Ontario tornado upgraded to EF-2, second twister confirmed
Friday, June 15, 2018, 3:43 PM - Environment and Climate Change Canada has upgraded a tornado confirmed after Wednesday's strong storms, and confirmed a second twister as well.
In a statement Friday, the agency says the first tornado, part of a storm that affected Haldimand and Norfolk counties Wednesday afternoon, was actually an EF-2 tornado, with maximum winds of 180 km/h. It had initially estimated the twister at EF-1 strength, with peak winds of 160 km/h.
Environment Canada normally assesses tornado strength based on post-storm damage surveys, and a survey team found significant damage in the tornado's path near the towns of Jarvis and Waterford, which was approximately 32 km long with a maximum width of 500 metres.
"Numerous trees were uprooted or sheared apart, multiple buildings suffered shingle damage, branches were embedded into the roof of a house, a flag pole was snapped, a port collapsed, and several barns were destroyed," Environment Canada says.
A second tornado was confirmed from Wednesday near Norwich, based on video evidence. That twister did "minimal damage," and has been classed as an EF-0.

The storms which produced those tornadoes triggered severe thunderstorm warnings across much of the south of Ontario as they gradually moved east.
