SIOUX FALLS, S.D. (WNAX) – The first flood forecast of the year last week indicated that most rivers in eastern South Dakota have up to a 90 percent chance of major flooding this spring.

Lance Vandenboogart at the National Weather Service in Sioux Falls says they are also looking at longer range forecasts.

Vandenboogart says the outlook into spring is not favorable.

Vandenboogart says people should start preparing now.

Saturated soils and heavy snow cover in northern parts of the state are critical threats for major flooding.
