DISCUSSION AND OUTLOOK
----------------------
At 400 PM CDT (2100 UTC), the disturbance was centered near latitude
22.9 North, longitude 95.2 West. The system is moving toward the
north-northeast near 9 mph (15 km/h). A turn toward the northeast
is expected tonight, and a northeastward motion at a faster forward
speed is expected on Friday and Saturday. On the forecast track,
the system will approach the northern Gulf Coast Friday and Friday
night and then move over portions of the southeastern United States
on Saturday.

Recent satellite wind data indicates that maximum sustained winds
are now near 40 mph (65 km/h) with higher gusts. The disturbance is
expected to develop into a tropical or subtropical storm later
tonight or on Friday, with slow strengthening then expected through
Friday night.
* Formation chance through 48 hours...high...90 percent
* Formation chance through 5 days...high...90 percent

Tropical-storm-force winds extend outward up to 115 miles (185 km)
mainly to the southwest of the center.

The estimated minimum central pressure is 1005 mb (29.68 inches).


HAZARDS AFFECTING LAND
----------------------
STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline.  The water could
reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide...

Indian Pass FL to Chassahowitzka FL...3 to 5 ft
Chassahowitzka to Clearwater Beach FL...2 to 4 ft

Surge-related flooding depends on the relative timing of the surge
and the tidal cycle, and can vary greatly over short distances.  For
information specific to your area, please see products issued by
your local National Weather Service forecast office.

WIND:  Tropical storm conditions are expected to first reach the
coast within the warning area by Friday afternoon, making outside
preparations difficult or dangerous.

Gale-force winds are possible along portions of the Atlantic coast
of the southeastern United States by Saturday.

RAINFALL: The disturbance is expected to produce total rainfall
accumulations of 2 to 4 inches this weekend from the central Gulf
Coast and northern and central Florida to the eastern Carolinas,
with isolated maximum amounts of 5 inches.
