Iowa communities along the Mississippi River will most likely see major flooding this spring.
A National Weather Service flood outlook released last week shows an over 50% chance of extensive inundation all along the state’s eastern boundary. Probability of moderate flooding is at 95% in most areas. Western Iowa faces lower, but still significant risk.
Heavy precipitation in 2019, still-saturated soils and heavy snowpack to the north contribute to the elevated flood risk.
Radio Iowa reported that Gov. Kim Reynolds said official are coordinating with local emergency management teams. Reynolds said the Army Corps of Engineers is releasing water already to make room for melted snow to the north.
Last summer’s Mississippi River flooding was the longest in recorded history, lasting nearly 200 days. A coalition of river city mayors estimated damage to be over $2 billion along the length of the river.
