Expected Summer Floods Could Set Record

With rivers running above flood stage and soils saturated, forecasters have predicted the 2011 summer flooding season could rival the worst in U.S. history. In the “Great Flood of 1993,” record-breaking floods from April to August cost more than $25 billion in damages in at least nine states.

Due to current high water levels and soaked soil, just a small amount of rain could trigger more flooding in areas that have already seen record flooding this season, the National Weather Service reported. These factors indicate the flooding threat will continue through the summer, and potentially rival the flood of nearly two decades past.

“There is nowhere for any additional water to go,” Jack Hayes, director of the National Oceanic and Atmospheric Administration’s National Weather Service said in the NOAA statement. “While unusual for this time of year, all signs point to the flood threat continuing.”

NOAA’s Climate Prediction Service has forecast above average rainfall in already-vulnerable areas of the upper Midwest and Northern Plains throughout July, and for much of the region in coming months. Rising temperatures over the Rockies will add to the flood threat, releasing water from the remaining snowpack.

The highest flood risk areas include regions in North Dakota, Minnesota and Iowa; the Lower Missouri River regions from the Nebraska and South Dakota border through Missouri to the Mississippi River; tributaries to the Lower Mississippi in North Dakota; the lower Ohio River Valley; and the East and West of Rockies, including Colorado, Wyoming, Nebraska, Montana and Utah.

The Federal Emergency Management Agency is currently providing federal disaster assistance to Missouri, North Dakota, Iowa, Kansas, Nebraska, Montana and South Dakota.
