Warmer tonight under high clouds...

Widespread rainfall Friday will prolong and or worsen river
flooding across parts of the suwannee river valley and potentially
inland southeast georgia...

Update
Warmer with mostly dry conditions tonight as surface high pressure
ridge center builds offshore of the SE atlantic coast. Abundant
high clouds will limit fog formation and keep temperatures more
mild generally in upper 30s to low 40s inland, to mid upper 40s
toward the st. Johns river basin and atlantic coast. Removed frost
from forecast given high clouds, but did include some patchy sea
fog drifting inland from the atlantic along the SE ga coast where
temps and water temps were in the mid upper 50s and bqk reported
recent restriction. Hrrr advertised reduced visibility lingering
under the low level ridge axis across coastal SE ga through the
night. A low chance of coastal showers will lift up the NE fl
coast early Thu morning with increasing low level clouds as a
coastal trough morphs into a lifting warm front.

Aviation
Vfr conditions tonight, with a very low chance of sea fog
impacting ssi based on observations at bqk, water temps surface
temps in the mid upper 50s and latest hrrr model run. Elsewhere
abundant high clouds will limit fog potential. Winds transition to
ese through Thursday with restrictions to MVFR most probable at
sgj in the afternoon, shifting northward up the coast through the
evening with a low chance of showers as warm front lifts northward
over the area. Further restrictions expected into Thu night.

Marine
Surface high pressure will build offshore of the southeast atlantic
coast through Thursday. Light ese winds 10 kts or less tonight
with combined seas 3 ft or less. Some sea fog potential near the
se ga coast tonight. South winds will increase over the waters
ahead of an approaching front Thursday night with advisory
conditions expected for at least the outer waters.

Rip currents: moderate risk Thursday.

Hydrology
Moderate flooding continued this evening along the alabaha basin,
with minor flooding along the satilla and altamaha.

Significant river rises expected this weekend due to widespread
heavy rainfall Friday, which will prolong current flooding issues
and even worsen flooding in some areas across inland SE ga and
the suwannee river basin.

Latest forecast guidance advertised white springs and suwannee
springs along the suwannee river rising into moderate flood stage
this weekend with 3-4 inches of rainfall. Ongoing flood issues
near suwannee springs camp and fox hollow will continue (potentially
worsen) into the weekend.

Interests near flooded rivers tributaries across SE ga and the
suwannee river valley, please closely monitor the latest river
forecasts and heed advice of local emergency management.

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.
