We just endured a very frightening day here in Ontario (May 21, two weeks ago), with those derecho winds wreaking havoc for a very long stretch, north and east of us. We were spared. But it was a rare phenomenon for here. Our worst weather normally comes with the arrival of Winter. However, this storm knocked out power to over 300,000, took the roofs off of whole buildings, and killed 8 people, last I heard.
