New Hampshire Braces for Damaging Winds, Possible Tornadoes from Shifting NY Storm Line — SevereWX

A potent line of low-topped thunderstorms, already producing wind damage across parts of New York, is shifting northeastward into New Hampshire this afternoon.

The Storm Prediction Center's Mesoscale Discussion 1183 notes strong low- to mid-level winds of 50-60 knots supporting damaging gusts up to 70 mph and isolated tornadoes (likely EF1 intensity, 85-110 mph). This activity trails Watch 352 and could necessitate a new watch soon, with 80% issuance probability within the next couple hours.

Areas at risk include portions of New York, Vermont, New Hampshire, and nearby zones through around 3 PM EDT. VAD wind profiles from nearby radars confirm the robust flow fueling the line's severe potential.

Peak threats:

Stay weather-aware if you're in northern New England—monitor local NWS updates and radar. Have a severe weather plan ready: identify shelter, charge devices, and heed warnings.

Valid: 1:25 PM - 3:30 PM EDT, June 18, 2026
