Miami, FL — South Florida's Atlantic coastline faces a potentially dangerous combination of coastal flooding, powerful winds and hazardous seas through Monday, Oct. 26, with major tidal flooding possible and offshore wave heights reaching up to 14 feet.
According to the National Weather Service in Miami, moderate coastal flooding is expected through Sunday, while a Coastal Flood Watch highlights the potential for major flooding Sunday into Monday. Hazardous marine conditions are also expected to intensify across Atlantic waters.
Coastal Flooding Could Worsen Sunday and Monday A Coastal Flood Advisory remains in effect along portions of South Florida's Atlantic coast, including coastal communities in Palm Beach, Broward and Miami Dade counties.
Forecasters expect the highest water levels around morning and evening high tides, generally between 5 and 8 a.m. and 5 and 8 p.m. through the weekend.
Unusually high tides could flood low lying streets, waterfront neighborhoods and other vulnerable coastal areas.
Residents in Miami, Fort Lauderdale and West Palm Beach should remain alert for changing conditions, particularly during peak high tides.
Gale Conditions and 14 Foot Seas Possible Marine conditions are expected to deteriorate further Sunday afternoon.
A Small Craft Advisory covers local waters, extending through Sunday afternoon in the Atlantic and Monday evening in the Gulf.
Northeasterly winds of 20 to 30 knots are forecast, with Atlantic seas potentially reaching 9 to 14 feet during the Gale Watch period from Sunday afternoon through Monday evening.
Wind gusts could reach 35 knots, creating particularly dangerous conditions for smaller vessels.
Boaters are urged to avoid navigating in hazardous conditions.
Coastal residents should also avoid driving through saltwater flooding, which can conceal road hazards and damage vehicles.
Conditions may remain dangerous into early next week as elevated tides and strong marine winds continue.
