Episode Narrative Thunderstorms with extremely heavy rain developed along a stationary front and moved from northeast Iowa into northwest Illinois. Some locations measured 5 to 7 inches of rainfall, causing localized flash flooding and pushing numerous creeks out of their banks. Yellow Creek in Stephenson County was particularly hard-hit.
Pushing numerous rivers and creeks to bankfull or even out of their banks, this round of rainfall further set the stage for the extreme flooding that developed with the next round of storms later that night.
Event Narrative Heavy rains of 3 to 9 inches fell across Jo Daviess County during the late evening of July 22 and through the morning of July 23 resulting in flash flooding of much of the county. At 315 am CDT, water was over Highway 20 near Galena and Highway 35 near East Dubuque. Apple River overflowed its banks due to the flash flooding. In Elizabeth, water was flowing out of manhole covers. In addition, Lone Street and Apple River Road were closed due to the flood waters. At 940 am CDT, water rescues were in progress in Elizabeth. Several roads were closed due to flooding.
