2022 derecho storm was stronger, deadlier than first recorded

New data shows the wind speed at the Region of Waterloo International Airport was 147km/h, an increase from the 131km/h first recorded.

Comment from Candice Remillard-Scott:

Three cities across southern Ontario declared a state of emergency. At least twelve people were killed, mostly by falling trees. Power outages affected an estimated 1.1 million customers, and thousands were still without power a week after the storm. Hydro Ottawa described the damage dealt to its power distribution system as more severe than the 1998 ice storm. The storm was the sixth-costliest event in Canadian history. A storm survey from the Northern Tornadoes Project reported a severe downburst in parts of southern Ottawa. Its windspeeds reached up to 190 km/h (120 mph).
