With an 8.7-foot tide forecast for Sunday morning—potentially the third highest non-tropical high tide since 1934—City of Charleston emergency management officials urge residents and visitors to prepare for major tidal flooding. The National Weather Service is forecasting high tides at and well above 8.0 feet into the weekend and through Monday morning’s predicted 8.5’ high tide.
Motorists should plan their travel and avoid driving in areas prone to tidal flooding around the time of high tide. Cars can stall from driving or parking in flooded areas.
Saturday’s high tides occur at 10:07 a.m. and 10:23 p.m. High tides on Sunday come at 11:01 a.m. and 11:15 p.m. Monday morning’s high tide is at 11:57 a.m. Flooding can occur 1-2 hours before and after the peak of high tide. Fortunately, the chance of rain is low this weekend, according to the National Weather Service.
The extreme flooding could make more roads impassable than usual, strand motorists and stall cars, delay emergency services, and affect some properties.
City police are monitoring conditions and will work with city Traffic and Transportation to manage road closures and re-openings as conditions warrant.
