More twisters confirmed to have hit western Quebec on Friday
Environment Canada has confirmed that three additional tornadoes touched down in western Quebec on Friday - bringing the day's total number of twisters in the Ottawa-Gatineau area to six.
At around 3:30 p.m. ET, a tornado touched down about 30 kilometres from Mont-Laurier, Que., near the Baskatong reservoir, the weather agency said Tuesday.
It likely travelled about 10 kilometres through the wooded area, snapping trees and downing power poles as it went, Environment Canada said.
About 90 minutes later, another touched down near the Val-des-Bois, Que, area, about 90 kilometres north of Ottawa.
That twister travelled east-northeast for about 13 kilometres, damaging buildings and snapping trees before dissipating near the town.
Satellite images also allowed the agency to confirm a third tornado touched down roughly 25 kilometres north of Otter Lake that day and cut a three-kilometre swath through the forested area.
All three twisters were likely EF-1 tornadoes, Environment Canada said, meaning they had wind speeds between 135 and 175 km/h.

According to David Sills, a severe weather scientist with Environment Canada, the Ottawa-area tornado is only the second EF-3 or higher recorded in Canada in September or later. The other occurred in 1898 in the Niagara region. The 2011 Goderich EF-3 tornado was the last recorded in Ontario.
