Virginia (CNN) -- The voices in the video tell the story.
"Something crazy is going on outside," a woman shouts. "I'm scared."
Moments later, the same voice yells that a tree has fallen and another says, "It's on that guy's camper."
Overturned campers, downed trees
The footage posted on the website of CNN affiliate WAVY came from the Cherrystone Family Camping Resort on the Chesapeake Bay in Virginia, where a powerful storm Thursday toppled campers and sent trees crashing onto vehicles.
Police said two people died, and a hospital official said 25 others treated for injuries included three in critical condition.
Photos from the scene in Northampton County showed overturned campers, with a downed tree crushing one vehicle.
The area was under a tornado warning, and Danielle Rivera -- who shot the video footage -- told WAVY of giant hail and crushing winds that tore off the awning of her family's camper.
"I was terrified"
"I was terrified," the 17-year-old Rivera said. "I was so scared."
She and her mother decided to stay in the camper until the hail and wind relented enough for them to make a dash to their car.
"I thought a tree was going to fall on us," she said.
State Police spokeswoman Corrine Geller said emergency personnel searched the area for additional casualties, and survivors got bused to a high school set up as a temporary shelter.
Riverside Shore Memorial Hospital was treating 25 people injured by the storm, with three in critical condition, according to spokesman Peter Glagola. Most of the injuries involved broken bones and head trauma, he said.
According to the National Weather Service, a cluster of "supercells" ahead of a cold front formed a storm over Chesapeake Bay just after 8 a.m. ET.
The storm intensified as it moved on ashore about 30 minutes later. The area was under a tornado warning issued at 8:20 a.m.
Cherrystone opened in 1964 occupies 300 acres with 725 sites including cabins, cottages, and deluxe campers, its website says.
Rivera told WAVY she and her family had been going there for 10 years, but "never have I ever witnessed anything this bad."
