Tornadoes are fairly common in Canada. In fact, Canada is second to the United States in th number of tornadoes per year. Tornadoes commonly occur across southern Alberta; Manitoba and Saskatchewan; southern Ontario; southern Quebec; the interior of British Columbia; and western New Brunswick. Tornado season in Canada usually runs from April to September with peak months in June and July, but of course can occur at any time of year.
This year, there was a higher than normal occurrence of the intrusion of warm moist air over central and eastern Canada. Severe weather develops when warm, moist air clash with dry, cool air. Tornadoes develop when there are strong updrafts and rotating winds with height.
