The gauge indicates that the tide reached 8 feet, the minimum level for a major flood, for a few minutes around 9 a.m.
Saturday morning’s tide should be even higher.
Joey Sovine of WCSC Affiliate tweeted, “This is the highest tide since December 16, 2020. We are starting to see street closures increase in downtown Charleston.”
Street flooding nearly a foot deep was reported near Charleston Harbor by the National Weather Service. Low, flood-prone roads were closed in Charleston and nearby towns.
Further south, a tide gauge at Fort Pulaski — near Savannah, Georgia — reached 10 feet, just before major flood stage Friday morning.
Although receding now, the tide is expected to reach major flood stage (10.5 feet) Saturday morning.
“Only about 3% of all flood tides reach this level in Charleston, and even less frequently in Fort Pulaski,” the National Weather Service in Charleston said.
Low roads were closed around the area near the Fort Pulaski gauge.
“We are particularly concerned about the only in and out road – which runs from Savannah to Tybee Island. The road was raised a few years ago, but at 10.5 feet we expect problems there- low,” Ron Morales, a meteorologist with the National Weather Service in Charleston, told CNN Weather on Wednesday.
Coastal flood warnings and advisories are spreading along the coast as the presence of higher than normal tides, known as “king tides”, are compounded by the climate crisis and a developing storm system to the south.
