High water on the Assiniboine River is moving from the Manitoba-Saskatchewan border south and east towards the city of Brandon.
The provincial government said Thursday that it's downgrading a flood warning for the Assiniboine River between the Manitoba-Saskatchewan border and the town of Virden.
The warning, which was issued on Wednesday, is now a flood watch for that area.
However, the province said the threat of flooding has increased between Virden and Brandon. A flood watch that was in effect there has been upgraded to a warning.
Flooding in those areas is expected to mainly affect agricultural land, the government stated in a bulletin.
Officials said cooler temperatures in the western part of the province have continued to slow the spring runoff, especially in the Parkland region.
But they warned that temperatures are expected to climb in the next couple days, which could increase melting and runoff and result in higher river flows.
Red River receding in North Dakota
In North Dakota, the Red River has crested in Grand Forks and is now receding, officials with the U.S. National Weather Service told CBC News on Thursday.
The Red crested at around 41 feet late Tuesday night in Grand Forks and at 33 feet in Fargo on Wednesday morning, according to preliminary figures.
Officials said as of Thursday, river levels were at 40.3 feet in Grand Forks and 32.2 feet in Fargo.
The crest is currently expected to reach Manitoba midway through next week, according to the weather service.
In Winnipeg, river levels at the James Avenue pumping station were at 18.3 feet on Thursday morning — down from 18.7 feet on Wednesday — and have stabilized because of the Red River Floodway and the Portage Diversion.
The province confirmed on Thursday that the west bank of the Portage Diversion has breached, spilling water onto surrounding land.
An official said the Assiniboine River east of the diversion is carrying 7,000 cubic feet per second (cfs) and that ice jams are a major threat at this time.
The province confirms it is raising and lowering the gates on the diversion to create wave action in an effort to break up the ice.
