(Sioux Falls, South Dakota) In Sioux Falls, South Dakota, Matthew Dux, Lead Meteorologist with the National Weather Service, tells KSOM/KS95 News that heavy rainfall of a foot or more across many parts of northwest Iowa has caused historic flooding.
Dux mentioned that the heavy rainfall has set numerous river flood records in the state’s northwest region. Starting last Wednesday, five to ten inches of rainfall drenched the Lakes area, with five to six inches falling within 12 hours. Rock Valley, Iowa, received six to 12 inches of rainfall, while areas near the Big Sioux River, just across the border from northwest Iowa, saw 12 to 14 inches of rain.
Dux updated us that some rivers are cresting. Still, the water will take a few days to recede, especially in residential and low-lying areas surrounding the rivers in northwest Iowa. Dux says there are numerous road closures in this region due to flooding.
