Extreme weather in the Northeast left five people dead and half a million without power. An 11-year-old girl was killed Tuesday afternoon when strong winds caused a tree to fall on a parked car in Newburgh, New York, with her mother escaping with minor injuries. Three others were killed by falling trees in Connecticut and another man was killed near the Pocono Mountains in northeastern Pennsylvania. As of 8 p.m. ET, 496,777 customers in Pennsylvania, New York, New Jersey, and Connecticut had lost electricity, ABC News reported. The most extreme storms had dissipated by 10:30 p.m. but flash-flood warnings were still in effect for eastern Maryland, Delaware, and southern New Jersey, said Frank Pereira, a meteorologist with the NWS. Pereira added that hail the size of tennis balls smashed car and house windows in Hartford.
