HAMPTON FALLS, N.H. (AP) – Heartened by an outpouring of community support, the owners of a family campground on Saturday began cleaning up after a powerful storm downed trees, trapped campers and injured 10 people.

“There’s a ways to go, but we’re doing a great job,” said Karen Bark, co-owner of the Wakeda Campground. “Whole families have shown up with their work gloves on, and husbands with chain-saws, so we’ve had a very productive day.”

Police said a narrow, localized thunderstorm cell caused extensive damage at the park Friday night. “It was pretty fierce here,” Fire Chief Jay Lord said.

He said it took about an hour to free one camper after a tree landed on his trailer.

Of the 10 people injured, eight were in stable condition Saturday afternoon, Bark said. The other two suffered more serious injuries; one was in critical condition, the other in guarded condition, she said.

“People were just screaming,” said Rebecca Duclos of Manchester, who was staying with her husband and two children at the camp.

Power lines and trees were downed at the campground and along the roads leading to it.

Josh Grant, of Newbury, Vt., said his parents were hospitalized after a tree crushed their camper. He said both were conscious when reached by rescuers, but were pinned and impaled by branches.

The camp, located not far from the seacoast, has 400 camp sites and cabins over 180 acres. Bark said about 300 of them were occupied, with about 900 present for the storm. Campers were asked to leave on Saturday, and the Red Cross opened a shelter at the Lincoln-Ackerman School for people whose campsites were seriously damaged.

“When the weather clears, they can come back in but we probably won’t have power for another day or so,” Bark said. “We’re not closed, but we’re not encouraging new business.”

Even some of the cleanup workers were told to take a break when the weather took another turn for the worse.

“We had a pretty good thunderstorm a little while ago so we asked people to go to the movies and not come back until they see stars shining through,” Bark said.

Elsewhere in the Northeast, thunderstorms in Connecticut knocked out electrical service to more than 32,000 homes and businesses, Connecticut Light and Power said. That included 74 of the customers in the town of Glastonbury, the utility said. Nearly 5,000 customers still had no power Saturday morning.

Storms also caused scattered power outages in Massachusetts; a tornado in Pittsfield damaged buildings and ripped the roofs off the dugouts and clubhouse at a park.
