Discussion
Currently
Early visible satellite photographs show skies are mostly sunny
with southeast to south winds of around 10 mph. Temperatures are
already in the mid 80s along the florida keys. Meanwhile, local
radars are void of any precipitation echoes in our entire area. On
our marine district, winds are southeast to south ranging from 9
knots at pulaski shoal light to 13 knots at carysfort reef light.

Otherwise, our morning sounding reveals scant moisture below a
stable layer near 950 mb, with gentle to moderate, veering
southeast to southwest winds reaching well into the troposphere.

Furthermore, the 850 mb relative humidity is only 39 percent.

Short term (rest of today)
a western atlantic, east-west oriented, deep tropospheric,
(594 dm height) ridge axis will hold firm across the bahamian
chain and cross our entire area. This will result in significant
large scale descent (arm and hammer) which will limit moisture
to below a subtle inversion based near 2000 feet. Given a lack of
both moisture and confluence, zero pops will be kept in the grids.

Resplendent sunshine along with light to gentle southeast to south
winds will allow high temperatures to climb to around 90 degrees
along most island communities. Since the current forecast has
these weather elements covered well, no adjustment is planned.

Marine
With the western atlantic ridge axis meandering from the straits
of florida to south florida, light to gentle southeast to south
winds will become mainly light by late this morning. However, a
subtle wind increase is expected this evening and especially
tonight.

Aviation
Vfr conditions will prevail at both the key west and marathon
terminals through this afternoon and evening. Cloud coverage will be
limited to a few cumulus around fl020. Near surface winds will be
from the south southeast to southeast near 10 knots.

Climate
In 1933, the daily record cold high temperature of 81 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.
