Discussion
Currently
A few to scattered cumulus have been streaming overhead, with
fairly extensive cirrus coverage above it courtesy of tropical
storm nestor in the gulf. As mentioned in the morning discussion,
only a couple of small showers have appeared on key west radar,
mainly in the gulf waters. Winds across the islands have remained
below 10 knots, with a distinct increase of a few knots from east
to west. The same can be found in the cman platforms along the
reef, with alligator reef from 5 to 10 knots increasing westward
to near 15 knots at pulaski shoal light.

Short term
All indications from observations and guidance point towards a
slow increase in winds this evening and overnight along the
western portions of our area of responsibility. As nestor pushes
ashore in the florida panhandle tomorrow morning and continues
moving northward, winds will slowly begin to taper off over the
keys and coastal waters by tomorrow late afternoon and begin to
veer to southwesterly. Overnight, shower coverage will likely
increase slightly as the wind increases, aided by nocturnal
marine boundary layer instability over the toasty warm waters, as
well as directional and speed convergence with the building
winds. All in all, it should remain a good night for festival
activities in downtown key west this evening and tomorrow, with
just the possibility of a shower moving quickly through.

Long term
Winds over the area should continue to decrease through the
weekend into early next week with nestor moving through the
southeastern states and then off the eastern seaboard. This will
disrupt the western atlantic ridge, leaving a weak ridge axis over
the keys area. The ridge will begin to build back into place over
south florida in the wake of nestor, with east to southeast flow
returning in earnest. Of course, the big excitement this time of
year is the approach of the first cold front, which unfortunately
looks at this time to push into the florida peninsula by Wednesday
morning and then halt progress southward. There is hope though,
as the GFS is showing a front pushing through around the 26th or
27th. Stay tuned.

Marine
As tropical storm nestor treks towards the florida panhandle,
winds in our westernmost straits and gulf waters will slowly
increase and seas begin to build. A small craft advisory will be
issued this evening for the gulf waters and florida straits
waters south and west of the dry tortugas as winds will approach
20 knots and seas will build to 7 feet and possibly higher
overnight, before conditions begin to improve late tomorrow. By
tomorrow night winds will decrease, and seas will begin to relax,
so at this time it does not appear that advisory conditions will
persist past tomorrow afternoon.

Aviation
Vfr conditions will prevail this evening and overnight at both the
key west and marathon terminals. The current south southeast winds
of 5 to 10 knots will slowly begin to increase this evening to 10
to 15 knots and become more southerly. Shower and thunderstorm
chances will also increase overnight, but should remain isolated
in nature. Therefore, any reductions in ceiling and visibility
will not be included in the terminal forecast at this time since
any shower or storm will pass quickly and confidence in shower
development and location is not high.

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.
