Charleston will reach about 77 degrees Thursday under mostly sunny skies, but coastal residents and beachgoers face more immediate concerns than the pleasant afternoon forecast. A coastal flood advisory is in effect through noon, while dangerous rip currents are expected along area beaches through Thursday evening.
Coastal Flooding Peaks Around High Tide
The National Weather Service in Charleston has a coastal flood advisory in effect from 8 a.m. to noon Thursday along shorelines and tidal waterways. High tide is expected around 10:52 a.m., with flooding possible one to two hours before and after high tide.
Some roads could become impassable, and minor flooding of properties is possible in low-lying areas. Drivers should not go around barricades or attempt to cross water of unknown depth, especially near tidal waterways and coastal roads.
Beach Conditions Stay Dangerous
A high risk of rip currents continues through Thursday evening, supported by northeast winds and long-period swells. The weather service advises swimmers to stay near lifeguards; anyone caught in a rip current should relax, float and move parallel to the shoreline rather than trying to swim directly against the current.
Sunny Friday Before Clouds And Rain Chances
Thursday night will be partly cloudy with a low around 62 degrees, followed by a sunny Friday with another high near 77. Northeast winds will ease somewhat Friday, but Saturday turns mostly cloudy with a high near 75 and gusts that could reach 30 mph.
Clouds will linger Saturday night, with rain chances increasing late in the weekend and into early next week. Charleston’s rain chance is 20% Sunday, 40% Sunday night and 40% Monday, while temperatures remain mild with highs in the mid-70s. Tuesday should be partly sunny near 77 degrees, with another small shower chance possible Wednesday afternoon.
