Update Cold front stretching from NW ga to SE al will
weaken tonight as an upper ridge begins to build in from the south.

A cluster of showers and storms out just ahead of it will not make
any further progress to the southeast as a result. A few isolated
showers are still possible across the far NW zones generally north
and west of line from douglas to alma.

The smoke plume from the west mims wildfire will move north tonight
affecting areas around racepond... Folkston... St george... And
possibly as far north as waycross. Visibilites across these areas
will be reduced to 1 to 3 miles but may be locally less then 1 mile
near and just north of the wildfire.

00z jax sounding indicated the pw increased to 1.55. This increase
in moisture may lead to patchy low clouds and fog especially towards
the gulf coast and possibly the atlantic waters. The SREF continues
to show high probabilites of dense fog towards the gulf and have put
in areas of late night fog for the western areas of the suwannee
valley.

Aviation Patchy low clouds and fog possible later tonight
with best chances at gnv between 09z-13z. Confidence is low on
extent of it although have carried previous fcst of MVFR cigs.

PrevailingVFR CIGS expected most everywhere else although
monitoring ifr CIGS currently at ssi which may require an upcoming
amending.

Marine Data buoy obs indicate winds are sse 15 to 20 knots
across much of the waters so have expanded the exercise caution for
all of the waters. The trend will be for winds to veer and gradually
decrease later tonight.

Rip currents: low risk expected through Friday.

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.
