How wide are tornado damage paths?
Considering all tornadoes, the average path width is near 250 m. That increases to near 400 m for strong to violent tornadoes (EF/F2 to EF/F5) (data drawn from analysis of the ECCC 30-year database).
The widest tornado in the NTP database has a maximum width of 2,440 m! That was the Brooks Lake tornado in northwestern Ontario in 2020.
