Tropical Weather Statement
Issued: 3:32 AM Jul. 6, 2025 – National Weather Service
This product covers southeast South Carolina and southeast Georgia **CHANTAL STRENGTHENING AS IT DRAWS CLOSER TO THE SOUTH CAROLINA COAST** NEW INFORMATION --------------- * CHANGES TO WATCHES AND WARNINGS: - None * CURRENT WATCHES AND WARNINGS: - A Tropical Storm Watch is in effect for Charleston * STORM INFORMATION: - About 70 miles east of Charleston SC - 32.7N 78.8W - Storm Intensity 50 mph - Movement North or 350 degrees at 8 mph SITUATION OVERVIEW ------------------ Tropical Storm Chantal continues to gradually strengthen as it moves northward toward the South Carolina coast. The center of Chantal is forecast to move onshore north of the Santee River early Sunday morning. Through the overnight, Chantal will produce a few limited impacts across southeast South Carolina, primarily along the coast. Gusty winds will continue to occur along the Charleston County coast, especially from around Charleston to McClellanville. Also, clusters of rain showers will continue to pass through the area, with the bulk of the activity being limited to eastern Berkeley and upper Charleston counties. Additional rainfall amounts of up to an inch will be possible in these areas. Finally other coastal hazards will persist including an elevated risk of rip currents, high surf with breaking waves of 4 to 6 feet, and beach erosion. POTENTIAL IMPACTS ----------------- * WIND: Potential impacts from the main wind event are now unfolding across coastal Charleston County. Remain well sheltered from hazardous wind having limited impacts. If realized, these impacts 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: Potential impacts from the flooding rain are still unfolding across eastern Berkeley County and upper Charleston County. Remain well guarded against locally hazardous flood waters having limited impacts. If realized, these 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: High surf will continue along the Charleston County coast. Also, an elevated risk of rip currents will persist along the entire southeast South Carolina and southeast Georgia coast. PRECAUTIONARY/PREPAREDNESS ACTIONS ---------------------------------- * OTHER PREPAREDNESS INFORMATION: Closely monitor weather.gov, NOAA Weather Radio and local news outlets for official storm information. Listen for possible changes to the forecast. * ADDITIONAL SOURCES OF INFORMATION: - For information on appropriate preparations see ready.gov - For information on creating an emergency plan see getagameplan.org - For additional disaster preparedness information see redcross.org NEXT UPDATE ----------- The next local statement will be issued by the National Weather Service in Charleston SC around 5 AM EDT, or sooner if conditions warrant.
