Cedar Rapids Gazette: Spring flooding again threatens both sides of Iowa, National Weather Service forecasters reported Thursday in the first of three predictions leading up to the season. The early outlook shows a 95% probability of major flooding again this year along the Mississippi River on the state’s eastern border. The Missouri River along the state’s western border faces an elevated risk of spring flooding. The forecast heightened concerns in areas of Iowa, Nebraska, Kansas and Missouri with levees that still have extensive damage from massive flooding last year.
