People who live along Lake Street in Haddonfield say the storm came through very quickly.
Video from Chopper 6 showed a massive tree across the street, with a mass of branches sprawled over a roof.
Another tree came down onto a row of cars behind the Kingsway apartments.
"I came out to put my laptop in the car - I didn't hear anything - I came out and the tree was on everyone's car," said Ashley Shepley of Haddonfield.
"I heard a couple drops, the wind just kept swirling worse than normal and then all of these trees were going like crazy, and I was just watching out here in awe. And then the door slammed shut, I heard a couple pops, and then this just came down across all these cars," Mike Maryott of Cherry Hill.
A downed tree along Haddon Avenue near Locust brought a pole down with it near a gas station, closing the road.
People surveying the damage are thankful it wasn't worse.
According to Haddonfield's mayor, PSE&G reported hundreds of customers without power on Wednesday evening.
Officials are asking people to watch for downed wires as crews try to clear trees.
