Winds in the destructive storm that hit Ottawa and the region on Saturday reached 190 kilometres per hour in some areas, researchers say, but a tornado did not touch down.
"Analysis of the data reveals that a particularly intense downburst, not a tornado, was responsible for the damage" in south Ottawa, the Northern Tornadoes Project at Western University said on Twitter Wednesday morning.
Maximum wind speeds reached 190 kilometres per hour, the researchers said. They measured the storm, known as a 'derecho,' as as EF-2. The EF-scale measures the intensity of wind damage on a scale from 0 to 5.
Local officials are scheduled to provide an update on recovery efforts at 4 p.m. Wednesday. You can watch it live on this page.

Muglia said additional hydro crews are arriving from Toronto on Wednesday to help.
