With average weather, communities along the Red River south of Winnipeg will likely have to close some — but not all — of their road access.
Along the Assiniboine River, a lot of agricultural land is expected to be flooded, and the communities of Melita and Souris may need extra protection if the weather turns bad.
Flooding is also expected near Brandon. Officials say super-sandbags will be placed in the city.
Forecasters predict water levels in Brandon will be lower than in 2011, when hundreds of homes were evacuated.
As always, the government says much depends on how quickly the snow melts in the coming weeks, and whether there is a big dump of snow or rain at the same time.
