Flooding prompts road closures in Charleston, South Carolina

Relentless heavy rainfall in Charleston, South Carolina, led to flooding and road closures on Wednesday.

The Charleston Police Department reported multiple street closures throughout the downtown area due to flooding. Officials are warning local drivers to avoid roads downtown as more than 20 streets closed as of 1 p.m., even as the rain let up briefly. Some three dozen streets remained at least partially blocked.

Carriage horses in downtown Charleston were ordered off the streets just before noon Wednesday. The horses were pulled as Charleston police were forced to close streets and quick downpours continued to hit the downtown area.

"It’s no surprise that they flooded because the city is prone to flooding. Any time there is heavy rainfall around high tide there, as happened this morning, there is likely to be flooding," AccuWeather Senior Meteorologist Frank Strait said.

The flooding comes amid heavy rainfall that has fallen throughout the Lowcountry since Tuesday night.

"Charleston’s airport has received 1.78 inches of rain since midnight, most of it coming between 2 a.m. and 7 a.m. High tide this morning was at 4:13 a.m.," Strait said.

"The flooding is especially to occur in Charleston when there is a full or new moon and the high tides are the highest; in fact, minor flooding occurs in Charleston solely due to the highest astronomical tides, which are commonly called King Tides," Strait said.

"Flooding can be widespread and is most serious there when heavy rainfall occurs during a high tide when a King Tide is occurring," Strait said.

Drier weather is in store across Charleston and the remainder of the South through Friday.
