The Charleston Police Department has issued a warning for moderate to major coastal flooding throughout the city. The event is driven by incoming king tides expected to impact the area from this weekend through midweek.
Why it matters
Rising water levels during high tide present significant risks to local infrastructure and daily travel. Authorities are cautioning residents that low-lying roads and intersections may become completely impassable.
Official alerts warn of moderate to major coastal flooding as king tides coincide with peak high water levels. Current projections indicate that low-lying infrastructure remains at high risk of becoming impassable through Wednesday.

Seasonal Patterns
This event follows the established pattern of coastal flooding caused by the annual Charleston King Tide season. Such events reflect standard seasonal astronomical cycles that consistently impact the city’s low-lying infrastructure.
Residents should avoid driving through flooded areas, as low-lying roads may quickly become impassable during high tide cycles. It is recommended that motorists plan alternative routes ahead of morning commutes during the warning period.
The takeaway
Always monitor local alerts when king tides are active to ensure safe passage through flood-prone areas. Planning ahead by checking tide charts can help residents avoid becoming stranded in impassable streets.
