Discussion
Currently
Kbyx detects widely separated showers and isolated thunderstorms
over the coastal waters of the florida straits. Elsewhere, kbyx
detects no precipitation echoes in the remainder of the forecast
area. Skies over the island chain are partly cloudy. Winds over
land are northeast to east at 10 to 15 mph. C-man winds, on
average, are east at 10 to 15 knots. Temperatures are in the lower
to mid 80s.

Short term (today through Monday)
An upper level area of low pressure will move westward through the
southeastern gulf of mexico today. A tropical wave, currently
over the bahamas, will approach the florida keys tonight. This
tropical wave will pass through the service area Sunday, before
entering the southeastern gulf of mexico Sunday night and Monday.

Rain chances in the short term portion of the forecast will be
highest Sunday due to the aforementioned tropical wave passing
through the florida keys.

Long term (Monday night through Friday)
An upper level area of low pressure will move over the florida
keys Monday night, before weakening Tuesday. A trough of low
pressure should approach the florida keys Tuesday night. This
trough of low pressure should pass through the service area
Wednesday into Wednesday night. An atlantic ridge of high pressure
will slowly build across south florida Thursday through Friday. No
changes to the current long term portion of the forecast.

Gentle northeast to east breezes will prevail on all keys coastal
waters today. No advisories expected today through at least
Sunday. A small craft advisory may be required for the coastal
waters of the florida straits Sunday night. A small craft advisory
may be required for all keys coastal waters Monday and Monday
night. No advisories expected Tuesday through at least Wednesday
night.

Aviation
Expecting mostlyVFR conditions through at least 19 23z at both the
key west and marathon international terminals. With that being said,
light northeast to east winds will promote cloud line development,
and offer potential for MVFR to very brief ifr episodes at either
of the terminals after 19 12z. Outflow boundaries from
thunderstorms over south florida and cuba, combined with deep
tropical moisture, will offer a round or two of showers and
thunderstorms after 20 00z. Vicinity showers are in the terminal
forecasts at this time, but will update when evidence and timing
is revealed.

On this date in florida keys weather history, in 1924, 1.40 inches

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.
