A combination of seasonal king tides and an offshore storm system threatens to inundate coastal towns, wash out beaches, and snarl regional travel from Florida through South Carolina through the end of the week.

AccuWeather meteorologists warned Monday that steady onshore winds coupled with astronomical high tides will likely cause repeated flooding cycles, heavy surf, and severe rip currents along the Southeast Atlantic shoreline through the end of October.

“Coastal communities, including Miami and Charleston, South Carolina, are vulnerable to multiple rounds of tidal floodings as high astronomical tides associated with the full moon combine with onshore winds pushing ocean water toward the coast,” said AccuWeather expert meteorologist Tyler Roys.

Forecasters expect low-lying streets, docks, and beachfront neighborhoods to see standing water during high tide cycles. Persistent wave activity will also speed up shoreline erosion, while rough sea conditions are projected to cause disruptions across port traffic, cruise operations, marine transport, and beach tourism.

At the same time, forecasters are watching a broad area of low pressure lifting north out of the Caribbean toward the Bahamas. The system carries a low chance of tropical development between Oct. 27 and Oct. 30.

Meteorologists do not expect rapid strengthening. However, slow organization could deliver gusty winds across the Bahamas and the Florida peninsula. Trailing moisture linked to a nearby front could also trigger heavy downpours over coastal areas already dealing with swollen tides.

Weather officials stressed that hazardous conditions will hit the coast whether or not the system forms into a named tropical storm. Dangerous surf, beach erosion, and tidal flooding are expected to lock in along Florida’s eastern coast before spreading north into Georgia and South Carolina.

Looking further ahead, forecasters continue tracking a separate low risk for tropical rain and wind impacts across parts of the Caribbean, Bermuda, and sections of the southeastern United States through Nov. 8.
