Persistent onshore winds coupled with the monthly spring tides led to the highest tides in decades Tuesday morning along the South Carolina and Georgia coasts, driving coastal flooding into Charleston, South Carolina, among other areas.

At least 20 homes, including two businesses, were damaged by the high water at Edisto Beach, South Carolina, according to a local storm report from the National Weather Service.
Coastal flooding closed several streets and intersections on the Charleston peninsula Tuesday morning, according to the Charleston Police Department.
Tide levels at Charleston's harbor topped out at 8.686 feet above mean lower low water level, the location's fourth highest tide on record, dating to 1921.
Only three events produced higher tides at Charleston Harbor: Hugo on Sep. 21, 1989 (12.56 feet), an August 11, 1940 hurricane (10.27 feet) and a New Year's Day 1987 coastal storm (8.84 feet) produced higher tides at Charleston Harbor.
Tuesday's tide level was 4-5 inches higher than the peak measured during the historic South Carolina flooding and coastal flooding event earlier in October. Fortunately this time, there wasn't 17-27 inches of rainfall occurring at the same time.
