An 11-year-old boy in Putnam Valley, N.Y., died after a large tree fell and crashed into a home, trapping the boy, the Putnam County Sheriff’s Department said.

A similar thing happened to a child in Chesterfield County, Va. The fire chief there said the child was in bed when a tree limb struck his home, fatally injuring him.

The adults who died in the storm were also killed by falling trees. In Massachusetts, it took more than four hours to extricate a man who was killed when a large tree fell on his car on Friday during the height of the storm, Warren Borsari, the fire chief in Plympton, Mass., said in a phone interview.

In Upper Merion Township, Pa., a 40-foot portion of a tree fell, crushing a car and killing a man inside it, the police chief there said.

The storm’s effects were felt as far south as Georgia and as far north as Maine. In Rhode Island, the winds were so severe that officials shut down the Newport Bridge. In New York City, most flights were grounded for a time on Friday afternoon. In the Washington suburbs, downed trees were strewn across the streets.
