Tropical Storm Chantal is set to bring potentially damaging winds to coastal South Carolina, particularly impacting the Charleston and Colleton County shorelines by early Sunday. Residents in these areas should prepare for stormy conditions, including strong wind gusts and possible power outages.
Tropical Storm Impact for Charleston, SC
The National Weather Service in Charleston reports that wind gusts along the coast could reach up to 35 mph, with some isolated areas near Highway 17 and Interstate 526 potentially experiencing gusts exceeding 45 mph. Chantal is expected to make landfall by Sunday morning, and as the storm strengthens, wind speeds may increase, making conditions even more hazardous.
Risks to Coastal Communities
Charleston, Colleton County, and other Lowcountry areas should be prepared for scattered power outages, hazardous travel, and possible debris. Travel over bridges, especially during peak wind gust periods, will be particularly dangerous. Residents are advised to secure outdoor items, stay indoors when winds are strongest, and avoid unnecessary travel.
Marine Conditions and Offshore Risks
Offshore, wind gusts could exceed 50 knots near the storm’s center, which will make marine conditions extremely dangerous. Fishermen, boaters, and anyone planning to be on the water should avoid marine activities until conditions improve. The storm’s intensity may also create rough waters, making it unsafe for watercraft.
First Tropical System of 2025 Hurricane Season
This is the first tropical system to directly affect South Carolina during the 2025 Atlantic hurricane season. As of Saturday afternoon, the greatest wind threat remains concentrated along the immediate coastline, with breezy conditions likely extending inland. Though inland areas may not experience the full force of the storm, residents should still be prepared for gusty winds and rain.
