DISCUSSION AND OUTLOOK
----------------------
At 700 AM CDT (1200 UTC), satellite imagery, NOAA Doppler weather
radar data, and surface observations indicate that the center of
Tropical Storm Nestor has redeveloped farther west near latitude
29.5 North, longitude 86.8 West. Nestor is moving toward the
northeast near 17 mph (28 km/h). Some erratic motion toward the
northeast or east-northeast is expected through this morning. A turn
toward the east-northeast is forecast to occur Sunday. On the
forecast track, Nestor will move inland over the Florida Panhandle
late this morning or early afternoon, and will then move across
portions of the southeastern United States later today and Sunday
as a post-tropical cyclone. Nestor is expected to move offshore of
the coast of North Carolina into the western Atlantic by late
Sunday also as a post-tropical cyclone.
Doppler radar data and surface observations indicate that maximum
sustained winds remain near 50 mph (85 km/h) with higher gusts. No
change in strength is anticipated before Nestor reaches the coast,
but weakening is forecast to begin after the cyclone moves inland.
Nestor is expected to lose tropical characteristics and become
post-tropical by early afternoon.
Tropical-storm-force winds extend outward up to 160 miles (260 km)
mainly to the east of the center. The Tyndall AFB Tower located
south of Apalachicola, Florida, recently reported a sustained wind
of 49 mph (80 km/h) and a gust to 61 mph (98 km/h) at an elevation
of 115 ft (35 m).
A National Ocean Service tide gauge at Apalachicola, Florida,
recently measured a water level of 3.2 ft above Mean Higher High
Water.
The minimum central pressure based on nearby surface observations
is estimated to be 996 mb (29.41 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
Tampa Bay...1 to 3 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 reach or are
already reaching the coast within the warning area, and will
continue through this afternoon.
Gale-force winds are likely to begin along portions of the Atlantic
coast of the southeastern United States later today.
RAINFALL: Nestor is expected to produce total rainfall accumulations
of 2 to 4 inches this weekend across portions of the southeastern
United States, with isolated maximum amounts of 8 inches.
TORNADOES: A few tornadoes are possible through midday in
the northern and central Florida Peninsula, and later today and
tonight over coastal areas of Georgia and the Carolinas.
