On Sunday, Winnipeggers woke up to wet and windy conditions. At least one big tree has fallen over, blocking traffic.

But Environment Canada says the worst of the weather is on its way.

The heavy snow axis has shifted to the east, and will have an effect on the Portage la Prairie areas.

“The transition to snow has already happened over the Dauphin, Riding Mountain areas and we expect the transition to happen towards freezing rain and ice pellets over Winnipeg this evening, “said Justin Hobson, a meteorologist with Environment Canada.

The Colorado low is currently over northeast South Dakota and has spread an area of, at times, heavy rain over southern Manitoba.

Hobson said that although Colorado lows are often associated with winter weather, they can strike anytime of the year.

Commuters can expect traffic delays as conditions worsen. Slippery and icy conditions are already being reported in the Riding Mountain area.

The storm system is affecting southeastern Saskatchewan, southern Manitoba and will make its way to northwestern Ontario.
