The rains that soaked the Omaha area on Saturday heightened concerns about flooding in the region.
Parts of eastern Nebraska had up to 2.5 inches of rain, while areas of southwest Iowa received more than an inch, said Rick Chermok of the National Weather Service.
The rains fell in a six-hour period and tested Omaha’s flood control efforts along the riverfront. Storm drains overflowed and some north downtown businesses were flooded.
Authorities in Harrison County, Iowa, were dealing with a levee breach and rising Missouri River floodwaters.
Emergency officials urged people to evacuate Saturday following the breach one mile south of mile marker 2 on U.S. Highway 30 near Missouri Valley.
Water threatened to overtop Highway 30, which connects Missouri Valley with Blair, Neb.
The situation was deteriorating Saturday night and the highway could close with no advance notice, the Iowa Department of Transportation said. Nebraska officials said they would close the Nebraska side of Highway 30 if that happens.
Floodwaters were expanding into farmland and the De Soto National Wildlife Refuge near Missouri Valley, said Larry Oliver, Harrison County emergency director.
