Update East coast seabreeze pushed well inland to the
suwannee valley this eve and produced no convection due to
strong subsidence. The southeast flow behind it will gradually
weaken tonight but will push the smoke plume from the west mims
wildfire to the northwest. Visibilities will be reduced to less
than 1 mile at times near and just northwest of the wildfire.

Moist sse flow may bring in patchy low clouds overnite but
high-res models not very robust on fog probably due to elevated
boundary layer winds.

Aviation Patchy low clouds and fog possible later tonight
with best chances at gnv and vqq between 08z-13z. Confidence is
low on extent of it although have carried previous fcst of MVFR
vsby with scattered low decks at 500 ft. There may also be
patches of low clouds near the coast and went with scattered
low decks around 800 to 1000 ft at ssi and sgj.

Marine Current data buoy obs indicate winds are sse near
15 knots. These winds will continue overnite with a slight
reduction towards dawn and into early Saturday morning
before an early afternoon surge with the seabreeze.

Rip currents: moderate risk through Saturday due to an
onshore flow and a long period swell.

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.
