Description
Long track violent tornado. Swath of damage found on Highway 144 NW of Sudbury prompted an aerial investigation of the area. Upon flight over the region, a well defined and obvious convergent pattern of rotary damage was seen from Arden Township to Rhodes Township, a distance of almost exactly 60km, all of which is rugged bush peppered with lakes and rivers. It was noted that a number of camps/cabins had disappeared altogether - this kind of damage is synonymous with an F4 rating (structures with weak foundations blown away some distance). One camp was reduced to a pile of rubble. Another cabin had its roof removed. It was also mentioned that the damage from this tornado was likely higher than that of the Sudbury tornado of 1970 which was rated an F3. Some points along the damage path measured approximately 1800 yards (1.6km) in width, indicating a probable maxi-wedge type storm.
