A conveyor belt of thunderstorms accompanied by gusty winds rolled through the New York region on Tuesday afternoon, snarling train service, knocking out the power for tens of thousands of residents and killing at least two people who were struck by falling trees.

Meteorologists said a line of thunderstorms between 4 p.m. and 6 p.m. produced widespread wind damage from upstate New York through the metro area, and across Long Island and Connecticut.

The storms were accompanied by wind gusts of 50 to 60 miles per hour, which downed trees and power lines and left scores of people without electricity. In Connecticut alone, more than 100,000 customers were without power, according to Eversource. New York State Electric & Gas reported more than 70,000 customers without electricity as of about 9 p.m.

In Dutchess County, about 80 miles north of Manhattan, officials issued an emergency order restricting travel in some areas. Slightly south of there in Newburgh, the police say a tree fell onto a vehicle, trapping an 11-year-old girl who was later pronounced dead at a hospital. And on Twitter, Mayor Mark Boughton of Danbury, Conn., confirmed reports that a man had died after a tree fell on his truck.
