A winter storm passed through the state Monday and it dumped up to 40 centimetres of snow on some areas.
The snow packed a lot of water and has elevated the risk of flooding.
According to the U.S. National Weather Services' bi-weekly flood report for the Red River Valley, there is a 50% chance the Red River will reach 10.3 metres in Fargo and a 5 % chance it will make 11.64 metres.
That's a major increase over last month's predictions.
Flood levels are considered anything over nine metres.
Just south of the Manitoba-United States border in Pembina, the concern is just as high.
25 centimetres of snow fell in the region and that has the Pembina River elevated, with a flood level risk beginning early April.
Flood forecasts for Manitoba will be released next month.
