Area Forecast Discussion
National Weather Service Key West FL
1041 PM EST Tue Jan 17 2017

Deep ridging is in control this evening, with local Doppler radars
void of precipitation echoes.  A surface high pressure ridge is
moving slowly southward, with a resulting decrease in gradient flow.
However, winds have been slow to come down across the lower Straits
of Florida.  Currently, air temperatures in most Keys island
communities are in the mid 70s, with dewpoint temperatures mostly
in the mid 60s.  Only a few to scattered cumulus are populating
the evening skies across the service area, moving toward the
west-northwest.  The local digital forecast database has been
adjusted slightly.

The Small Craft Advisory was discontinued for the Straits of Florida
zones from Ocean Reef to the west end of the Seven Mile Bridge.
A Small Craft Advisory remains in effect for the lower Straits of
Florida.  A "Small Craft Should Exercise Caution" headline applies
to Hawk Channel and portions of the extreme southeastern Gulf of
Mexico.  An Atlantic ridge of high pressure will extend across
northern Florida overnight and Wednesday.  The high pressure area
will shift eastward Wednesday night and Thursday.  The next cold
front may arrive Sunday night.

Through 18/24Z, prevailing VFR conditions are expected at both EYW
and MTH.

On this date in Florida Keys weather history, in 2011, 1.91 inches
of rain fell at Key West International Airport. This set the daily
record for maximum rainfall measured in Key West on January 17th.
Rainfall records at Key West date back to 1871.

GM...Small Craft Advisory in effect for GMZ054-GMZ055-GMZ074-GMZ075.
