WTUS82 KCHS 051200 HLSCHS SCZ042>045-047>052-052000- Tropical Storm Chantal Local Statement Intermediate Advisory Number 3A National Weather Service Charleston SC AL032025 800 AM EDT Sat Jul 5 2025 This product covers southeast South Carolina and southeast Georgia **CHANTAL TO APPROACH THE SOUTH CAROLINA COAST SUNDAY MORNING** NEW INFORMATION --------------- * CHANGES TO WATCHES AND WARNINGS: - None * CURRENT WATCHES AND WARNINGS: - A Tropical Storm Watch is in effect for Charleston * STORM INFORMATION: - About 140 miles south-southeast of Charleston SC - 30.9N 79.0W - Storm Intensity 40 mph - Movement North or 005 degrees at 2 mph SITUATION OVERVIEW ------------------ Tropical Storm Chantal will meander towards the South Carolina coast today and tonight before making landfall along the middle and upper South Carolina coast Sunday morning. As Chantal nears the coast, breezy northwest winds will occur as the system interacts with high pressure to the north. Wind gusts are forecast to remain the strongest along the South Carolina beaches, with gusts around 40 mph possible. In addition, wind gusts across the elevated bridges around the Charleston Metro area may exceed 45 mph at times today. Rain bands will push onshore along the coast of the South Carolina Lowcountry this morning and continue into tonight. These bands may drift slowly inland as the system nears the coast bringing as much as 1 to 2 inches of rain. The rain may become locally heavy at times, resulting in flooding, mainly in low-lying and poor drainage areas. Heavy rainfall could occur during the late afternoon high tide, potentially increasing the risk of flooding across coastal communities and locations near tidal waterways late this afternoon into early this evening. This includes Downtown Charleston. Widespread flash flooding is unlikely at this time. Gusty winds and building waves will result in strong rip currents along the South Carolina and Georgia coast through this weekend. In addition, beach erosion and high surf with breakers of 4 to 6 feet could occur along the beaches of Charleston County. POTENTIAL IMPACTS ----------------- * WIND: Prepare for hazardous wind having possible limited impacts across Charleston County. Potential impacts in this area include: - Damage to porches, awnings, carports, sheds, and unanchored mobile homes. Unsecured lightweight objects blown about. - Large tree limbs broken off. A few trees snapped or uprooted, but with greater numbers in places where trees are shallow rooted. - Some roads impassable due to debris, particularly within urban or heavily wooded locations. Hazardous driving conditions on bridges and other elevated roadways, especially for high profile vehicles. - Isolated to scattered power and communications outages. Elsewhere across southeast South Carolina and southeast Georgia, little to no impact is anticipated. * FLOODING RAIN: Prepare for locally hazardous rainfall flooding having possible limited impacts across the South Carolina Lowcountry. Potential impacts include: - Localized rainfall flooding could prompt a few rescues. - Rivers and tributaries could quickly rise with swifter currents. Small streams, creeks, canals, and ditches could become swollen and overflow in spots. - Flood waters can enter a few structures, especially in normally vulnerable spots. Rapid ponding of water could occur at underpasses, low-lying spots, and poor drainage areas. Several storm drains and retention ponds become near-full and begin to overflow. Some brief road and bridge closures. Elsewhere across southeast South Carolina and southeast Georgia, little to no impact is anticipated. * OTHER COASTAL HAZARDS: Gusty winds and increasing wave activity will result in strong rip currents and high surf along the South Carolina and Georgia coasts through this weekend.
