Why it's trending
The rapid issuance and cancellation of a red tornado warning, combined with risks of baseball-sized hail and severe thunderstorms near Edmonton, drove public concern and search interest in the storm's status.
Environment Canada issued a red tornado warning for parts of Yellowhead County, Alberta, on Saturday afternoon, later cancelling it as the threat diminished. A severe thunderstorm warning remained in effect, with the storm tracked west of Entwistle moving east at 45 km/h, according to the agency.
The alert warned of hail larger than baseballs, damaging winds, and intense rainfall. Environment Canada said the storm was capable of producing tornadoes, though they were no longer expected as of the 7:43 p.m. MT update.
The Weather Network reported that conditions — including moderate to high instability and strong wind shear — were favourable for supercell thunderstorms. Wildfire smoke was cited as a wildcard that could suppress storm development. The main hazards were very large hail up to golf ball size and possible tornadoes, especially west of Edmonton.
Residents were urged to take immediate cover if threatening weather approached. The storm system was part of a broader pattern of severe weather across Alberta, with hot temperatures persisting in the south acting as a cap on storm development.
