Brief tornado warning south of Calgary lifted, thunderstorm watches ended

A number of people have reported this funnel cloud touched down near the town of Nanton Sunday afternoon. Environment Canada has not made an official determination.

Calgary — Environment Canada has removed its weather advisories for the residents of Calgary and southern Alberta regarding potentially "dangerous thunderstorms" Sunday.

The agency first issued the watch at 8:13 a.m., saying there is a potential for storms to develop in the foothills at around noon. As the afternoon progresses, those systems are expected to move eastwards.

"Conditions are favourable for the development of dangerous thunderstorms that may be capable of producing strong wind gusts, damaging hail and heavy rain."

As of 10:30 p.m., all thunderstorm watches had ended.

At about 1:15 p.m., Alberta Emergency Alert issued a tornado alert in the Foothills and Willow Creek regions. Approximately 10 minutes later, the alert was called off.

Viewers did send in photos of what appeared to be a funnel cloud, possibly even a tornado, near Nanton, Alta.

"Very large hail can damage property, break windows, dent vehicles and cause serious injury. Remember, severe thunderstorms can produce tornadoes. Be prepared for severe weather. Take cover immediately, if threatening weather approaches. Lightning kills and injures Canadians every year," the bulletin says.
