| Brief Description: A warm front, moving into Connecticut, produced a line of showers and isolated thunderstorms during the early afternoon of June 23. One cell developed into a supercell which then spawned two tornados in Litchfield County. The first tornado touched down in the northern end of the town of Washington, on a golf course near Lake Waramaug, cutting a path 50 yards wide and a mile in length. It hit during a lull of a golf tornament that was going on there, damaging the fourth hole of the course as well as destroying a metal fence around a tennis court. This tornado also demolished a storage building. This was ranked as an F1 Tornado, with winds estimated between 75 and 100 mph, by National Weather Service Personnel. The tornado also took out many trees around this area. The tornado lifted back up, but then reformed from the cell as the storm moved into the cities of Torrington and Winstead. This second tornado was ranked on the Fujita scale as an F2 with winds estimated between 100 and 130 mph. It touched down near the Torrington Middle School, over the Midget Football Field cutting a swath two hundred yards wide and a half a mile in length. The tornado destroyed an 8,000 dollar shed that had recently been completed by the Midget Football League. The second twister also demolished the bleachers and part of a roof at the Torrington Middle school. In addition, hundreds of large trees were uprooted. Powerlines were also destroyed. One person was injured when a portion of the blown off roof fell on him, resulting in bone fractures. | |||||||||||

| Brief Description: On July 3, a fast moving cold front crossed Berkshire County during the afternoon and evening hours. The front initiated four tornadoes. The Richmond F1 tornado is a continuation of the F2 tornado which occurred in Columbia County. This tornado downed trees and produced minor damage to one house as it diminished in the Richmond area. The tornado in the Town of Florida began at the intersection of South County Road and Savoy Road. The F1 tornado tracked eastward and terminated just south of Florida near state route 2. The tornado removed all the shingles off the roof of a residence and a prefabricated steeple was blown off a church. Many trees were also downed along its path. The F2 tornado which began in the Monterey area started at the intersection of Wellman Road and New Marlborough Road. The tornado tracked northeast across state route 23 and Lake Garfield to Hayes Pond where it merged with the second tornado. At the north end of Hayes Pond the tornado diminished. This tornado downed hundreds of trees, damaged ten to twenty homes and destroyed two vehicles. The damage was most extensive along the north shore of Lake Garfield at Elephant Rock Road, Hopi Road, Mt. Hunger Road and Norwalk Acres Road. The second F2 tornado began near the intersection of Tyringham Road and West Center Road. It then tracked across Hayes Pond where it momentarily merged with the other tornado. The tornado then proceeded northeast where it ended near the intersection of state route 8 and Merrit Road. This tornado produced extensive tree damage, destroyed one vehicle and damaged fifteen to twenty homes. The most extensive damage occurred along West Center Road near Hayes Pond. Baseball size hail was also observed at Hayes Pond with this storm. Two people were struck by lightning at the Great Barrington Fairgrouds. They were both hospitalized and released. | |||||||||||

| Brief Description: A cluster of severe thunderstorms formed north of an approaching strong warm front and moved east-southeast, just north of the front. A severe thunderstorm produced a tornado along the south shore of the North Fork of Suffolk County on Long Island. The tornado touched down and lifted several times along a 4 mile path as it moved east-southeast from just southeast of Mattituck Air Base, across Marratooka Pt., Kimogener Pt. (of New Suffolk), Cutchogue Harbor, Central Nassau Pt., then lifted as it crossed Hog Neck Bay. The National Weather Service Survey showed that the tornado touched down first in southern sections of Mattituck. This was in the backyard area bounded to the west by Marratooka Road, to the north by Center Street, and to the south by Park Ave. Most damage at this location was to trees, where many tops were twisted off and several snapped off at 5 to 15 feet above the ground. This was estimated as F1 damage. The tornado "bounced" and continued east to the dirt road extension of Park Ave., where it lifted the roof off a cottage at #520. The roof of the building detached from the house and was carried about 115 feet to the northeast. The tornado continued east for about 1/2 mile, then touched down again at 10 Kimogenor Point. It ripped off the porch and part of the main roof of the house. It apparently developed a few separate vortices at this location. One twisted a 100 year old metal windmill over high tension power lines and did some significant damage to large trees. Another vortex slammed into the front porch at 2 Kimogenor Point. It ripped off the porch and a large section of the roof of the house. The lone inhabitant said he saw a "wall of water" heading toward his house and instinctively dove into the stone fireplace to protect himself as the storm hit. Winds were estimated over 100 mph over this part of the tornado's path. The tornado continued east along Jackson Ave. causing havoc with many mature trees in the area. The most significant damage occurred in the vicinity of Jackson Ave. and Fifth Street, where winds were estimated from 110 to 120 mph, due to the devastation to many large trees. This was the area where F2 damage was observed. This was also the widest path width, which was estimated at 300 yards. The tornado continued east along Jackson Ave. creating F1 damage then went over Cutchogue Harbor. Eyewitnesses from Nassau Point (Little Hog Neck) said they saw the tornado over the water just east of New Suffolk. They saw several suction vortices rotating around the main funnel. The tornado moved across Nassau Point, in the vicinity of Wunnaweta Pond, where it twisted and sheared off many trees that fell on and damaged houses. It bounced again and hit close to the ground near #6225 and #6325 Nassau Point Road. Many trees fell onto and damaged homes. These backyards were on top of a cliff overlooking Hogs Neck Bay. The tornado lifted before hitting these homes. This was the last indication of tornadic damage. The latest cost estimates of damage from the Southhold Supervisor's Office are in excess of $1 million dollars. One injury occurred as a person was struck by flying debris. | |||||||||||
