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 hours. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, in this case within 24 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 1100 PM EDT (0300 UTC), the center of Tropical Depression Claudette was located near latitude 34.7 North, longitude 80.4 West. The depression is moving toward the east-northeast near 20 mph (31 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 are near 35 mph (55 km/h) with higher gusts. Some strengthening is expected tonight, and Claudette is forecast to become a tropical storm again by 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 based on 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 by early Monday. Tropical storm conditions are possible in the watch area tonight and Monday. TORNADOES: A couple of tornadoes are possible through early Monday across parts of the coastal Carolinas. NEXT ADVISORY ------------- Next intermediate advisory at 200 AM EDT. Next complete advisory at 500 AM EDT. $$ Forecaster Pasch

Tropical Depression Claudette Forecast Discussion Number 14
Issued at 1100 PM EDT Sun Jun 20 2021000 WTNT43 KNHC 210238 TCDAT3 Tropical Depression Claudette Discussion Number 14 NWS National Hurricane Center Miami FL AL032021 1100 PM EDT Sun Jun 20 2021 Deep convection is increasing in curved bands to the east and northeast of the center, however the center of circulation itself is not very well defined. Coastal surface observations indicate that the highest winds have increased to near 30 kt. Some additional restrengthening is anticipated, and Claudette is expected to regain tropical storm strength prior to moving into the Atlantic on Monday. A little more intensification could occur while the system moves near the northern edge of the Gulf Stream during the next day or so, as reflected in the official forecast. Within 48 hours, as the cyclone moves near Atlantic Canada, the global models suggest that the system will lose tropical characteristics, or even open up into a trough. Claudette's forward speed is gradually increasing and the current motion is estimated to be near 070/17 kt. On the projected track, the system should move into the western Atlantic tomorrow. The flow ahead of a broad 500 mb trough approaching the eastern United States should cause the cyclone to accelerate east- northeastward to northeastward during the next 48 hours. The official forecast is very similar to the previous one, and close to the model consensus TVCN. No changes to the warning and watch along the southeastern United States coasts are required at this time. Key Messages: 1. Claudette is expected to produce heavy rainfall and flash flooding from southeastern Georgia into the Carolinas through Monday morning. Flash, urban, and small stream flooding impacts are possible across these areas. 2. A couple of tornadoes are possible through early Monday across parts of the coastal Carolinas. 3. Tropical storm conditions are expected along portions of the North Carolina coast by early 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.
