Weather summary for Ontario and the National Capital Region issued by Environment Canada at 3:36 a.m. EDT Thursday 26 May 2022. Discussion. A derecho, which is a widespread long-lived windstorm associated with a line of thunderstorms, developed near Sarnia late Saturday morning and tracked northeastward over Southern Ontario, crossing Ottawa Saturday afternoon. Damaging wind gusts were reported over a large swath of Southern Ontario as the severe thunderstorms raced through. After a preliminary analysis of the extensive damage in Uxbridge, Ontario, Western University's Northern Tornadoes Project Team has officially confirmed an EF2 tornado was embedded within the leading edge of the derecho. The tornado occurred at approximately 1:15 PM EDT on Saturday afternoon in Uxbridge and was found to have a maximum wind speed of 195 kilometres per hour. The Northern Tornadoes Project Team has also confirmed that an intense EF2 downburst occurred in Southern Ottawa on Saturday with maximum wind speeds reaching 190 kilometres per hour. This downburst was responsible for substantial amounts of damage including downed hydro towers. There have been at least ten fatalities reported as a result of the strong winds with this line of thunderstorms. There was also extensive damage to trees, power lines and buildings. There were also overturned cars reported as well as widespread power outages. More than 1,000,000 customers were without power from this storm Saturday. Power outages continue in many areas today. The following is a summary of peak wind gusts observed with this line of thunderstorms in kilometres per hour: Kitchener - Waterloo Airport 132 Ottawa International Airport 120 Toronto Pearson International Airport 120 Toronto Buttonville Airport 110 Brantford Airport 104 Uxbridge 100 Elora 99 Ottawa Central Experimental Farm 93 Gatineau 90 Oshawa Airport 89 Toronto Island Airport 89 Trenton 83 Guelph 83 Western University's Northern Tornadoes Project continues to investigate whether there were additional tornadoes or downbursts embedded in the Derecho.
