Hey Siouxland friends,
The flooding risk today is extreme in some areas, and I wanted to make sure all of you are aware of the situation.
Some areas in Siouxland received as much as 10 inches of rain in the last 24 hours, with substantially more rain possible today. In the worst case scenario, this could result in record flooding on the Rock River and major flooding along the Sioux River. This also could result in multiple roads across NW Iowa and SE South Dakota becoming impassable or even washed out.
Please avoid travel this evening in Lincoln/Lyon counties and other heavily flooded areas. If you know people in these areas and especially near the rivers, please make sure they are aware how dire the situation is. Personally, if I lived in Sioux or Rock River flood plains I would be evacuating or preparing to at this time.
