THIS HAZARDOUS WEATHER OUTLOOK IS FOR THE FLORIDA KEYS AND
ADJACENT COASTAL WATERS.

.DAY ONE...TODAY AND TONIGHT

Isolated thunderstorms are possible along the Florida Keys and the
surrounding coastal waters today. For tonight, a Small Craft
Advisory may be required for at least a portion of our marine
district along with the possibility of scattered thunderstorms
for our entire county warning area.

Furthermore, locally heavy rainfall is likely tonight.

The primary thunderstorm hazards will be cloud to surface lighting
strikes and strong gusty winds, especially tonight when Special
Marine Warnings may be necessary for wind gusts of 40 mph or
higher.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY

For Saturday and Saturday night, low pressure north of the
Yucantan Channel is expected to intensify as it tracks north
northwestward, resulting in strengthening southerly winds and
increasing thunderstorm coverage. Because of this, a Small Craft
Advisory, Gale Warning or perhaps a Tropical Storm Warning may
be required for portions of our coastal waters. In addition,
a few stronger thunderstorms may generate wind gusts in excess of
45 mph, waterspouts and perhaps a few tornadoes.

Please stay tuned to NOAA weather radio, our web site,
weather.gov/key for the latest statements and or warnings issued
by your National Weather Service right here in Key West.

For Sunday and Sunday night, a Small Craft Advisory may be
required for portions of Keys coastal waters. In addition,
isolated thunderstorms are possible along the Florida Keys and the
surrounding waters.

For Monday through Thursday, A Small Craft Advisory may be
necessary for at least a portion of our coastal waters on Monday,
otherwise, isolated thunderstorms are possible through this period.
