Some downtown Charleston streets could flood again tonight.
The National Weather Service has issued a coastal flood advisory until 11 p.m. for the Charleston area.
High tide is around 9 p.m. in Charleston and will peak around 7 feet, which usually means flooding in low-lying areas, according to the weather service. Flooding is possible an hour before and two hours after high tide.
The weather service is also warning of a slight chance of severe thunderstorms Wednesday. Storms could bring high winds, hail and tornadoes. Even without severe weather, the chance of heavy rain for Wednesday is 50 percent.
