Update
A clear and mild day today with temperatures in the lower to mid
70s over georgia and the mid to upper 70s over florida. Will be a
bit gusty at times with wind gusts of 20 to 25 mph, especially
over the florida east coast.

Aviation
Vfr conditions today with wind gusts near 20 knots being the main
problem.

Marine
Sea will be a bit slower to decease this afternoon and will hold
the offshore small craft advisory through 3 p.M. And likely drop
it down to a small craft exercise caution with the afternoon
update. Otherwise, gusty winds offshore will make even the near
shore waters uncomfortable with wind gusts of 20 to 25 knots. Will
maintain the small craft exercise caution between the beaches and
20 miles offshore.

Rip currents: two foot easterly swells will support a moderate
risk of rip currents today, and that is expected to drop to a
low risk on Saturday.

Fire weather
Critically low rh again today but average wind speeds will likely
stay below 15 mph area-wide so no red flag warnings. That said,
wind gusts in the 20 to 25 mph can be expected. Dispersion values
will be a bit elevated in a few areas. Saturday, critically low
rh values again mainly inland areas and winds will likely again be
less than 15 mph. Sunday, min rh values not as low due to gradual
increase in low level moisture.

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.
