As Tropical Storm Isaias blasted New York City on Tuesday and left millions without power, the storm's fierce winds sent barriers meant to protect from flooding crashing into city streets.

The National Weather Service (NWS) said a 70 mph wind gust was reported at New York's John K. Kennedy International Airport as the fast-moving storm claimed at least one life in New York.

"One of the most damaging storms the Northeast has ever experienced," Fox News Senior Meteorologist Janice Dean said on "Fox & Friends First."

New York City's power utility said Tuesday night it saw more outages from Isaias than from any storm except Superstorm Sandy in 2012.

In Lower Manhattan, barriers meant to block floodwaters were turned into projectiles as the storm's high winds battered the nation's largest city.

Isaias picked them up and tossed them about as the storm moved past, producing strong winds that at times caused damage.

One person was injured while trying to secure the barriers that ended up strewn on sidewalks and nearby cars, according to a photographer from the Associated Press who was at the scene.

The Aquafence barriers were the same as the ones placed along the waterfront in Brooklyn to protect from storm surge flooding.

Other temporary inflatable flood barriers were installed in New York City to protect against the storm as it approached. They stayed on the ground as opposed to the other ones that got blown over.

One of the large barriers crashed into the back of a car near the subway stop, shattering the vehicle’s rear window, the New York Post reported.

While the barriers that were blown away did not cause major damage, people still headed out into the streets to try to secure them.

Elsewhere in the city a massive tree fell and crushed a van in the Briarwood section of Queens, killing Mario Siles, a 60-year-old construction contractor who was inside the vehicle, police said. He was among the six people killed in the storm.

The fierce wind and rain from the storm forced the Staten Island ferry and outdoor subway lines to shut down.
