Discussion
Currently
Kbyx detects widely separated showers throughout the forecast
area. Skies over the island chain are partly cloudy. Winds over
land are east to southeast at 5 to 10 mph. C-man winds, on
average, are southeast near 10 knots. Temperatures are in the mid
to upper 80s.

Short term (this afternoon)
In the low to mid levels of the atmosphere, an atlantic ridge of
high pressure will extend across south central florida this
afternoon. In the upper levels of the atmosphere, an area of high
pressure will be centered over the southeastern united states
today. The 12z kkey sounding is moderately unstable and seasonably
moist, with a precipitable water value just above one and three
quarters of an inch. Atmospheric moisture will remain constant
this afternoon. Adequate atmospheric instability and moisture in
place, coupled with lack of apparent convective inhibition,
supports chance category pops today.

Marine
Gentle east to southeast breezes will prevail on all keys coastal
waters this afternoon. No advisories or cautionary headlines
expected today through Saturday. Small craft are urged to exercise
caution on the coastal waters of the florida straits Saturday
night and Sunday due to sustained east to southeast surface winds
of 15 to 20 knots. A small craft advisory may be required for the
coastal waters of the florida straits Sunday night.

Aviation
Periods of sub-vfr conditions are possible in and around any
passing showers or storms today. Otherwise,VFR conditions will
prevail at eyw and mth. A cloud line could generate afternoon
thunderstorms in the vicinity of eyw. Expect east to southeast
winds of 5 to 10 knots.

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.
