Bad weather is rolling into Alberta.

Environment and Climate Change Canada (ECCC) on Thursday issued snowfall alerts for two swaths of central and southern Alberta, forecasting 15 to 20 centimetres of snow from Whitecourt and Edson southeast to Medicine Hat.

The agency said blowing snow could cause poor visibility and make travel challenging.

Mounties in both Sylvan Lake and Blackfalds alerted the public about icy and low-visibility areas, citing an increase in collisions due to road conditions and asking commuters to take extra precautions.

The snow is expected to taper off Thursday evening, according to ECCC. Saturday is expected to be the coldest day of the weekend, with a high of -11 C. Overnight temperatures are supposed to dip to nearly -20 C.

Edmonton is also activating its extreme weather response until 9 a.m. Monday to support vulnerable people.
