convection moving inland across our suwannee river valley zones
Tuesday morning.

Muggy and warm temperatures will continue overnight under partly
to mostly cloudy skies. Some low stratus and ground fog will be
possible Tue morning especially where locally heavy rainfall feel
this afternoon/evening.

Aviation Showers and potentially an isolated tstorm will be
most probable at ssi over the next several hours. Elsewhere
prevailingVFR expected until after midnight with the potential
for low stratus and patchy ground fog due to high ground moisture
at all NE florida terminals due to rainfall today. Based early
morning restrictions to MVFR at gnv on persistence and ifr at
vqq. Another wave of showers and tstorms expected Tuesday with
activity first likely impacting gnv and ssi.

Marine Small craft exercise caution winds sse 15-20 kts this
evening with fading convection will veer more ssw after midnight.

Combined seas of 2-4 ft will continue due to prevailing offshore
flow.

Rip currents: low risk of rip currents Tuesday.

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.
