TIL about "derecho" storms that have no eye and move in a straight line (www.9news.com)

"The storm has no eye, and its powerful winds come across in a line. That can cause widespread overall damage and smaller pockets of severe damage.

To be classified as a derecho by the National Weather Service, the storms must have wind gusts of 57 mph or greater and wind damage from the storm must span at least 400 miles."

There was a nasty one that went through Ottawa in May 2022. Devastated the power grid, trees, widespread roof damage. A big house near me lost a 30x60 piece of roof.

No power at my house for 2 weeks.

Do not anger the derecho spirits...repent!

It's been over a year already? Goodness.

The storm ended up being the 6th most expensive natural desater in Canadian history https://ottawa.ctvnews.ca/mobile/may-21-storm-ranked-6th-most-expensive-natural-disaster-in-canadian-history-ibc-1.5948666?referrer=https%3A%2F%2Fottawa.ctvnews.ca%2Fone-year-since-derecho-in-ottawa-an-east-end-councillor-reflects-1.6408070
