Flood — Harrison, IA

Mar 13, 2019

A 971mb bomb cyclone moved out of the central Rockies on Wednesday, March 13, 2019 and helped to create widespread, moderate to major, and in many cases historic, flooding across eastern Nebraska and western Iowa. From 4 to 15 inches of snow cover remained across the mid Missouri River valley, and the ground was frozen with existing frost depths of 15 to 23 inches. Warm temperatures allowed all of the snow to rapidly melt and record moisture allowed 1 to 2.5 inches of rain to fall over a 48 hour
