Discussion
Currently - a surface ridge extending across central florida is
producing light to gentle east breezes across the area. Near
normal instability and moisture, along with a number of cloud
lines, has generated isolated to widely scattered showers, and a
few thunderstorms across the forecast area.

Short term update - ridging to our north will maintain generally
light east breezes. Some localized perturbations are expected due
to day time heating over south florida. Guidance suggests that
lower level flow will become a more uniform east northeast, which
will be supportive for island cloud line development. This along
with the already existing active boundaries, justifies maintains
the somewhat above normal rain chances for this afternoon. Expect
typically hot and humid conditions.

Marine
Winds will be light to gentle and mainly out of the east. Some
additional backing will likely occur on our gulf side waters, an
expression of day time heating over south florida. Essentially
zero changes made in the morning marine update.

Aviation
The chance of shower impact is higher than climatology today, so
expect vcsh to remain until a slight lull in coverage after 18 00z.

Sub-vfr conditions will be possible with any passing shower or
thunderstorm, and amendments to the terminal forecast will be issued
as necessary. Outside of shower activity, expect winds out of the
east to east-southeast near 7 knots.

Climate
On this date in keys weather history, in 1886, an unnamed tropical
storm intensified into a hurricane as it moved west northwest
through the straits, about 50 miles south of key west. A minimum
pressure of 29.66 inches of mercury was recorded. A man was killed
when a building collapsed on duval street in key west.

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.
