Charleston, SC
The National Weather Service (NWS) in Charleston has issued a coastal flood advisory for Coastal Jasper and Beaufort County, set to remain in effect from 8 a.m. to 11 a.m. on Wednesday. Residents in these areas can expect up to half a foot of inundation above ground level, particularly along shorelines and tidal waterways near Fort Pulaski.
High tide is predicted to occur around 9:21 a.m. today, leading to potential saltwater inundation both before and after this time. Residents are advised that roads may be impacted by the rising saltwater, and they should prepare for travel delays as some roads may be closed. It is essential for individuals to avoid driving around barricades or through water of unknown depth, and to take necessary precautions to protect flood-prone properties.
The advisory remains in effect until 11 a.m., urging residents in flood-prone areas to consider moving to higher ground. In the event that evacuation is required, individuals should do so immediately, securing their homes and disconnecting utilities if time permits. Avoidance of basements and rooms with submerged electrical outlets is also highly recommended, as any unusual sparks or noises should prompt an immediate cease of operations in those areas.
Heavy rains heighten the risk of flooding, especially in low-lying areas, where even 6 inches of swiftly moving water can knock individuals off their feet. Moreover, driving through flooded roads is discouraged; as little as 12 inches of rapid water can sweep most vehicles away. Hydroplaning, a condition where vehicles lose traction due to water accumulation, may also result in loss of control while driving.
In addition to local advisories, the NWS Newport/Morehead City, NC has issued a coastal flood advisory from Thursday 7 a.m. until Monday 8 a.m. for Southern Craven, Beaufort, and Pamlico counties. Expected inundation levels in these areas range from 1 to 2 feet, with a strong coastal storm developing off the North Carolina coast likely to lead to increased winds and water levels over the weekend.
Many regions are currently bracing for extreme tidal conditions, with alerts spanning from the Carolinas down to Florida. Coastal flooding has already been reported in various locations along the East Coast due to seasonal King Tides coinciding with a Supermoon and persistent onshore winds. Notably, nine homes in North Carolina’s Outer Banks collapsed into the Atlantic Ocean amid large waves exacerbated by recent hurricanes. Reports from Bluffton, South Carolina indicate significant flooding attributable to King Tide events.
As a result of these conditions, flooding is anticipated in low-lying properties, including parking lots and homes adjacent to water. Video evidence shared by meteorologists illustrates the extensive flooding and damage across affected areas.
The NWS has indicated that these conditions are expected to persist through early next week, with gradual improvement anticipated mid- to late-week. The gravitational pull from the Supermoon is responsible for the extreme high tides known as King Tides, suggesting further coastal alerts may be forthcoming throughout the season.
