Storm damages shopping mall in central Alberta, downs trees, power lines

RED DEER, Alta. — Trees toppled and power lines went down as a severe storm swept through parts of Alberta.

Wind speeds upwards of 110 km/h were reported and people who live in the Red Deer and Innisfail areas say the force of the wind felt like a hurricane.

The City of Red Deer issued a tweet on Tuesday night saying there were no reports of injuries but the emergency operations centre had been activated.

The storm also uprooted trees in northwest Calgary as it blew through the city.

The owner of Red Deer's Little Ice Cream and Soda Shoppe, Greg Little, says the storm moved in fast and sounded like a train.

Little says there is damage everywhere he can see.

"It was scary, it was like nothing I have ever seen," he says.

Many people posted pictures of damage to social media, including part of a roof that blew off a store and landed on nearby parked cars.

Daelyn Hamill of Red Deer put up a picture of a giant spruce tree that had crashed onto the roof of his parent's home, urging people to "stay safe out there!"

One video showed scenes of people walking through a darkened Parkland Mall amid broken windows and light fixtures dangling from the ceiling, some wondering if they had been hit by a tornado.

Another photo showed a semi-trailer that had been pushed onto its side by the winds on the highway between Innisfail and Penhold.

Town officials in Innisfail were also reporting widespread power outages and that the roof had blown off the town's curling rink, though an initial assessment said there was no structural damage to the building.

Environment Canada issued a severe thunderstorm warning for parts of Alberta on Tuesday evening.

The weather agency was tracking a line of storms and said that they could produce strong winds, large hail stones and heavy rain.

Weather experts from Environment Canada say the storm developed in the Pigeon Lake area and that the Red Deer Airport recorded wind speeds as high as 111 km/h.

Fortis Alberta says about 21,000 of its customers between Calgary and Edmonton lost power because of the storm and crews are working to restore service.
