Environment Canada has issued a severe thunderstorm watch for much of central Alberta, including Calgary and Red Deer. It warns of the potential of "dangerous thunderstorms that may be capable of producing strong wind gusts, damaging hail and heavy rain."
Streets and underpasses in southwest Calgary became flooded from the heavy rain, while an intense hailstorm rained down on parts of the city. The Calgary fire department has responded to reports of flooded condo complexes in Sunalta.
Visitors enjoying the first weekend of the Stampede searched for cover as hail pelted the fairgrounds.
Flooding also caused delays on the C-Train system, according to Calgary Transit.
