A line of severe thunderstorms hit Calgary on Sunday, resulting to power outages in some areas. The weather disturbance likewise gave off flash flooding to streets and into garages and basements in Chestermere.
Environment Canada issued severe thunderstorm warnings by 3 p.m. MT. over for Red Deer, Ponoka, Innisfail and Stettler, while an earlier storm warning had been cancelled for Calgary at 9:40 a.m. MT. According to the agency on its website, the dangerous thunderstorm is capable of producing to penny-sized hails and flooding rain.
The thunderstorm caused flash floods in parts of northeast Calgary early Sunday morning, as well as Langdon and Chestermere east of the city.
Donna Riopel told Global News she wasn’t prepared when a torrent of water almost overwhelmed her when she opened her main floor and basement.
“Literally, when I opened this door, whoooosh, I had to close it with all of my force. The only thing I can do when this was happening is say god bless, it’s a four level split, I still have two floors upstairs where I can keep dry,” Riopel said.
“A flash flood, within 45 minutes the whole entire basement is full, my basement is full of water and the whole backyard.”

Steve Bagley, Chetermere’s director of emergency management, described the thunderstorm as short, but “was intensely severe storm” because it was able to pour down a large amount of water that “overwhelmed our systems.”
Environment Canada cautioned residents on driving through flooded roads.
“Watch for possible washouts near rivers, creeks and culverts. Persons in low lying areas or valleys should watch for rapidly rising water and be prepared to move to higher ground,” the agency said. “Lightning kills and injures Canadians every year. Remember, when thunder roars, go indoors.”
Chestermere could have received over 150 millimeters of rain, weather specialist Brian Proctor said.
