Blowing Snow Advisory:
Issued at 07:34 Thursday 12 January 2017
Poor visibility locally near zero in snow and blowing snow is expected or occurring.
A fast moving cold front has swept across southern Saskatchewan overnight and southern Manitoba early this morning. Light snow and blowing snow will reduce visibilities to near zero in open areas for a few hours with the passage of this front as northwest winds gust as high as 90 km/h. Temperatures will drop back to minus 30 or colder behind the front with wind chills entering the extreme category. Visibilities will improve later this morning in southeast Saskatchewan and Westman. Improvement will be seen over the Red River Valley this afternoon as winds diminish.
Travel is expected to be hazardous due to reduced visibility. Road closures are possible.
Extreme Cold Warning:
Issued at 04:16 Thursday 12 January 2017
A prolonged period of very cold wind chills is expected.
A fast moving cold front produced light snow and blowing snow as it swept across southern Saskatchewan overnight and will do the same over southern Manitoba this morning. Behind the cold front, more extreme wind chills in the -40 to -45 range are expected as temperatures drop. Extreme wind chills redeveloped overnight in Saskatchewan and will redevelop throughout the day in Manitoba as the cold air deepens. Conditions will begin to moderate over western Saskatchewan Thursday night.
Extreme cold warnings are issued when very cold temperatures or wind chill creates an elevated risk to health such as frost bite and hypothermia.
