Lightning hit a Boy Scout camp in Gilmanton, N.H., Monday evening, injuring 23 campers, said the fire chief in nearby Belmont, N.H., whose department responded to the site.
Chief David Parenti said that most of the concern centered on six of the campers at Griswold Scout Reservation, 87 miles north of Boston, because of the location of burns on their bodies, but that the injuries were not serious.
The campers and several adults had taken shelter under a tarp during a serious storm, when lightning struck the tarp, Parenti said. Everyone under the tarp was affected by the strike, he said.
The campers were taken to Lakes Region General Hospital, Franklin Hospital, Concord Hospital, Huggins Hospital, and Speare Memorial Hospital. The adults declined to go to a hospital.
The storm was part of a system that swept through Massachusetts, as well, with reports of hail and lightning strikes.
A National Weather Service spokeswoman said that 1-inch hail was reported in Greenfield and Leverett, with ¾-inch hail in Danvers and Topsfield. Gusts of 50 miles per hour were also reported in parts of the state.
Two people sustained minor injuries when lightning hit an umbrella outside the Cask ’n Flagon restaurant in Marshfield, sending the umbrella through a window, said Shaun Robinson of the Marshfield Fire Department.
Lightning strikes started fires at houses in Winthrop and Hingham, said local fire departments. No injuries were reported.
No significant damage was reported in Boston, said Boston Fire Department spokesman Steve MacDonald.Globe correspondent Haven Orecchio-Egresitz contributed to this report. Nicholas
