Wind chill warnings are in effect across much of southeastern Saskatchewan as a frigid blast of Arctic air hits the province.

Environment Canada says temperatures will hover around -40C with the wind chill Wednesday morning.

Regina, Fort Qu'Appelle, Estevan, Weyburn, Yorkton, Moosomin and Carlyle are among the communities under the wind chill advisory.

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