NEBRASKA CITY - The National Weather Service says rainfall over the last 48 hours, which was measured at 10 to 15 inches in some areas, is bringing destructive flooding in northwest Iowa..

As the rainwater makes it way to the Missouri River basin, flood warnings are being issued for the River from Plattsmouth to Kansas City. Flooding was already occurring along the river upstream of Omaha on Sunday.

The Missouri River is forecast to crest at 25.1 feet after midnight on Thursday. North First Street in Nebraska City will flood at a level of 23 feet. Highway 2 may begin to flood at 25.5 feet.

The river is forecast to fall below flood stage on July 3.

The U.S. Army Corps of Engineers at Omaha has activated its emergency operations center.

Col. Robert Newbauer, Omaha district commander, said the corps is providing all the assistance it can to reduce the threat to life and property.

Technical assistance is being provided to Buena Vista and Dickinson counties in Iowa.

Late Sunday, the corps was reporting that inflows into Gavins Point Dam appear to be peaking and the NWS is forecasting a dry day Monday for the upper basin.

The inflows into Gavins Point were reported at 35,500 cubic feet per second late Sunday from a peak of 40,000 cfs earlier in the day.

Because the inflows appear to be decreasing, releases at Gavins Point will be held at 24,000 cfs per second.

Action stage has been reached on the Missouri River near Blair and Plattsmouth and moderate flooding is forecast.

The Floyd River in Merill, Iowa, rose from 4 feet to 20.2 feet Sunday. The Big Sioux River above Hawarden rose from 17 feet to 39.9 feet on Sunday. The Big Sioux is expected to crest above 2019 levels.
