Marathon, 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.

area forecast discussion
national weather service key west fl
1123 pm edt Fri may 25 2018

Discussion
The cloudy, rainy, and squally pattern persists. Heavier rains and
storms earlier this evening have moved over the northern marine
zones, with mainly patchy light to moderate rain across keys
island communities, with the heaviest rain currently from grassy
key to tavernier. Current air temperatures are rain-cooled, in the
mid 70s, with dewpoint temperatures in the lower to mid 70s.

Moderate to fresh southeast breezes prevail.

Highly asymmetric subtropical storm alberto is drifting
erratically around the northwestern caribbean. A mesoscale
convective system is evident in satellite animations over the
waters just south of central cuba, with scattered sporadic deep
convection elsewhere.

No significant changes to forecast reasoning overnight. Rain,
showers, and some storms will re-develop and likely overspread the
service area again before daybreak, with a stormy, and
increasingly windy day on Saturday.

Marine
At 11:00 p.M. Edt, subtropical storm alberto was centered over
the northwestern caribbean sea about 400 nautical miles southwest
of the port of key west, moving east at 5 mph. A slow erratic
motion toward the north is expected overnight. From Saturday
afternoon into Sunday, a general northward motion at a faster
forward speed is expected. Gradual intensification is expected
overnight through Sunday night. Tropical storm conditions are
possible in portions of the lower straits of florida and extreme
southeastern gulf of mexico Saturday night.

Aviation
Through 26 24z, prevailingVFR conditions are expected at both eyw
and mth. However, several sub-vfr episodes and some sub-ifr
periods are likely at both terminals. Multi-layered, mostlyVFR,
ceilings will prevail, with occasional (transient) MVFR ceilings.

Thunderstorm impacts are possible as well, at just about any time.

Climate
13.08 inches of rain have fallen at key west so far during may
2018 (as of about 9:00 p.M. Edt), already surpassing the monthly
record of 13.01 inches, set in may 1904. Therefore, may 2018 now
is the wettest may on record at key west, with six days left in
the month.

In addition, a new daily rainfall record for may 25 has been
established at key west, with 3.40 inches falling as of 9:00 p.M.

Edt. The previous daily rainfall record for may 25 was 3.34
inches, observed in 1985.

Rainfall records for key west date back to 1871.

Key watches warnings advisories
Fl... None.

Gm... Small craft advisory until 5 pm edt Saturday for gmz032>035-

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
