Hurricane Erin, once a Category 5 storm, has weakened to Category 3 but remains dangerous as it moves through the Atlantic. Despite its weakening, the storm still carries sustained winds of 125 mph and has prompted emergency declarations in coastal areas of North Carolina. The National Hurricane Center (NHC) warns that Erin will grow in size and remain a major hurricane through midweek.

Erin’s wide wind field means its impact stretches far beyond its center. Hurricane-force winds extend up to 50 miles and tropical-storm-force winds over 200 miles. Puerto Rico, the Turks and Caicos, and the Bahamas are already seeing heavy rainfall, with flash flooding and mudslides possible. Dangerous surf and rip currents are affecting much of the Caribbean and will soon reach the East Coast, Bermuda, and Atlantic Canada.

Although not expected to make U.S. landfall, Erin could still cause serious coastal impacts. Areas from Florida to Massachusetts could face beach erosion, flooding, and dangerous surf. AccuWeather’s Alex DaSilva warned that if Erin shifts farther west before turning north, the U.S. Atlantic coast may see worsening conditions. The Outer Banks, Long Island, and Cape Cod are among areas with the highest risk.

Dare and Hyde Counties in North Carolina have declared states of emergency. Mandatory evacuations are underway for Hatteras and Ocracoke Islands due to expected overwash and flooding from waves up to 20 feet high. Officials stress that even without a direct hit, Erin’s size will bring life-threatening impacts to coastal communities.

Tropical Storm Chantal, which made landfall earlier in July, brought heavy rain, gusty winds, and flash flooding to parts of the Carolinas. Tornado watches were also issued, highlighting how rapidly storm conditions can worsen in the region.

Federal and local emergency officials emphasize preparedness. Residents are urged to know local risks, follow evacuation orders, and keep a go-bag ready with essential supplies and documents in case of sudden displacement.
