Flooding seems certain for some along the Missouri River

Ohio River Flood Warning issued

He says the outlook is "grim" for western Iowans who live along the Missouri River below Sioux City.

"This is determined from the current snow melt and snow pack and if we get. we will be watching. if we get into a scenario where we will get warm weather and dry weather. that will lesson our potential for flooding", Jessica Brooks, a service hydrologist with the National Weather Service".

In 2019, 60.9 million acre-feet of runoff entered into the Upper Missouri River Basin above Sioux City - just short of the record 61 million acre-feet set in 2011. Some are still recovering, 11 months later.

The risks of major spring flooding on the Iowa River also are relatively low. Jessica Brooks, a hydrologist with the National Weather Service in the Quad Cities, said the entire north-central part of the country has extremely wet soil conditions, including the Dakotas, Minnesota and Wisconsin - the upper parts of the MS and Missouri River watersheds. According to the outlook, "forecast points on the Knife River and Spring Creek have near normal risks of reaching at least minor flood state" and that the "Heart and Cannonball Rivers along with Painted Woods, Hay, Burnt, Apple, Cedar, and Beaver Creeks are now considered at near normal risk for minor flooding".

Brooks said the Mississippi River forecast shows higher risks of spring flooding because of the vast snowpack in Minnesota and Wisconsin, where soils already are saturated. "The real threat for flooding will rely on getting some heavy spring rains, which is harder to quantify". The service plans to issue an updated flood forecast February 27 and March 12.
