DISCUSSION AND OUTLOOK
----------------------
At 700 PM CDT (0000 UTC), the disturbance was centered near latitude
23.3 North, longitude 94.6 West. The system is moving toward the
northeast near 9 mph (15 km/h). 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.

Data from an Air Force Reserve Hurricane Hunter aircraft indicate
that the maximum sustained winds remain 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.
