SIOUX FALLS, S.D. - A flash flood warning has been issued for O'Brien County, Iowa, set to expire at 3:30 a.m. today.
National Weather Service Doppler Radar indicated thunderstorms with very heavy rainfall across the warned area. Rainfall of an inch and a half to two inches has already fallen across much of the area, and more rain will continue to move northeast in the next few hours.
Runoff from this rainfall will cause flash flooding to occur.
Additional rainfall amounts of three quarters to an inch and a quarter are possible, which will greatly exceed the capacity of the already-soggy soil.
Excessive runoff will cause flooding of small creeks and streams, highways and underpasses. Additionally, the National Weather Service stated, country roads and farmland along the banks of creeks, streams and other low-lying areas are subject to flooding.
People are warned to be especially cautious at night, when it is more difficult to recognize the danger of flooding. If flash flooding is observed, people should act quickly, avoid entering the water and try to turn around and move up to higher ground to escape flood waters. The National Weather Service warned people not to stay in areas subject to flooding when waters begin to rise.
