Storm track and topography

The survey of the NWS Office in Burlington Vermont has prepared a map showing the damage path associated with the July 18 storm. Lighter shading indicates damage consistent with winds in excess of 50 to 60 mph, whereas darker shading indicates damage consitent with winds between 70 and 90 mph with possible gusts up to 100 mph. The yellow "T" mark the position of possible EF0 and EF1 tornado damage along North Cambridge Road and Highway 108, respectively. The damage path runs 6-7 miles long. The worst damage occured in the hollows and valleys running perpendicular to the storms path. This implies strongly that topography had a significant impact on the dynamics of the storm.
