Wind chill warnings remained in effect and school buses were cancelled Thursday as frigid air continued to linger over Saskatchewan.

Environment Canada says temperatures dipped below -30C across the province, but with the wind chill, it felt as cold as -46C.

The agency warns frostbite on exposed skin could occur in less than 10 minutes.

The brutal cold prompted Prairie Valley School Division to cancel all buses. Meanwhile, buses weren’t running in Moose Jaw’s Holy Trinity Catholic School Division.

Wind chill values were expected to ease by mid-day Thursday as temperatures warm slightly and the winds die down.
