1105 am edt Tue aug 20 2019

Short term
The 12z key sounding showed substantial moistening since yesterday
morning, with the pw value back up to well above normal value of
2.17". Meanwhile, an upper level trough axis trails back across
the straits from a tutt low over the northern bahamas.

For this afternoon, visible satellite imagery shows an outflow
boundary spreading westward out of the convective activity east of
andros island. As of this writing, it is within an hour of
reaching the far eastern tip of the forecast area northeast of the
cay sal bank. Mesoscale models show the boundary continuing to
spread west this afternoon through the eastern straits and into
the upper middle keys, with additional shower and thunderstorm
development this afternoon focused primarily along the boundary.

Marine
Added an exercise-caution headline to the eastern straits for this
afternoon. Satellite imagery shows a surge of wind spreading out
from a convective cluster east of andros island, and mesoscale
models bring that across the eastern straits early this afternoon
with a period of gusty winds. Of course, all the waters will be
subject to gusty convective outflows, but it looks most widespread
and prolonged over the eastern straits this afternoon.

Past this afternoon, gentle to moderate east breezes will prevail
in response to a subtropical atlantic ridge axis over far north
florida. The next tropical wave should cross the waters around
Friday. On Saturday, the subtropical ridge axis will weaken and
settle south toward central florida.

Aviation
Through 21 12z, prevailingVFR conditions are expected at both eyw
and mth. The atmosphere has turned markedly more moist and unstable
during the last few days, and this trend will persist, with above-
average rain thunder chances expected. However, timing of any sub-
vfr impacts at either eyw or mth will remain thorny due to the
unorganized nature of shower and thunderstorm development. Cell
movements will average from 115 12 knots.

Climate
In 1963, the daily record low temperature of 69 degrees was
recorded in key west. Temperature records date back to 1872.

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.
