Hurricane Erin forecast to churn up dangerous swells and winds from Florida to New England

Warnings about rip currents have been posted from Florida to the New England coast with New York City closing its beaches to swimming on Wednesday and Thursday. Several Long Island and New Jersey beaches also will be off-limits.

"Enjoy the shore, enjoy this beautiful weather but stay out of the water," New Jersey Gov. Phil Murphy said Tuesday.

Off the coast of Massachusetts, Nantucket Island could see waves of more than 10 feet (3 meters) later this week. But the biggest threat is along the barrier islands of North Carolina's Outer Banks where evacuations have been ordered. At least one town asked residents to secure their trash cans so they don't float or blow away.

Erin has become an unusually large and deceptively worrisome storm while moving through the Caribbean, with its tropical storm winds stretching 200 miles (320 kilometers) from its core. Forecasters expect it will grow larger in size as it moves through the Atlantic and curls north.

It continued to lash the Turks and Caicos Islands on Tuesday, where government services were suspended a day earlier and residents were ordered to stay home, along with parts of the Bahamas before it's expected to turn toward Bermuda and the U.S.

By Tuesday, Erin had lost some strength from previous days and dropped to a Category 2 hurricane with maximum sustained winds of 105 mph (170 kph), the National Hurricane Center in Miami said. It was about 655 miles (1,050 kilometers) south-southeast of North Carolina's Cape Hatteras.

Rough ocean conditions already have been seen along the U.S. coast — at least 60 swimmers were rescued from rip currents Monday at Wrightsville Beach, near Wilmington, North Carolina.

The biggest swells along the East Coast are expected to develop Wednesday and last into Thursday.

Two years ago, Hurricane Lee grew with surprising speed while barreling offshore through the Atlantic, unleashing violent storms and rip currents up and down the seaboard.

Climate scientists say Atlantic hurricanes are now much more likely to rapidly intensify into powerful and catastrophic storms fueled by warmer oceans.

On the Outer Banks, local leaders said Erin's storm surge could swamp roads with waves of 15 feet (4.6 meters). Mandatory evacuations were ordered on Hatteras and Ocracoke Islands, and more than 1,800 people had left Ocracoke by ferry since Monday.

North Carolina Gov. Josh Stein warned residents along the coast to be prepared in case they need to evacuate and declared a state of emergency on Tuesday in advance of the storm. Bulldozers were busy shoring up the dunes, and on Hatteras, the owners of a pier removed a few planks, hoping the storm surge will pass through without tearing up the structure.

Holly Andrzejewski, who just bought a bed-and-breakfast on Hatteras Island with her husband, said they spent the last few days bringing in all the outdoor furniture and making sure there were generators, extra water and flashlights.

"It's just one of those things where you know this is always a possibility and it could happen, and you just make the best out of it. Otherwise you wouldn't live at the beach," she said.

The Outer Banks' thin stretch of low-lying barrier islands that jut into the Atlantic Ocean are increasingly vulnerable to storm surges. There are concerns that parts of the main highway could be washed out, leaving some routes impassible for days.

Farther south, no evacuations had been ordered, but some beach access points were closed as forecasts call for water levels up to 3 feet (1 meter) over normal high tides for several days.
