A high water advisory has been issued for the Whitemud River from Gladstone, Man., to Lake Manitoba, with provincial flood forecasters worried about river ice jams in that area.

The advisory for the Whitemud is in addition to a high water advisory that remains in effect on Monday for the Assiniboine River from St.-Lazare to Portage la Prairie.

Rising levels in that section of the Assiniboine prompted provincial government officials to begin operating the Portage Diversion on Saturday night.

As well, part of Highway 5 was closed over the weekend because of water on the road. However, the water has receded and the highway is open to traffic again.

There's a silver lining to the unseasonably cold weather that has many people in southern Manitoba shivering and griping

The sub-zero temperatures are expected to slow down the spring melt and run-off, but forecasters warn that the cold weather may also increase the chance of ice jams on rivers.

The Red River has crested at Grand Forks, North Dakota, and is expected to reach Emerson, Man., on Thursday or Friday, according to the province.

Officials added that the Red from Emerson downstream to Winnipeg "remains within its banks along its entire length."
