Brandon, MB (CKLQ) - Environment Canada has issued an extreme cold warning for the entire province.
A large frigid Arctic airmass is moving into southern Manitoba, and it won't let go of the province until Thursday.
Widespread extreme wind chill values of -40 to -50 are expected tonight through to Thursday afternoon.
The winds, in the range of 20 to 30 km/h will also cause this past weekend's snowfall to drift and swirl on roadways, making travel more difficult overnight.
Manitoba Highways says will most roads in the region are clear, or partially covered, blowing and drifting snow are starting to limit visibility.
Environment Canada meterologist Natalie Hasell says people should curtail all outdoor activities, dress appropriately, and keep exposure to the cold down to short periods of time.
On the bright side, Hasell says Westman will be the first part of the province to see the retreat of the arctic air mass on Thursday.
