Statements

4:25 AM CST Saturday 26 January 2019 Special weather statement in effect for areas in grey:


Severe Winter Weather approaches Saskatchewan. An intense low pressure system currently over the Pacific Ocean will come ashore Saturday morning and begin to affect Saskatchewan Saturday evening. Ahead of the system, warm Pacific air will gradually move in and bring above zero temperatures to southwestern areas today. Throughout the evening, the overnight, and into Sunday morning, a sharp line of mixed precipitation will be created with the zero degree line stretching between Meadow Lake and Regina. This area could experience snow switching over to rain and patches of freezing rain. By Sunday morning, the fast moving system will have moved completely into northwestern Saskatchewan and by early that evening, the northern and eastern grainbelt could see 10 or more centimeters of snow. The actual track of the system is still highly variable and the exact location of the heaviest snowfall is still to be determined. Additionally, this system will be accompanied by a vigorous cold front Sunday afternoon and evening that will sweep through southern Saskatchewan. Strong winds with gusts of 70 km/h and higher, falling temperatures, snow, and blowing snow will move through the province. The area of strongest wind will be southwest Saskatchewan which could see gusts of 90 km/h or higher. Widespread reduced visibilities in snow and blowing snow are likely behind the cold front. Please stay alert for updated bulletins, possible watches or warnings, and check the public forecast for more details.


Watches

4:32 AM CST Saturday 26 January 2019 Winter storm watch in effect for areas in yellow:


A developing low pressure system will bring heavy snow to the region tonight into Sunday, with total amounts of 10 to 15 cm expected. Snow, at times heavy, will begin to fall this evening and will be accompanied by freezing rain. Snow will end Sunday afternoon as the system exits the province. Rapidly accumulating snow could make travel difficult over some locations. Surfaces such as highways, roads, walkways and parking lots may become icy and slippery. Public Safety Canada encourages everyone to make an emergency plan and get an emergency kit with drinking water, food, medicine, a first-aid kit and a flashlight.

Winter storm watches are issued when multiple types of severe winter weather are expected to occur together.


Warnings

7:17 AM CST Saturday 26 January 2019 Extreme Cold Warning in effect for areas in red:


A prolonged period of very cold wind chills continues. The coldest wind chill values will be between minus 45 and minus 50. Extreme cold conditions continue this morning for northern Saskatchewan. Cloud and snow moving into the region today will allow this warning to be ended later this morning as temperatures rise. Watch for cold related symptoms: shortness of breath, chest pain, muscle pain and weakness, numbness and colour change in fingers and toes. Cover up. Frostbite can develop within minutes on exposed skin, especially with wind chill. Extreme cold warnings are issued when very cold temperatures or wind chill creates an elevated risk to health such as frost bite and hypothermia.
