Area Forecast Discussion
National Weather Service Key West FL
Issued by National Weather Service AUSTIN/SAN ANTONIO TX
210 AM EDT Mon Sep 11 2017

.UPDATE...
Updated for 06Z aviation update below.

&&

.Prev Discussion... /issued 1148 PM EDT Sun sep 10 2017/
An upper level trough is evident on water vapor satellite imagery
to the northwest of Hurricane Irma. This feature will keep Irma
on a north to north- northwest track tonight.

.CURRENTLY...
At 11 PM the center of Irma was located about 40 miles ENE of
Sarasota moving northward at 14 mph. Irma is expected to remain
over the western Florida peninsula tonight and Monday.

.SHORT TERM...
As Irma continues to move away to the north, conditions are slowly
improving across the Keys. The Hurricane Warning has been
downgraded and the Florida Keys and all of the surrounding near
and offshore waters are now under a Tropical Storm Warning. With
these strong west to southwest winds continuing tonight the Storm
Surge Warning remains in effect for the Florida Keys. However,
with the decrease in the wind speeds the storm surge inundation
will be 3-5 feet. This will still be a life threatening amount of
water.

&&

.MARINE...
Tropical storm conditions will persist overnight making marine
conditions dangerous. Winds and seas will gradually subside on
Monday.

&&

.AVIATION...
Both Key West and Marathon airports are still closed. Weather
conditions are slowly improving. Winds are transitioning from
Southwest to West-southwest at 16 with gusts to 26 kts with gusts
decreasing around daybreak. A few gusts to 25 kts could return by
15z as winds remain West-southwest. There will be occasional rain
showers overnight. Skies should also improve to VFR toward
daybreak.

&&

.KEY WATCHES/WARNINGS/ADVISORIES...
FL...Tropical Storm Warning for FLZ076>078.
FL...Storm Surge Warning for FLZ076>078
GM...Tropical Storm Warning for GMZ031>035-042>044-052>055-072>075.
