Heavy rain that fell across the state in mid-December led to river flooding at many locations across central and southern Iowa. The ground was already saturated from a wet fall, with new rainfall of one to 3 inches fell across the area in a two-day span. The heavy rainfall also allowed for many area streams and creeks to reach bankfull or go into flood. County roads across several counties were closed due to flooding as well.
