Manitoba Transportation and Infrastructure has announced the overland flood warning for southern Manitoba has been extended until midday Tuesday.

Meanwhile, flood warnings and watches have been issued for southern Manitoba.

A flood warning remains in place for the Red River from Emerson to the Floodway Inlet and for the La Salle River. A high water advisory for the Whiteshell Lakes is in effect.

Manitoba Transportation and Infrastructure is reporting that water levels on most tributaries in the Red River basin and along the Red River main stem are rising quickly in response to the weekend rainfall and will continue to rise over the coming days. Daily average temperatures around zero is slowing down the melting of the remaining snow. Daily average temperatures are expected to increase to above zero on Tuesday.

Provincial crews are deployed in a number of communities in the Red River Valley preparing for and implementing ring dike closures. A dike closure on Provincial Road 200 at the north end of St. Adolphe has started.

Provincial crews are also running pumping operations to facilitate internal drainage inside ring dike communities. Pumping operations are underway at Dominion City, Morris, Brunkild, Rosenort and St. Adolphe.

There is a risk of moderate flooding in the eastern region including the Roseau and Rat rivers and the Whiteshell Lakes area.

Meanwhile, according to the U.S. National Weather Service, the Pembina River at Neche has now reached major flood stage.

As of Monday morning the river was at 21.4 feet, and based on current forecasts, is expected to reach a peak of 21.5 feet Tuesday morning, remaining at that level until at least Thursday.

The last time the Pembina River eclipsed 21.4 feet at Neche was in 2017 when the river reached 21.63 feet. That led to the closure of the Neche/Gretna border crossing, as well as a partial dike closure at the border crossing south of Gretna.

up 5.44 feet at Grand Forks to 43.32 feet
up 3.23 feet at Drayton to 35.45 feet
up 3.30 feet at Emerson to 780.34 feet
up 3.41 feet at Letellier to 777.94 feet
