Rare November tornadoes strike Long Island and Connecticut.

A record number of tornado warnings have been issued since Oct. 1, with offshore waters near record highs.

Multiple tornadoes struck several Northeast states on Saturday in an unprecedented November outbreak, snapping trees and leaving behind pockets of structural damage to homes and businesses.

The mini-swarm of tornadoes occurred as an intense, tightly wound impulse swept across the region, drawing energy from near record-warm Atlantic Ocean waters. A strong cold front accompanying the disturbance incited a line of powerful thunderstorms, some of which began to rotate as they slid through Long Island and into southern New England.

Radar imagery showed numerous instances of debris lofted amid this rotation, prompting the National Weather Service to issue a total of 12 tornado warnings across New York, Connecticut, Rhode Island and Massachusetts.

At one point, two simultaneous tornadoes were probably ongoing near Islip in Long Island. The Weather Service office in New York City is conducting damage surveys near Mastic and Shirley on Sunday to determine whether and where tornadoes touched down and to assign damage ratings. In Shirley, a shopping center suffered heavy damage from the storms.

In Connecticut, three probable tornadoes struck Cheshire, Branford and Plainfield, with radar imagery showing rotation and debris. In Cheshire, a trampoline was blown into power lines, while snapped trees damaged some property and cut electricity to thousands. The Weather Service is also surveying the damage in this area on Sunday. . .

Tornado warnings were also issued in Providence, R.I., and in Cape Cod and Martha’s Vineyard in Massachusetts.'
