A storm system that rolled through Ontario two weeks ago actually spawned more tornadoes than originally thought.
Tornado researchers with Western University's Northern Tornadoes Project have identified an additional two twisters that touched down during the June 10 storm. Their findings mean there were a total of four tornadoes in the southwestern/midwestern Ontario region within a couple of hours.
The two additional tornadoes touched down in the Huron County communities of Belgrave and Brussels.
After examining the damage left behind, researchers concluded an EF-0 touched down in Belgrave around 5:45 p.m. It travelled a distance of 5.5 kilometres and had a maximum width of 300 metres. At 6 p.m., another EF-0 appeared in Brussels and left a path of destruction 3.1 kilometres long and 150 metres wide.
The pair of twisters downed trees and damaged farm hutches, researchers said.
They touched down roughly two hours before two previously confirmed tornadoes were spotted in Glencoe and Belmont. Those have been determined to have been an EF0 and an EF1.
The ratings put all four tornadoes on the lower end of the Enhanced Fujita scale, which rates the intensity of tornadoes from 0 to 5 based on wind speed and damage caused.
Fortunately, no one was hurt in any of the tornadoes that appeared as a line of severe thunderstorms moved across the region, bringing intense lightning, hail, torrential downpours, and wind gusts up to 120 km/h.
