A rapidly moving column of sinking air called a microburst is likely to blame for the damage caused when a powerful storm moved through the National Capital Region Wednesday afternoon, Environment Canada says.

 

The Britannia Yacht Club on the Ottawa River recorded a wind gust of about 160 km/h at 3:08 p.m. Wednesday, the weather agency said in a French-language notice posted on its website Friday. Staff at the club confirmed the reading to CBC Thursday.

Winds moving that fast are consistent with F1 tornadoes, but microbursts can also cause winds at speeds of more than 100 km/h.
