This Hazardous Weather Outlook is for the Florida Keys and
adjacent coastal waters.

.DAY ONE...Tonight.

Minor coastal flooding associated with seasonal king tides will
continue tonight.

Isolated thunderstorms will be possible tonight. The primary
hazards will be heavy downpours, locally gusty winds, and
lightning strikes.

A Tropical Storm Watch is in effect for the Lower Keys and the
coastal waters west of the Seven Mile Bridge. Tropical Storm
Conditions are possible within the next 48 hours.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday.

Potential Tropical Cyclone Nine located in the western Caribbean
will move northwestward on Tuesday and Tuesday night, followed by
a faster northward to north- northeastward motion on Wednesday
and Thursday. On the forecast track, the center of the system is
forecast to move across the northwestern Caribbean Sea through
Tuesday night, and then over the eastern Gulf of Mexico on
Wednesday and Thursday. Strengthening is expected during the next
few days, and the system is forecast to become a hurricane on
Wednesday and continue strengthening on Thursday as it moves
across the eastern Gulf of Mexico.

Strong southeast winds could also aggravate existing higher than
normal tides, leading to minor saltwater flooding across the
Florida Keys. Water levels are expected to peak at 3 feet above
ground, or mean higher high water. A Coastal Flood Watch may be
required.

At this time, we expect strong winds and building seas across the
Florida Keys coastal waters beginning Tuesday night, and Small
Craft Advisories will likely be required for mainly waters east of
the Seven Mile Bridge from Tuesday night through Friday.

3 to 6 inches of rainfall will be possible during this time, with
the potential for flooding of roadways and low lying spots.

It is especially important to not focus on the central track for
this system, as impacts will likely extend far to the east of the
center. All interests in the Florida Keys should continue to
closely monitor the latest forecast updates from the National
Hurricane Center and your National Weather Service office in Key
West during the next several days.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not expected at this time.
