Late October tornado confirmed in southern Ontario

Monday, October 26th 2020, 1:16 pm - The Northern Tornadoes Project has confirmed that an EF0 tornado hit the town of Thornbury amid Friday's severe weather outbreak.

After seeing temperatures soar into summer-like values, a potent cold front helped to trigger late season thunderstorms across parts of southern Ontario on Friday.

The 20+ degree daytime highs were soon replaced with ominous skies, heavy rain and powerful winds. On Monday, the Northern Tornadoes Project confirmed that a tornado had struck the town of Thornbury during Friday's storms.

According to the survey team, the tornado followed a path through the town before entering Georgian Bay.


The tornado has been given a preliminary rating of EF0, with maximum wind speeds up to 130 km/h. The length of its path spanned about three kilometres.

"The tornado produced tree damage and damage to a power pole and street lamp," officials say.

Friday's severe thunderstorms also impacted several areas near and east of Georgian Bay with numerous reports of golfball-sized hail and damaging winds.

With this latest confirmation, Environment Canada and Northern Tornadoes Project has so far verified 40 tornadoes in Ontario in 2020.
