Florida Coast Braces for Major Flooding and Erosion From King Tides and Atlantic Storm

Oct 28, 2026

King tides reaching some of the highest levels of the year combined with a slow-moving Atlantic storm could flood coastal communities, erode beaches and disrupt businesses from Florida to South Carolina through the final week of October.

“Persistent onshore winds and rough surf can worsen tidal flooding and beach erosion along the Southeast Atlantic coast, with dangerous rip currents creating hazardous conditions for even the strongest swimmers,” said AccuWeather Lead Hurricane Expert Alex DaSilva.

Miami, Florida, and Charleston, South Carolina, are particularly vulnerable to multiple rounds of coastal flooding as unusually high astronomical tides associated with the full moon combine with persistent winds pushing ocean water toward the shoreline.

Coastal Impacts Along the Southeast Atlantic Coast This Week

Coastal flooding: King tides and persistent onshore winds could inundate low-lying roads, waterfront properties, and flood-prone neighborhoods
Beach erosion and dangerous surf: Rough seas and persistent wave action could accelerate shoreline erosion, while strong rip currents pose life-threatening risks to swimmers
Business and transportation disruptions: Coastal flooding, beach erosion, and hazardous surf could affect tourism, marine operations, cruise itineraries, transportation, and waterfront businesses

Major impacts are expected along parts of Florida’s Atlantic coast, particularly from the central coast northward toward Jacksonville Beach.

Atlantic Tropical Developments Being Monitored

AccuWeather hurricane experts continue tracking a low risk of tropical development off Florida’s coast from October 28-30.

Rapid intensification is not expected, but the area will need to be monitored for gradual development. If the system becomes more organized or develops, heavy rain and gusty winds could affect portions of Florida and the Bahamas.

Regardless of whether tropical development occurs, coastal flooding, dangerous surf, and beach erosion are expected to persist along Florida’s Atlantic coast this week, with hazardous conditions extending northward into Georgia and South Carolina.
