EF1 Tornado staring in Bethany, CT and ending in North Haven, CT. Maximum path width of 500 yards and a path length of 11.1 miles.
Based on a National Weather Service damage survey done in
conjunction with CT Division of Emergency Management and Homeland
Security and local CT town emergency managements, it has been
determined that a strong EF1 tornado, with maximum wind speed of
110 mph, tracked southeast from Bethany to North Haven CT.
The tornado first touched down in a forested area to the
southeast of Judd Hill Rd in Bethany CT. The tornado tracked
southeast over primarily forested areas from Amity Rd, to Munson
Rd towards Litchfield Tpke, creating a path of damage about 75
yards wide, with hardwood tree damage consistent with wind speeds
of 80 to 90 mph.
The path of damage widened to around 300 yards as the tornado
tracked southeast towards Lake Bethany. Structural damage,
including significant roof damage to several homes, and snapped
hardwood trees indicated wind speeds of around 100 mph in this
area.
The tornado path continued southeast for another 4 miles to near
the town center of Hamden CT, with tree and structural damage
indicative of wind speeds of 70 to 80 mph. The intensity picked up
significantly as the tornado approached the center of Hamden, as
evidenced by extensive damage to numerous buildings, including the
flat roof of a 2 story building across from Hamden Town Hall
being torn apart. Wind speeds are estimated to be around 100 mph
based on the damage to these buildings, bent metal fencing around
town hall, and uprooted and snapped trees.
The tornado reached maximum strength and width from this point on
as it continued southeast across Wilbur Cross Parkway, Interstate
91, and down to the intersection of Arrowdale and Thompson St in
North Haven, CT. Tremendous hardwood tree damage and structural
damage was indicative of wind speeds of 110 mph and an expanded
width of 500 yards. It is a this point that the tornado appears to
have dissipated with its destructive straight line winds fanning
out to the coast.
