A storm survey team from the National Weather Service confirmed Friday that a tornado touched down Thursday afternoon in southwestern New Hampshire.
It was the state’s first tornado in 2023.
The tornado first touched down in North Swanzey, then it lifted briefly and touched down again near the border of Keene and Marlboro, before skipping eastward along Route 101 to Dublin, where it toppled several hundred large healthy trees, the team reported Friday evening. The tornado traveled a 13-mile path.
The damage in Dublin included broken windows, siding and shingles ripped off of structures, and trees fallen on cars and buildings, according to the report.

The team reportedly observed damage that was consistent with an EF-1 tornado with maximum winds of 90-95 mph. The weakest tornadoes are classified as EF-0 and the strongest as EF-5, which have wind gusts of 200 mph or greater.
Video published by WMUR shows uprooted trees and a damaged solar array left in the storm’s path.
New Hampshire had two EF-1 tornadoes last year. The first touched down in Charlestown in May 2022, and the second touched down in Chesterfield in July 2022, according to National Oceanic and Atmospheric Administration data and news reports.
An EF-2 tornado that touched down in 2008 left one person dead.
The New Hampshire Department of Safety said severe weather events underline the importance of preparedness.
“Stay informed, have a plan, and make a kit,” said Robert Buxton, director of the department’s Division of Homeland Security and Emergency Management. “If a warning is issued in your area of the state, take action.”
