Several areas in southern Saskatchewan are under tornado and severe thunderstorm warnings Saturday afternoon.

According to the Environment Canada website "meteorologists are tracking a dangerous thunderstorm that is capable of producing a tornado" in the R.M. of Calder including Calder and Wroxton.

Tornado warnings also exist for the areas of the R.M. of Cote including Kamsack, Togo and Duck Mountain Provincial Park.

The site said storm spotters have reported a possible twister north of Wroxton, which was moving to the northeast.

Areas between Kamsack and Wroxton are considered to be in the path of the tornado. 

Environment Canada is advising people to take cover in a sturdy, permanent building or underground area if threatening weather hits. Places such as vehicles, mobile homes, cottages, boats and tents are unsafe.

"If you see a funnel cloud, swirling debris near the ground, flying debris, or any threatening weather approaching, take shelter immediately," said the website.

A severe thunderstorm watches is also in place over the larger areas of Yorkton, Melville and Esterhazy.

There could be a potential for large hail and damaging winds.

People are being advised to check conditions on the Environment site for updates.
