DISCUSSION AND OUTLOOK
----------------------
At 100 PM CDT (1800 UTC), the center of Tropical Storm Claudette was
located near latitude 31.8 North, longitude 88.6 West. Claudette is
moving toward the north-northeast near 14 mph (22 km/h).  A turn
toward the northeast is expected later today, followed by a motion
toward the east-northeast tonight or Sunday.  On the forecast track,
the system should move farther inland across portions of the 
southeast U.S. through Sunday night, and over the western Atlantic 
Ocean on Monday.
 
Maximum sustained winds are near 40 mph (65 km/h) with higher 
gusts.  Claudette is expected to weaken to a tropical depression 
later today, however, Claudette is forecast to become a tropical 
storm again when it moves across the Carolinas Sunday night or 
early Monday.
 
Tropical-storm-force winds extend outward up to 205 miles (335 km)
southeast of the center.
 
The estimated minimum central pressure based on surface
observations is 1007 mb (29.74 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
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
www.hurricanes.gov/graphics_at3.shtml?key_messages.
 
RAINFALL: Claudette is expected to produce rainfall totals of 5 to
10 inches with isolated maximum amounts of 15 inches across portions
of coastal Mississippi and Alabama, and the western Florida
Panhandle through the afternoon. Considerable flash, urban and
small stream flooding impacts as well as new and renewed minor to
isolated moderate river flooding are likely across these areas.
 
As the system continues to lift northeast through the weekend, heavy
rain will occur across central Alabama, central and northern
Georgia, and into the Piedmont of the Carolinas, resulting in
rainfall totals of 3 to 6 inches with isolated maximum amounts of 8
inches.  Flash, urban, small stream and isolated minor river
flooding impacts are possible.
 
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...
 
MS/AL Border to Okaloosa/Walton County Line, FL...2-3 ft
Mobile Bay...2-3 ft
Okaloosa/Walton County Line, FL to Panama City, FL...1-2 ft
Pensacola Bay, Choctawhatchee Bay, Saint Andrew Bay...1-2 ft

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 should continue along the coast in
the warning area for a couple of more hours.  Tropical storm 
conditions are possible in the watch area Sunday night and Monday.
 
TORNADOES: A few tornadoes are possible today and tonight across
southeast Alabama, the western Florida Panhandle, and southwest
Georgia.
