SUMMARY OF 800 AM EDT...1200 UTC...INFORMATION ---------------------------------------------- LOCATION...36.4N 76.3W ABOUT 15 MI...25 KM W OF DUCK NORTH CAROLINA ABOUT 30 MI...50 KM S OF NORFOLK VIRGINIA MAXIMUM SUSTAINED WINDS...40 MPH...65 KM/H PRESENT MOVEMENT...ENE OR 65 DEGREES AT 28 MPH...45 KM/H MINIMUM CENTRAL PRESSURE...1007 MB...29.74 INCHES WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: The Tropical Storm Warning for eastern North Carolina has been discontinued. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: There are no coastal watches or warnings in effect. DISCUSSION AND OUTLOOK ---------------------- At 800 AM EDT (1200 UTC), the center of Tropical Storm Claudette was located near latitude 36.4 North, longitude 76.3 West. Claudette is moving toward the east-northeast near 28 mph (45 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 will cross into the western Atlantic Ocean later this morning, and pass just south of Nova Scotia on Tuesday. Maximum sustained winds remain near 40 mph (65 km/h) with higher gusts. These winds are occurring mostly over water,southeast of Claudette's center. Some additional slight strengthening is possible over the western Atlantic Ocean today. Claudette is forecast to become a post-tropical cyclone Tuesday afternoon and dissipate late Tuesday night. Tropical-storm-force winds extend outward up to 140 miles (220 km) from the center in the southeastern quadrant. 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: An additional 1 to 2 inches of rain is expected across far eastern North Carolina over the next few hours. Isolated flash, urban, and small stream flooding impacts are possible. 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 NEXT ADVISORY ------------- Next complete advisory at 1100 AM EDT. $$ Forecaster Stewart

Tropical Storm Claudette Forecast Discussion Number 15
2021-06-21 10:42:00| National Hurricane Center (Atlantic)
Issued at 500 AM EDT Mon Jun 21 2021 000 WTNT43 KNHC 210841 TCDAT3 Tropical Storm Claudette Discussion Number 15 NWS National Hurricane Center Miami FL AL032021 500 AM EDT Mon Jun 21 2021 The elongated low-level center of Claudette is located over eastern North Carolina this morning, while a curved band of convection continues pushing eastward across the adjacent coastal and offshore waters. Surface pressures have fallen slightly overnight near the estimated center position, and Frying Pan Shoals buoy 41013 off the coast of southeastern North Carolina reported a brief period of sustained tropical-storm-force winds shortly after 06 UTC. Therefore, Claudette's initial intensity is raised to 35 kt with this advisory, making it a tropical storm once again. Claudette continues to accelerate east-northeastward as it is steered by a mid- to upper-level trough that is approaching the eastern United States. The storm will move off the North Carolina coast within the next few hours, and a bit more strengthening is possible today as it passes near the north wall of the Gulf Stream. The official NHC forecast hangs onto Claudette as a tropical cyclone through tonight, then quickly transitions it to a post-tropical cyclone by 36 h. The time of dissipation is also moved up a day earlier with this advisory, which is consistent with the latest global model fields that show an open trough approaching Atlantic Canada. Otherwise, the official NHC forecast remains very similar to the previous one, and the track closely follows the multi-model consensus. Some of the global guidance suggests that Claudette could lose its closed low-level circulation and open up into a trough soon after emerging into the western Atlantic Ocean later today. Given the current poor center definition, it is a plausible alternative scenario that Claudette dissipates faster than shown below. Key Messages: 1. Heavy rain from Claudette will continue over the North Carolina coast this morning. Isolated flash, urban, and small stream flooding impacts are possible. 2. Tropical storm conditions are expected along portions of the North Carolina coast through this morning, where a Tropical Storm Warning is in effect.

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.
