Flood in Scott County, Illinois

Rain amounts of 3.00 to 5.00 inches in about a three hour period during the early evening hours, on already saturated ground, resulted in flash flooding across much of Scott County. Numerous streets in Winchester were impassable, as were numerous rural roads and highways in the county including parts of Illinois Route 106 which was closed in spots near Alsey. Additional rain of 0.50 to 1.00 inch during the early morning hours kept many roads flooded. Flood waters subsided by early afternoon on the 30th.

Heavy rainfall impacted central and southeast Illinois from April 29th into April 30th...creating flash flooding, which led to widespread areal flooding. Periods of thunderstorms with very high rainfall rates dropped 2.00 to 6.50 inches of rain across much of central and southeast Illinois from April 29th into early on May 1st. This rainfall, occurring on top of already saturated soils, created flash flooding in a number of locations. Numerous roads were closed due to high water...including portions of Highway 29 in Peoria where a mudslide occurred. Low pressure lifted into the Great Lakes on May 1st, pulling the persistent frontal boundary out of the area and bringing a temporary end to the rain. Even though the rain had stopped, high water continued to impact many rural roads across central Illinois, particularly those near creeks and streams. Persistent flooding issues occurred across Christian, Shelby, and Douglas counties...as well as along the Embarras River Basin in Cumberland and Jasper counties.
