Charleston, South Carolina barely saw a quarter of an inch of rain on Tuesday. So how is it that roads were covered in water and bridges were impassible? The King Tide.

Every year, the highest seasonal tides are referred to as “King Tides.” Average high tide in Charleston is usually around 5.5 feet. On Tuesday morning, the Charleston Harbor Tide Gage peaked at 8.69 feet. That is the fourth highest level ever recorded at this station. Flood Stage is only seven feet. Water on roads brought rush hour traffic to a screeching halt. Flooding closed roads in Mount Pleasant, James Island, West Ashley, and Isle of Palms. Water seeped into downtown homes and businesses that are still cleaning up from similar flooding earlier in the month.

Coastal flooding wasn’t confined to just South Carolina. Northeast winds and a full moon close to Earth drove up water levels up and down the southeast coast. Near Savannah, Georgia at the Fort Pulaski Tide Gage, water levels reached the third highest measurement ever on Tuesday. Even Miami, Florida has seen near record levels in the past month.

Tides ran higher than normal into Wednesday morning. Conditions will improve through the week, allowing coastal flood advisories and watches to expire.
