Snow drifts and wind chills as cool as -45 C are gripping the Prairie provinces where travel warnings are in effect in some areas and plows are trying to clear up to 25 centimetres of new snow in southern Saskatchewan.

A wind-chill warning is in effect for southern and central Saskatchewan, including Regina where gusts of 40 km/hr are creating wind chills of -45.

The overnight low in many areas of southern Saskatchewan is -35 without the wind, but warmer weather is on the horizon with a high of -4 in the forecast for Monday.

The storm moved into western Manitoba late Friday, dumping up to 10 centimetres of snow and causing a highway alert to be issued for the Trans-Canada Highway west of Brandon because of snow-packed and slippery roads with reduced visibility.

Although the storm is tapering off on the west side of the province, a snowfall warning is now in effect for southeastern Manitoba where 10 to 15 centimetres of snow is expected in some areas, tapering by evening.

The storm will be followed by another blast of cold Arctic air, bringing extreme wind chills of -40 by Sunday morning over western Manitoba and the Red River valley.
