At least five people were killed when Tropical Storm Isaias spawned tornadoes, downed trees and dumped flooding rains as it roared up the East Coast on Tuesday.

A Pennsylvania woman died when she attempted to drive her car into high water and was swept into a creek, local newspaper The Morning Call reported.

As of 8 p.m. EDT, the U.S. National Hurricane Center reported maximum sustained winds of 50 mph, though they reached as high as 65 mph earlier Tuesday. It was moving north-northeast across Vermont at 40 mph.

"Strong and damaging winds will continue to spread northward across the New York City metropolitan area, including eastern Long Island and southern New England, that could knock down trees and power lines," the hurricane center said.

More than 12 hours after coming ashore in North Carolina, the storm was causing destruction hundreds of miles north into the New York City metro area.

Two people died and about 20 were injured after one of the tornadoes spawned by the storm “totally demolished” several mobile homes in Windsor, North Carolina, according to Juan Vaughan II, county manager for Bertie County.

Three people were unaccounted for, authorities said.

"We’re still in active searches going on right now,” Vaughan said. “We really want to make sure everyone is found safe as soon as possible.”

An aerial shot by WRAL-TV showed fields of debris where rescue workers in brightly colored shirts picked through splintered boards and other wreckage. Nearby, a vehicle was flipped onto its roof, its tires pointed up in the air.

“It doesn’t look real. It looks like something on TV. Nothing is there,” Bertie County Sheriff John Holley told reporters. “All my officers are down there at this time. Pretty much the entire trailer park is gone.”

The National Weather Service confirmed tornadoes in Virginia, Maryland, Delaware, Pennsylvania and New Jersey.

Another possible tornado was reported in the Philadelphia area, where the parking lot of the Doylestown Hospital was littered with cars.

Nearby a large chunk of the roof of a daycare center was torn off by the wind gusts, FOX29 reported. The building was reportedly evacuated and no injuries were sustained.

Forecasters expected the storm to hold its strength and spin-off damaging winds on a path into New England on Tuesday night.

According to power-outage tracking website poweroutage.us, more than 2.2 million electric customers were without power along the East Coast, including 1.3 million in New Jersey.

Most of the significant damage seemed to be east and north of where the hurricane's eye struck land.

Forecasters had clear warnings earlier, as Isaias approached land, for a life-threatening storm surge along the coasts of North and South Carolina.

Nevertheless, some veterans of earlier storms thought their areas would be spared.

Royce Potter, a fifth-generation seafood purveyor and owner of Potter’s Seafood in Southport, told the Associated Press he rode out the storm on a boat docked near his business, which was damaged by the wind and water.
