Hi-res satellite imagery comparison before and after the EF3-rated #tornado that devastated much of #Dunrobin, ON on Sept 21st. This is only a portion of the longer track that includes #Kinburn, ON and #Gatineau, QC. We measured a max path width of over 1km yesterday. #onwx #qcwx pic.twitter.com/ziXWeeYYZ1
