Two storms, one coastline on alert

The Atlantic is alive this week. Out in deep water, Hurricane Humberto is roaring with sustained winds near 150 mph, a powerful Category 4 storm. Closer to land, Tropical Storm Imelda is sweeping over the Bahamas, carrying bands of heavy rain and winds of 40 mph.

Forecasters say Humberto will stay offshore, passing west of Bermuda while holding major hurricane strength. Imelda is expected to strengthen into a hurricane early in the week before curving east into the Atlantic. But even without landfall, both storms are already leaving their mark.

Warnings in the Bahamas and Florida

Imelda’s path has triggered tropical storm warnings across the central and northwestern Bahamas — from Cat Island and Exuma to the Abacos and Grand Bahama. Up to 12 inches of rain could drench the islands through Tuesday, raising fears of flash flooding.

In the United States, a tropical storm watch stretches along Florida’s east coast from Palm Beach to Flagler Beach. In Cape Canaveral, FL, residents are watching closely as the storm skirts offshore.

Emergency steps in the Carolinas

Farther north, officials are not taking chances. In Columbia, SC, Governor Henry McMaster declared a state of emergency, sending out swift-water rescue teams and activating 150 National Guard troops. “The time to prepare is now," McMaster warned as the state braced for rain and coastal flooding.

Waves build, beaches on edge

The ocean is restless. Swells from Humberto and Imelda are rolling toward shore, breaking into powerful waves that pound beaches and carve dangerous rip currents.

The first impacts are being felt in Florida and the Carolinas. By midweek, the threat will spread north into New Jersey, Long Island, and New England. Coastal flooding at high tide is expected in many areas, even where skies remain clear.

Rain and surge risks

Imelda is forecast to spread 2 to 4 inches of rain across the Carolinas and southeastern Virginia, with higher amounts possible. Along the coast from Central Florida to South Carolina, a storm surge of 1 to 2 feet could push seawater into yards and roadways during high tide.

Humberto’s size is making matters worse. Its swells are already battering Puerto Rico, the Virgin Islands, and Bermuda, feeding into the same surf that threatens the East Coast.

A long week ahead

From Miami, FL, to Cape Cod, MA, the coastline is bracing for days of pounding waves and dangerous currents. The worst marine conditions are expected Tuesday through Thursday, but forecasters warn the ocean will stay unsettled long after the storms move away.
