Snow and quickly falling temperatures have combined overnight to leave many roadways covered in ice Monday morning.

A Colorado low pushed through the province on Sunday, leaving piles of snow in parts further north, including the Parkland and Northern Manitoba. Much of western Manitoba was under a snowfall warning throughout Sunday afternoon

Further south mild temperatures and high winds pushed the system through. While snowfall amounts remained low in the Winnipeg region and many other areas, falling temperatures have resulted in icy road conditions.

The Trans-Canada Highway's westbound lanes were closed just west of Portage la Praire for a couple of hours on Sunday evening due to a serious collision at the intersection of Highway 16. Later, the westbound lanes were closed at the Portage la Prairie bypass due to poor conditions. Both stretches of the highway have since reopened.

Many highways are showing ice-covered sections of roadway throughout the province, and some school divisions have decided to cancel buses. As of 6:40 a.m. Mountain View, Swan Valley, and Turtle River school divisions say their buses are not running.
