The tornado touched down south of List Road and tracked to the 
northeast across Main St. before lifting just south of Pleasant

damage along ~0.6 mile path consisted of about 1-2 dozen 
snapped/uprooted trees (mainly softwood pines) with some tops 
sheared off. Some of the tree tops were lofted 25-45 yards. The
swath of tree damage was about 125 yards wide. Two homes along 
the path sustained minimal structural damage to siding. A wooden 
swing set was also damaged. Based on observed damage indicators, 
the survey team rated the tornado at the high-end of the EF-0 
scale with estimated peak winds around 85 mph.
