DISCUSSION AND OUTLOOK
----------------------
At 100 AM CDT (0600 UTC), the center of Tropical Depression
Claudette was located near latitude 32.9 North, longitude 86.7 West.
The depression is moving toward the northeast near 13 mph (20 km/h).
A turn toward the east-northeast is expected later today. On the 
forecast track, the system should cross portions of the southeast 
U.S. through Sunday night, and move over the coasts of the 
Carolinas into the western Atlantic Ocean on Monday.
 
Maximum sustained winds remain near 30 mph (45 km/h) with higher
gusts.  These winds are mainly occurring over the Gulf of Mexico
well to the south of the center.  Little change in strength is
expected today.  However, the cyclone is forecast to become a 
tropical storm again when it moves across the Carolinas Sunday 
night or early Monday.
 
The estimated minimum central pressure based on surface
observations is 1006 mb (29.71 inches).

STORM SURGE:  The combination of 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...
 
Cape Lookout, NC to NC/VA Border...1-3 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 possible in the watch area
Sunday night and Monday.
 
TORNADOES: A few tornadoes are possible overnight across southeast
