Drayton Valley, Devon, Rimbey and Pigeon Lake areas were under a tornado watch Sunday evening, as Environment Canada meteorologists tracked a severe thunderstorm.
The agency also issued a tornado watch for Rocky Mountain House, Crimson Lake and other parts of Brazeau and Clearwater counties.
The advisories come as heat and thunderstorm warnings continue for most of central and south Alberta.
A tornado can produce strong wind gusts, hail the size of ping pong balls and heavy rain. Environment Canada has a list of tips if a tornado warning is issued for your area.
“Go indoors to a room on the lowest floor away from outside walls and windows, such as a basement, bathroom, stairwell or interior closet,” Environment Canada says.
People are advised to leave mobile homes, vehicles, tents, and other free-standing shelters and take refuge in a building.
A landspout tornado was spotted east of Edmonton in early June. Funnel clouds can appear with little or no warning and should be treated serious, the agency warns.
