Issued at 800 PM EDT Sun Jun 20 2021 000 WTNT33 KNHC 202344 TCPAT3 BULLETIN Tropical Depression Claudette Intermediate Advisory Number 13A NWS National Hurricane Center Miami FL AL032021 800 PM EDT Sun Jun 20 2021 ...CLAUDETTE EXPECTED TO RE-STRENGTHEN BEFORE IT EXITS THE COAST OF NORTH CAROLINA... SUMMARY OF 800 PM EDT...0000 UTC...INFORMATION ---------------------------------------------- LOCATION...34.4N 81.3W ABOUT 25 MI...50 KM NNW OF COLUMBIA SOUTH CAROLINA ABOUT 190 MI...310 KM WNW OF CAPE FEAR NORTH CAROLINA MAXIMUM SUSTAINED WINDS...30 MPH...45 KM/H PRESENT MOVEMENT...ENE OR 70 DEGREES AT 17 MPH...28 KM/H MINIMUM CENTRAL PRESSURE...1008 MB...29.77 INCHES WATCHES AND WARNINGS -------------------- 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. DISCUSSION AND OUTLOOK ---------------------- 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 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. Some additional strengthening is possible over the western Atlantic Ocean through early Tuesday. Claudette is expected to become a post-tropical cyclone Tuesday afternoon or Tuesday night. The estimated minimum central pressure from surface observations is 1008 mb (29.77 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: 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 south-central 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...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: Isolated tornadoes are possible this evening across parts of the central and eastern Carolinas. NEXT ADVISORY ------------- Next complete advisory at 1100 PM EDT. $$ Forecaster Pasch

Tropical Depression Claudette Forecast Discussion Number 13
2021-06-20 22:32:10| National Hurricane Center (Atlantic)
Issued at 500 PM EDT Sun Jun 20 2021 000 WTNT43 KNHC 202032 TCDAT3 Tropical Depression Claudette Discussion Number 13 NWS National Hurricane Center Miami FL AL032021 500 PM EDT Sun Jun 20 2021 Satellite and surface observations show that Claudette's circulation has become elongated today and that there is a fairly large area of light winds near the center. Observations along the southeastern U.S. coast and over coastal sections of the Carolinas indicate that the winds have increased somewhat but these data still support an initial 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. A mid-latitude trough that is moving into the central United States should continue to steer Claudette east-northeastward to northeastward over the next couple of days. The center of Claudette is forecast to move offshore of the coast of North Carolina Monday morning, then pass well offshore of the Mid-Atlantic coast Monday night, and be near or just southeast of Nova Scotia on Tuesday. The dynamical model guidance remains in very good agreement and the NHC forecast again lies near the various consensus aids. Key Messages: 1. Claudette is expected to produce heavy rainfall and flash flooding from North Florida and southeastern Georgia into the Carolinas through Monday morning. Flash, urban, and small stream flooding impacts are possible across these areas. 2. Isolated tornadoes are possible this evening across parts of the central and eastern Carolinas. 3. Tropical storm conditions are expected along portions of the North Carolina coast late tonight and Monday, where a Tropical Storm Warning is in effect. Tropical storm conditions are possible in northeastern South Carolina tonight and Monday, where a Tropical Storm Watch is in effect.
