The most extensive damage was not continuous...but occurred in pockets. Trees sustained the majority of the damage. Many tree branches and limbs were blown down...and several trees were also snapped off or uprooted. A few residential structures sustained roofing damage...as did several grain bins and farm outbuildings. The maximum wind speeds in the damage area were estimated from 75 to 85 mph.
