Iowa Flooding More Storms on the Way

A strong low pressure system and associated cold front will track across the Central Plains and Midwest today bringing the threat of severe thunderstorms. Clusters of strong to severe storms are expected to develop, especially from Iowa through southern Minnesota today. A moderate risk of severe storms will exist across this region with the main threats of damaging wind gusts, hail and isolated tornadoes. There will also be a risk for heavy showers and storms, especially from Iowa through southern Minnesota and Wisconsin ahead of the front. Rainfall amounts of 1-3 inches are expected in this area with locally heavy amounts up to 3-5 inches possible. Saturated soil in this region will lead to the risk of flash flooding.

Severe storms (red) and heavy rain (green) will be possible across the Central Plains and Midwest today as a strong low pressure system and associated cold front move across the area. Isolated severe storms will also be possible across the Southeast as a weak front interacts with deep tropical moisture and strong daytime heating. Heavy rain is expected across the northern Gulf Coast today with 1-3”, isolated heavier amounts 3-5”. Hot and humid weather (orange) will continue across parts of the Southern Plains into the Ohio Valley with heat index values near or above 110ºF. Map: ImpactWeather

Speaking of flooding, Iowa has seen some very heavy rainfall over the past few days which have caused creeks and rivers to swell. The heavy rain the past few days across portions of central and eastern Iowa has caused flooding which has forced hundreds of residents to evacuate their homes. Cars have also been swept off the road and a 16-year-old girl was killed when the car she was riding in was swept away by flood waters. Remember it only takes 2 feet of fast-moving water to float a large vehicle or even a bus away. If you’re ever in a situation where the streets are flooded the best thing to remember is the old saying, “Turn around don’t drown.”

The recent rains also flooded the campus of Iowa State University as both the South Skunk River and the Squaw Creek rose above their natural boundaries. ISU spokesman John McCarroll said several campus buildings were closed but that campus housing was unaffected and the students should be able to move in as scheduled next week. Iowa State will start fall classes on August 23.
