A warning of a possible tornado has been replaced with a watch by Environment Canada for some southern Alberta communities just north of Calgary. Environment Canada started tracking a severe thunderstorm at 7:14 p.m. "that is possibly producing a tornado." "Damaging winds, large hail and locally intense rainfall are also possible," the national weather agency said on its website. Take cover immediately, if threatening weather approaches.
