Marine Weather and Tides
Key West, FL

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Discussion
Isolated showers are occurring along an old outflow boundary
drifting southwest offshore the everglades, and upon intersection
over island convergence over the middle and upper keys. The
evening sounding contained about two tenths of an inch
precipitable water, with pronounced dryness above 3000 ft. The
sounding was unstable, but much of that due to the plentiful sun
earlier today and temperatures in the mid 80s. With light winds
some actual slight cooling into the lower 80s has already taken
place back from the shores.

Other than the furthest south extent of the east coast seabreeze
bringing a 9-knot east breeze to carysfort reef, winds were light
and variable as the weak western extension of the western
atlantic surface ridge remains bifurcated from early heating of
the florida peninsula. Light and variable winds will continue,
with the slow drift of small showers and possibly a thunderstorm
along old mesoscale boundary interactions can be expected
overnight.

Marine
Light and variable winds can be expected near the islands,
gulfside and bayside overnight through at least Thursday,

Aviation
Expect prevailingVFR conditions at eyw & mth through at least
21 00z. Variable, nearly calm winds will become predominantly out of
the south-southwest near 5 knots by afternoon. Shower impact via
cloud-line or land breeze from S florida will remain a distant
possibility through the terminal forecast period, with chances
highest in the afternoon.

Climate
On this date in keys weather history, in 2012, 3.23 inches of rain
was recorded in key west. This set the daily record for rainfall in
the city. Precipitation records for key west date back to 1871.

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.
