Nebraska and Iowa officials have been keeping watch on an ice-covered portion of the Missouri River for any flood threat it could pose.
Woodbury County, Iowa emergency services chief Gary Brown says the ice situation near Ponca in northeast Nebraska is "something we're monitoring. It's nothing we're alarmed with at this point."
That could change with higher temperatures expected this weekend. If the ice breaks up and chunks float downstream, that could snag on something and jam the river channel, causing water to back up and flood the banks or raise tributary stream levels.
Dixon County, Nebraska emergency services director Shea Scollard says he hasn't gotten any calls yet from worried residents along the river.
