Tropical Storm Elsa is dumping heavy rain as it moves swiftly across New York and the Northeast, grounding flights, delaying trains and threatening floods as it advances along the coast. With top winds of 50 miles per hour, Elsa was about 90 miles southwest of Montauk Point on Long Island and already bringing showers to Manhattan’s Central Park and across Long Island and southern New England, the National Weather Service said. A tropical storm warning extends from New Jersey to eastern Massachusetts including Boston. Flood warnings are posted from Pennsylvania to Maine. Elsa could bring an isolated tornado with it as it moves north. “A large swath of southern New York, Long Island, Connecticut, Rhode Island, through portions of eastern Massachusetts will get 2 to 4 inches of rain with isolated amounts up to 6,” said Lara Pagano, a senior branch forecaster with the U.S. Weather Prediction Center.
