SUMMARY OF 200 AM EDT...0600 UTC...INFORMATION ---------------------------------------------- LOCATION...30.6N 78.8W ABOUT 165 MI...265 KM SSE OF CHARLESTON SOUTH CAROLINA ABOUT 255 MI...410 KM SSW OF WILMINGTON NORTH CAROLINA MAXIMUM SUSTAINED WINDS...35 MPH...55 KM/H PRESENT MOVEMENT...STATIONARY MINIMUM CENTRAL PRESSURE...1010 MB...29.82 INCHES WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: None. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Watch is in effect for... * Edisto Beach to Little River Inlet A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. Interests elsewhere along the southeast coast of the United States should monitor the progress of this system. Additional warnings and watches will likely be required for portions of this area later today. 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 200 AM EDT (0600 UTC), the center of Tropical Depression Three was located near latitude 30.6 North, longitude 78.8 West. The depression has been nearly stationary tonight, but a slow motion towards the north-northwest is expected to begin later today, followed by a motion toward the north by the end of the day, and then northeast by Sunday night. On the forecast track, the center of the depression is expected to move near or over the coast of South Carolina on Sunday morning. Maximum sustained winds remain near 35 mph (55 km/h) with higher gusts. Gradual strengthening is expected, and the system is forecast to become a tropical storm later today. The estimated minimum central pressure as measured by a recent ship observation near the center is 1010 mb (29.82 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Tropical Depression Three can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT3 and WMO header WTNT43 KNHC. WIND: Tropical storm conditions are possible in the watch area beginning late today or early Sunday. RAINFALL: Tropical Depression Three is expected to produce heavy rainfall across portions of the coastal plain of the Carolinas today through Monday. Storm total rainfall of 2 to 4 inches, with local amounts to 6 inches, is expected. This would result in an elevated risk for flash flooding. For a complete depiction of forecast rainfall and flash flooding associated with Tropical Depression Three, please see the National Weather Service Storm Total Rainfall Graphic, available at hurricanes.gov/graphics_at3.shtml?rainqpf STORM SURGE: A storm surge of 1 to 2 ft above ground level could occur along the coast in the tropical storm watch area in areas of onshore flow. SURF: The depression is expected to bring rough surf and rip currents to much of the southeastern United States coastline north of northeastern Florida during the next couple of days. A depiction of rip current risk for the United States can be found at: hurricanes.gov/refresh/graphics_at3+shtml/?ripCurrents#contents NEXT ADVISORY ------------- Next complete advisory at 500 AM EDT. $$ Forecaster Papin

Issued at 1100 PM EDT Fri Jul 04 2025 358 WTNT43 KNHC 050235 TCDAT3 Tropical Depression Three Discussion Number 2 NWS National Hurricane Center Miami FL AL032025 1100 PM EDT Fri Jul 04 2025 The depression is less organized on satellite imagery this evening, with a seemingly elongated low-level center near or just west of the deep convection. This structure is due to persistent southwesterly shear, with a mid-level circulation apparent east of the low-level center. The current intensity will remain 30 kt, consistent with data from the last Air Force reconnaissance mission and satellite trends. The system has been moving erratically recently, but a longer term motion is basically stationary. A slow north-northwestward motion is anticipated to begin on Saturday as the depression is steered on the northeast side of a developing mid- to upper-level low over the northeastern Gulf. After that time, the system should be steered to the north and northeast with a gradual increase in forward speed along the western periphery of the subtropical ridge. This motion should bring the center near or over the coast of South Carolina Sunday morning. The new NHC track forecast was nudged to the east, consistent with the latest guidance. The global models generally indicate that the current shear should lessen on Saturday, which could allow for some strengthening in combination with the warm waters of the Gulf Stream. There is plenty of dry air aloft, however, which will probably limit significant development, as well as the current disheveled structure. The bulk of the guidance indicates modest strengthening as the system approaches the coast, and the new forecast follows suit, near the latest model consensus. Key Messages: 1. Tropical storm conditions are possible in the watch area beginning Saturday and continuing through Sunday morning. 2. Heavy rainfall across the coastal Carolinas will cause some flash flooding concerns from Tropical Depression Three between Saturday through Monday. Isolated to scattered flash flooding could occur within more urbanized areas along the coastal plain of the Carolinas. 3. The system is expected to bring rough surf and rip currents to much of southeastern United States north of northeastern Florida during the next couple of days.
