OMAHA, Neb. (AP) – North Platte is preparing for record flooding even as most snowmelt from Wyoming has yet to swell the North Platte River.

Lincoln County emergency manager Jim Nitz says the city is has surpassed record flood stage but the real problems could start with heavy mountain runoff.

University of Nebraska-Lincoln climatologist Al Dutcher says if the weather over the Rockies stays cool, snow will melt slowly and lessen the risk of flooding. But, he says, if there are warmer temperatures over the Rockies or heavy rain in the river basin it will be hard for reservoirs in Wyoming and Nebraska to hold all the runoff.

Reservoirs have been releasing water to make room and avoid heavy flooding when the snow starts melting. That’s contributing to high water in North Platte.
