Warnings (In effect)

Snowfall warning in effect

Lake Winnipegosis

Issued 11:01 PM CST 17 January 2022 Heavy snowfall moving into Manitoba tonight.

A low pressure system approaching from Alberta will track across the eastern prairies tonight. Ahead of this system, heavy snow is forecast to fall across much of southern Manitoba tonight.

In general, 10 to 15 cm in total is expected over most of the region. However, communities in the Manitoba Parklands could see total accumulations approach or locally exceed the 20 cm mark by the time this system moves on.

The snow will abate over western Manitoba later Tuesday morning with the Red River Valley and points east following Tuesday afternoon.

Strong, gusty northerly winds will follow the snow on the back side of this system Tuesday afternoon. Gusts in excess of 70 km/h are possible downwind of Lake Manitoba, the south basin of Lake Winnipeg, and over most of the Red River Valley. The combination of the freshly fallen snow and gusty winds will produce blowing snow that will severely hamper visibilities on highways. In addition, wind gusts could be closer to 90 km/h over the ice-covered lakes with blizzard conditions possible during the afternoon. Blizzard conditions are possible in portions of the Red River Valley Tuesday afternoon as well. Gusts will begin to diminish Tuesday evening prompting better visibilities by Wednesday morning. Continue to monitor your local forecast in the event warnings are upgraded as the event draws closer.

Lastly, an arctic ridge of high pressure behind this storm system will bring a return of bitterly cold temperatures to the region, notably overnight Tuesday into Wednesday. Wind chill values will likely approach the minus 40 mark once again before temperatures moderate somewhat to end the week.

Be prepared to adjust your driving with changing road conditions. Rapidly accumulating snow will make travel difficult. Visibility may be suddenly reduced at times in heavy snow. If visibility is reduced while driving, turn on your lights and maintain a safe following distance.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to or tweet reports using #MBStorm.
