DISCUSSION AND OUTLOOK
At 400 AM CDT (0900 UTC), the center of Tropical Depression
Claudette was located near latitude 33.3 North, longitude 85.8 West.
The depression is moving toward the east-northeast near 13 mph (20
km/h). On the forecast track, the system should cross portions of
the southeast U.S. through tonight, move over the coasts of
North Carolina into the western Atlantic Ocean on Monday, and be
located south of Nova Scotia by late Tuesday.
Maximum sustained winds remain near 30 mph (45 km/h) with higher
gusts. Some re-strengthening is expected by late today, and
Claudette is expected to become a tropical storm again on 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
1006 mb (29.71 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 http://www.hurricanes.gov .
RAINFALL: Claudette is expected to produce additional rainfall
totals of 1 to 3 inches with isolated maximum amounts of 6 inches
across Alabama, the Florida Panhandle, northern and central Georgia,
and Upstate South Carolina through the morning hours. As the system
tracks north and east, bands of heavy rain will occur across
portions of central and southern Georgia, central and coastal South
Carolina into eastern North Carolina through Monday morning
resulting in rainfall totals of 2 to 4 inches with isolated maximum
amounts of 8 inches. Considerable flash, urban and small stream
flooding impacts, as well as new and renewed minor to isolated
moderate river flooding are possible across these areas.
Storm total rainfall of 5 to 10 inches with isolated 15 inch amounts
was observed in southeast Louisiana, southern Mississippi, southern
Alabama, and the western Florida panhandle.
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.
