A heat dome is forming over Alberta, prompting widespread weather warnings and the activation of the City of Edmonton’s extreme weather response. “Another upper ridge in the jet stream will lead to hot, stable and stagnant conditions for much of Alberta for the near future,” Global Edmonton chief meteorologist Jesse Beyer said.
Environment Canada issued heat warnings Wednesday for a large swath of the province, from south of Calgary to north of Athabasca, as well in the Grande Prairie and Peace River regions of northwestern Alberta.
Heat warnings are issued when very high temperature conditions are expected to pose an elevated risk of heat illnesses, such as heat stroke or heat exhaustion.
Temperatures reaching 29 C combined with overnight lows near 14 C will begin Wednesday, continuing Thursday and potentially into the weekend.
