Area Forecast Discussion
National Weather Service Key West FL
216 PM EDT WED SEP 28 2016

.DISCUSSION...
.CURRENTLY...
KBYX detects no precipitation echoes in the forecast area. Skies over
the island are mostly sunny. Winds over land are south to southwest
at 5 to 10 mph. C-MAN winds, on average, are south to southwest at 5
to 10 knots. Temperatures are in the mid to upper 80s.

.SHORT TERM (Tonight through Friday night)...
An Atlantic ridge of high pressure will extend across the Florida
Straits tonight. This ridge of high pressure will retreat eastward
Thursday. A trough of low pressure will slowly progress southward
through north Florida Thursday night through Friday night. Meanwhile,
Tropical Storm Matthew is located near the Lesser Antilles. This
tropical storm could intensify into a hurricane by Friday as it
progresses in a general westward direction through the eastern
Caribbean Sea and into the central Caribbean Sea. Only minor
changes are planned to the short term portion of the forecast.

&&

.LONG TERM (Saturday through Wednesday)...
The long term portion of the forecast is littered with uncertainty
due to significant differences among track forecast computer models
regarding Tropical Storm Matthew. No changes to the long term portion
of the forecast until these computer models come into better
agreement. It is too early to determine, what, if any, impact this
tropical cyclone will have on the Florida Keys.

&&

.MARINE...
Light south to southwest breezes expected on all Keys coastal waters
tonight. No advisories or cautionary headlines expected tonight
through at least Sunday night.

International Terminals through at least 29/18z.

hurricane made landfall near Tavernier, with maximum sustained winds
of around 115 mph. Railroad service to the Florida Keys was out for

south as Big Pine Key. The Coast Guard had to provide mail service to
