Area Forecast Discussion
National Weather Service Key West FL
358 AM EDT Sun Sep 24 2017

Hurricane Maria is moving north near 10 mph and located about 600
miles south-southeast of Cape Hatteras, meanwhile recently
upgraded hurricane Lee is churning over the central Atlantic about
860 miles east of Bermuda. Closer to home, winds are out of the
northeast to east at 5 to 10 knots from the island terminals, and
near 10 knots at the marine reporting stations.

Only change to the current forecast is to lower rain chances today
due to the dry air surrounding hurricane Maria, and deep layer
high pressure. Winds will remain weak while the Keys area is stuck
in the COL region between the storm and the high pressure to our
north and south. Will keep the chance of showers and slight chance
of thunderstorms overnight due to lingering boundaries moving off
the Peninsula or Cuba. Moisture will gradually return and even
with gentle to light winds at the surface, the vertical wind
profile should become more viable for precipitating cloud lines
through the end of the week.


No advisory or cautionary statements are expected through the end
of the week. A weak pressure gradient is responsible for the
gentle to light winds across the area.


Today, VFR conditions will prevail at both KEYW & KMTH island
terminals. a few showers may impact the terminals around KMTH,
resulting in brief MVFR/IFR ceilings and/or visbilities until
about 10Z. Variable surface winds AOA 5 knots or less, will
become north to northeast. Expect few-sct cumulus clouds with
bases AOA FL020-025, except broken in and near any showers.


In Keys Weather History, on September 24th 1963, the low
temperature at the Key West International Airport dropped to 72
degrees. This set the daily record for minimum temperature for Key
West on this date. Temperature records for Key West date back to
