Tropical Storm Ophelia makes landfall in North Carolina and will now trek up the East Coast

Tropical Storm Ophelia is heading up the East Coast after making landfall early Saturday near Emerald Isle, North Carolina, delivering heavy rain, strong winds and coastal flooding well beyond its center.

Here are the storm's latest impacts:

The tropical storm roared ashore around 6:15 a.m. with 70 mph sustained winds, just shy of hurricane strength.

By 5 p.m., maximum sustained winds decreased to 40 mph, though the tropical-storm force winds extend up to 310 miles from Ophelia's core, the National Hurricane Center said. It is expected to continue weakening.

TRACK THE STORM

Ophelia's center is on track to move across southeastern Virginia through Saturday night before heading farther north across the Delmarva Peninsula by Sunday, the hurricane center said.

The storm's shield of rain extends hundreds of miles from its center and has dumped heavy rain across a large swath of the mid-Atlantic, including Virginia, Maryland, Delaware, New Jersey and New York.

As Ophelia made its way up the East Coast Saturday evening, the National Weather Service issued a coastal flood warning for communities in New Jersey's Atlantic City, where several roads were closed due to flooding.

"With high tide right around now along the Atlantic coast, we are getting numerous reports from coastal communities of street flooding and road closures," the NWS office in Mount Holly posted on X, formerly Twitter.

Coastal areas in North Carolina bore the brunt of impacts as the expansive storm's center barged into the state earlier Saturday.

Storm surge flooded coastal areas and inlets in North Carolina overnight and winds gusting to 73 mph hit Cape Lookout, along the state's Outer Banks.

The high winds and rain caused treacherous conditions off the coast of Cape Lookout, prompting the rescue of five people, including three children, from Lookout Bight Friday, officials said.

The group had been aboard an anchored sailing vessel "that was beset by weather conditions" with 35 to 40 mph winds, according to a news release from the US Coast Guard.

"The conditions at the time were 6-foot to 8-foot seas, with occasional 10-foot swells," the Coast Guard release said. "The owner of the vessel did not feel comfortable in the channel and requested to be rescued," the Coast Guard said. No one was injured.

Residents of Washington, North Carolina, were warned to "avoid the downtown area" on Saturday as about 3 to 4 feet of storm surge from Ophelia sent waters over the city's boardwalk area, a city Facebook post read.

About 40 miles south in New Bern, which sits along two rivers in North Carolina about 120 miles east of Raleigh, roads were flooded and water crept inland as the levels rose in the downtown area, city officials said on Facebook. Photos posted on the city's page show a flooded children's park and ducks floating down the street on floodwaters.

Emergency crews in New Bern barricaded flooded areas of the city, including Union Point Park, which "looks like a lake," city officials said Saturday morning.

The flooding began on Friday, when roads were submerged in communities along North Carolina's coast. In coastal Cedar Island, water collected on Highway 12, though it was open and passable, the state transportation department said.

"But please don't go out tonight unless you absolutely have to. There is sand and water on the roadway, and it's dark and stormy," the department said in a social media post.

Water levels also rose overnight in the Chesapeake Bay, along the coasts of Virginia and Maryland.

"If you can avoid driving or being out during the storm please do so. We are expecting an extended period of strong winds, heavy rainfall, and elevated tides," Maryland Gov. Wes Moore said.

Ophelia will deliver several key threats through the weekend:

Heavy Rainfall: Some places in eastern North Carolina and southeast Virginia could see between 3 and 5 inches of rain, with locally higher amounts. Other states in the mid-Atlantic could pick up 2 to 4 inches of rain Saturday night through Sunday. Meanwhile, 1 to 3 inches of rain are forecast across southern New York through southern New England beginning Saturday into Monday.

Coastal Threats: Up to 4 feet of storm surge is possible in some coastal areas, particularly in the Hatteras Inlet along North Carolina's Outer Banks and the rivers along Chesapeake Bay.

Storm surge flooding could peak late Saturday with another high tide, particularly in the lower Chesapeake Bay.

The storm will also bring dangerous surf and rip currents along the East Coast through the weekend, the hurricane center warned.

Strong and Gusty winds: Tropical storm conditions will continue to affect parts of the coast of North Carolina and southeastern Virginia through Saturday night.

Severe weather: A few tornadoes are also possible in parts of the coastal mid-Atlantic and North Carolina.
