• Environment Canada: Weather alerts for Manitoba

CBCManitoba meteorologist John Sauder is calling for moderate to heavy snow over southern Manitoba, including Winnipeg, starting Friday night andinto Saturday.

Sauder expects at least 10 centimetresof the white stufffor most of southern Manitoba, with the possibility of up to 15 centimetresby late Saturday. He's also warning of higher snowfall amounts in the Parklands region, where easterly winds over the higher terrain will increase the snowfall amounts.

"Drivers will want to be ready for some fairly challenging travel conditions through the day Saturday," Sauder said.

Sauder says snow is expected to accumulate rapidly over some locations and, while there's not a lot of wind involved, heavy snow may reduce visibility at times.

The snow is expected to start falling overnight Friday before easing up by Saturday evening.
