3. Tropical storm conditions are expected along portions of theNorth Carolina coast late tonight and Monday, where a Tropical StormWarning is in effect. Tropical storm conditions are possible innortheastern South Carolina tonight and Monday, where a TropicalStorm Watch is in effect.

CHANGES WITH THIS ADVISORY:

None.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Tropical Storm Warning is in effect for...
- Little River Inlet to Duck, North Carolina
- Pamlico and Albemarle Sounds

A Tropical Storm Watch is in effect for...
- South Santee River, South Carolina to Little River Inlet

A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area, in this case within 24 to 36 hours.

A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, in this case within the next 24 to 36 hours.

Interests elsewhere across the Carolinas should monitor the progress of this system.

For storm information specific to your area, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office.

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: Through Monday morning, Claudette is expected to produce additional rainfall totals of 1 to 3 inches with isolated maximum totals of 5 inches across portions of southeastern Georgia, central and coastal South Carolina, and southcentral to eastern North Carolina. Flash, urban and small stream flooding impacts, as well as isolated minor river flooding are possible across these areas.

For the latest rainfall reports and wind gusts associated with Claudette, see the companion storm summary at WBCSCCNS3 with the 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...13 ft Cape Lookout, NC to Little River Inlet, SC...12 ft

Surgerelated 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: Isolated tornadoes are possible this evening across parts of the central and eastern Carolinas.

At 800 PM EDT (0000 UTC), the center of Tropical Depression Claudette was located near latitude 34.4 North, longitude 81.3 West. The depression is moving toward the eastnortheast near 17 mph (28 km/h). An eastnortheastward 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 restrengthening is expected tonight, and Claudette is forecast to become a tropical storm again late tonight or early Monday over eastern North Carolina. Some additional strengthening is possible over the western Atlantic Ocean through early Tuesday. Claudette is expected to become a posttropical cyclone Tuesday afternoon or Tuesday night.

The estimated minimum central pressure from surface observations is 1008 mb (29.77 inches).

Satellite and surface observations show that Claudette's circulationhas become elongated today and that there is a fairly large area oflight winds near the center. Observations along the southeasternU.S. coast and over coastal sections of the Carolinas indicate thatthe winds have increased somewhat but these data still support aninitial intensity of 25 kt. As Claudette approaches the coast overnight and Monday morning, restrengthening is anticipated, and the cyclone is forecast to regain tropical storm status before it exits the coast of North Carolina. Some additional strengthening is forecast while Claudette moves over the warm waters of the Gulf Stream and the shear remains low. The system should become extratropical Tuesday afternoon when it passes near Nova Scotia, and the global models indicate that it will degenerate into a trough of low pressure by Wednesday morning. The NHC intensity foreast is close to the intensity model consensus and follows the trends of the various global models.

The depression is moving east-northeastward at around 15 kt. Amid-latitude trough that is moving into the central United Statesshould continue to steer Claudette east-northeastward tonortheastward over the next couple of days. The center of Claudetteis forecast to move offshore of the coast of North Carolina Mondaymorning, then pass well offshore of the Mid-Atlantic coast Mondaynight, and be near or just southeast of Nova Scotia on Tuesday.The dynamical model guidance remains in very good agreement and theNHC forecast again lies near the various consensus aids.
