Charleston, SC – Coastal communities across southeastern South Carolina and southeastern Georgia face another round of moderate tidal flooding Wednesday morning, Oct. 28, with up to 1 foot of saltwater inundation possible and some roads potentially becoming impassable during the morning commute.
According to the National Weather Service in Charleston, a Coastal Flood Advisory is in effect as elevated tides threaten low lying coastal roads and properties along portions of both states' shorelines.
High Tide Near 10 AM Brings Flooding Threat The NWS expects high tide around 10 a.m. Wednesday, with coastal flooding possible one to two hours before and after peak high tide.
That places the primary flooding window between approximately 8 a.m. and noon, potentially affecting morning travel, deliveries and access to waterfront neighborhoods.
Saltwater inundation of up to 1 foot could cover vulnerable roads, intersections and parking areas, particularly locations that frequently experience tidal flooding.
Roads Could Become Impassable The advisory covers portions of the southeastern South Carolina coastline and extends southward into coastal Georgia.
Communities in the Charleston coastal region and along the Georgia shoreline should remain alert for changing road conditions.
The NWS warns that some roads could become impassable, while minor flooding of properties is also possible.
Motorists should avoid driving through standing water, even when the depth appears manageable. Saltwater flooding can conceal roadway hazards and create dangerous driving conditions.
Drivers are also urged to obey road closure barricades and use alternate routes when necessary.
Flooding Expected Around Morning High Tide Unlike flooding caused by heavy rainfall, this event is associated with elevated coastal water levels during high tide.
Conditions may improve as tides recede, although water could linger in poorly drained locations.
Residents and commuters should monitor local road closures and updated National Weather Service advisories throughout Wednesday morning.
