|Brief Description: A small, but rather intense, tornado touched down on Interstate 95 about two miles south of the Hampton Toll Booths in the town of Hampton Falls. While several funnel clouds were observed over southeastern New Hampshire that Sunday evening, the actual tornado touched down just as one of the funnel clouds approached I-95. The tornado then lifted off the ground about 100 yards after crossing I-95. The most significant damage was to a truck parked along the side of the highway. The trucked was lifted off the ground briefly by the tornado, thrown about 10 feet, landed on the passenger side, and then rolled 1 1/4 times ending up on its roof. Two men were in the truck at the time and were taken to a nearby hospital for treatment. After interviews with the occupants and eyewitness reports which indicated that the vehicle was lifted into the air, the tornado intensity was classified as F2 on the Fujita scale. These reports were consistent with the ground-based assessment.|

|Brief Description: Very severe thunderstorms moved through Cheshire and Hillsborough Counties, producing two tornadoes, microbursts, damaging thunderstorm winds, and large hail. It appears that a microburst hit Hinsdale and both a microburst and weak tornado affected the town of Swanzey, just south of Keene, in Cheshire County. A horse barn was destroyed and an ice arena damaged at the Cheshire Fairgrounds. Pieces of aluminum were wrapped around street lamps and two-by-fours were driven into the metal sides and roof of the ice arena. One person was slightly injured by flying glass fragments when her car windows were blown in. Many trees were uprooted or blown down. Damage was estimated at approximately $500,000 at the Fairgrounds. There was evidence of both straight-line wind damage and some rotation associated with this storm. In Hillsborough County, a tornado touched down in the western portion of the town of Greenfield just to the west of Otter Lake. It then moved to the northeast, damaging a sawmill, destroying a recycling facility, and damaging some buildings at a campground. Wood and aluminum buildings were torn apart or blown over. Many large trees were broken off near their bases and hundreds more had their tops broken off. There were no injuries reported. Trees were reported blown down in Marlborough and a microburst may have occurred in nearby Dublin, where numerous trees and tree limbs were blown down along the shore of the Howe Reservoir. All of the aforementioned damage was along a path cut by the same thunderstorm complex. However, trees also were reported blown down in the towns of Walpole and Marlow in northern Cheshire County from a separate cluster of thunderstorms. About 1,700 electric customers in the Monadnock Region lost power during the storms. Most of the outages occurred in the towns of Marlborough, Marlow, Richmond, Swanzey, and Winchester. Another 100 lost power in Walpole. Statewide, about 10,000 electric customers lost power.|

|Brief Description: A short-duration minimal F2 tornado moved along a half-mile long track which averaged 85 yards wide in Antrim in northwest Hillsborough County. A National Weather Service survey team investigated the damaging effects of this tornado and spoke with many eyewitnesses. One resident recalled seeing the NWS' Tornado Warning (which specifically mentioned Antrim) scroll on Cable TV a few minutes before the tornado struck. The tornado began at Nahor Hill and travelled north-northeast about a half mile before ending up just past the Great Brook Elementary School. Along the middle of its path, a wooded stretch sustained severe tree damage. Most of the trees were either uprooted or snapped in half...and they fell in different directions. A small boat was flipped over and a camper-trailer was turned around and flipped over. A single family home had some shingles torn off. An apartment complex resident said he saw the metal garbage dumpster rise a short distance while a dark gray-black cloud went by. At the elementary school, a wall was damaged. Only minor damage and no injuries occurred as a result of this tornado, but had the track been only a few hundred yards to the east, it could have caused significant damage to the center of the small town of Antrim.|
