Western Canada’s ‘heat dome’ named top weather story of 2021
Dave Phillips, senior climatologist with Environment Canada, has been compiling a Top 10 list of Canada’s weather events for more than two decades. Here are his picks for 2021:
1. Heat dome in Western Canada: At the end of June, a sprawling high-pressure ridge with incredible strength, height, scope and persistence compressed air enough to cook the atmosphere and dissipate clouds. Lytton, B.C., set an all-time Canadian high of 49.6 C. Days later, the town was destroyed in a wildfire.
2. Flooding in British Columbia: Nearly a month’s worth of rain poured into the Fraser Valley over one September weekend, flooding farms and nearly paralyzing Canada’s east-west traffic as it washed out major highways.
3. Drought: Years of dry weather culminated in drought across much of Canada’s agriculture belt. At one point, about 99 per cent of the Prairies grain region was classified as a drought scene.
