Hurricane Erin updates: Storm weakens to Category 1, moves away from US coastline

High surf advisories continue into the weekend from the Outer Banks of North Carolina up to coastal New England as Hurricane Erin moves northeast.

Additionally, the rip current danger is expected to be high on Friday from Florida all the way up to Maine, with similar conditions expected this weekend. Swimming at any East Coast beach this weekend is not advised.

Erin is expected to weaken as it continues east out to sea, eventually becoming a post-tropical system over the North Atlantic that resembles a nor’easter rather than a tropical system.

As of Friday morning, Hurricane Erin continued to move northeast and is weaker than days prior, with maximum winds down to 90 mph and all tropical storm warnings discontinued.

Erin is still a very large storm impacting the East Coast with coastal flooding, dangerous surf and breezy conditions.

Coastal flood alerts remain in effect from the Carolinas to Long Island and Coastal New England where 1 to 2 feet of inundations is possible in low-lying areas with high tide through Saturday.

While the worst of Erin has already passed and the storm will continue to race away from the U.S. into the weekend, there will still be some lingering impacts -- including beach erosion and coastal damage from large waves and coastal flooding along the shoreline.

Due to the high surf and rip current risk, New York City is extending its swimming ban.

Beaches were at first closed to swimming on Wednesday and Thursday, and now will also be closed for swimming on Friday. Wading is also not allowed, officials said.

Erin, a massive Category 2 hurricane more than 700 miles wide, is located about 285 miles east of North Carolina’s Outer Banks and is moving northeast through the Atlantic.

Tropical storm and storm surge warnings remain in effect for the Outer Banks, where wind gusts could reach 50 mph and the surge could climb to 4 feet.

Coastal flood alerts are in effect from the Carolinas up to coastal Connecticut, where 1 to 3 feet of inundation is possible in low-lying areas.

Large waves and flooding may inundate property and roads along the coastline, especially in the Outer Banks.

Hurricane Erin will weaken as it moves away from the East Coast over the next 24 hours, but coastal impacts -- especially in the Northeast -- will linger through Friday and potentially into Saturday.

High surf advisories continue from Florida to Maine.

The peak of the waves along the Mid-Atlantic and Northeast beaches will be Thursday and Friday. Waves could reach 17 feet from the Outer Banks to New Jersey to New York.

Waves could climb to 20 feet in Rhode Island, Massachusetts and Maine Thursday night through Saturday.

The rip current danger is high from Florida to Maine on Thursday, and the threat will last through Friday.
