DISCUSSION AND OUTLOOK
----------------------
At 1100 AM EDT (1500 UTC), the center of Tropical Depression
Claudette was located near latitude 33.8 North, longitude 84.2 West.
The depression is moving toward the east-northeast near 17 mph (28
km/h).  An east-northeastward to northeastward motion with some 
increase in forward speed is expected over the next couple of days. 
On the forecast track, the system should continue to move across 
portions of the southeastern U.S. through tonight, move over the 
coast of North Carolina into the western Atlantic Ocean on Monday, 
and pass near or just south of Nova Scotia on Tuesday.
 
Maximum sustained winds remain near 30 mph (45 km/h) with higher 
gusts.  Some re-strengthening is expected tonight, and Claudette is 
forecast to become a tropical storm again late tonight or early 
Monday over eastern North Carolina.  Further strengthening is 
possible over the western Atlantic Ocean through early Tuesday.  
Claudette is expected to become a post-tropical cyclone by late 
Tuesday.
 
The estimated minimum central pressure from surface observations is 
1009 mb (29.80 inches).

Key messages for Claudette can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT3, WMO header WTNT43 KNHC,
and on the web at

RAINFALL:  Claudette is expected to produce additional rainfall
totals of 2 to 4 inches with isolated maximum totals of 6 inches
across the eastern portions of the Florida Panhandle into North
Florida, southern Georgia, central and coastal South Carolina into
eastern North Carolina through Monday morning.  Flash, urban and
small stream flooding impacts, as well as new and renewed minor

WMO header ACUS43 KWBC or at the following link:
https://www.wpc.ncep.noaa.gov/discussions/nfdscc3.html
 
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...
 
NC/VA Border to Cape Lookout, NC...1-3 ft
Cape Lookout, NC to Little River Inlet, SC...1-2 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 begin in the
warning area late tonight or early Monday.  Tropical storm
conditions are possible in the watch area tonight and Monday.
 
TORNADOES:  A few tornadoes are possible today across parts of
Georgia and the Carolinas.
