The U.S.-Canada border crossing at Gretna has been closed temporarily due to overland flooding from the Pembina River in the United States.
The closure affects traffic along Highway 30 in Manitoba and North Dakota’s Highway 18.
Border crossings at Emerson, Tolstoi and Haskett remain open.
In North Dakota, the Renwick Dam on the Tongue River, a tributary of the Pembina, is in danger of overtopping or failing. The city of Cavalier, N.D. has been placed under an evacuation order.
Some eastern tributaries of the Red River, such as the Roseau and Rat rivers, are still rising but expected to remain well within their banks.
In a flood bulletin this afternoon, Manitoba Infrastructure and Transportation said heavy rains over the Victoria Day long weekend are continuing to produce extensive farmland flooding in areas that received more than 75 millimetres of rain.
Flooding is mainly affecting areas west of the Red River and south of Highway 23 in the rural municipalities of Rhineland, Stanley and Pembina. Flooding has also occurred further north in the RMs of Roland, Thompson and Dufferin.
