Area Forecast Discussion
National Weather Service Key West FL
1040 PM EST Thu Feb 23 2017

A deep cyclonic circulation persists east of Florida, supporting a
1005 mb surface low which is receding northeast into the western
North Atlantic. Deep moisture is limited along the western flank
of this system`s circulation, although periodic spokes of
stratocumulus have been successful across the Florida Peninsula
and the Keys. The KBYX radar is echo free, aside from a few
scatterers within the most robust stratocumulus cells. Northwest
winds average 12 to 15 knots at the available marine observation
stations. Temperatures are near 70 with dewpoints in the mid 60s.

Water temperatures in the mid 70s should temper overnight lows
between 65 and 70 degrees. Accumulating rain chances are nil.
Forecast sounding continue to indicate layers of stratocumulus
periodically blanketing the island chain overnight and into
tomorrow morning. The forecast is on track and needs no


Small Craft Should Exercise Caution across the southeastern Gulf
of Mexico and the Straits of Florida until swells of 6 feet
subside. Swells will likely continue for the next day or so
southeast of the Upper Keys, although height will gradual
decrease. Winds will diminish overnight through Friday night, and
Saturday`s winds will be less than 5 to 10 knots area wide.
Northeast breezes will freshen Saturday night through Sunday
night, and the strongest breezes of the next seven days will be
on Monday.


Moderate northwest breezes will persist at the EYW and MTH
terminals. Forecast soundings continue to indicate periodic MVFR
CIGS based as low as 015 at both terminals overnight. Any MVFR
CIGS will erode Friday morning as the low pressure system east of
Florida recedes east into the western North Atlantic.
