Flash Flood in Peoria County, Illinois

Thunderstorms moving over the same areas multiple times resulted in 3.00 to 7.50 inches of rain in the northeast half of Peoria County during the early morning hours of June 24th. The locations that experienced the greatest impacts from the flooding included Princeville, Rome, Mossville, Dunlap and the north and west portions of the city of Peoria. Multiple roads were closed, motorists were stranded and homes were flooded. Several state highways were impassable, including Highway 6, 29, 40, 78, 90 and 91. A box culvert was also damaged on a rural road outside of Princeville. This was the second major flash flood to impact Peoria County since mid-April. Most of the flash flooding subsided by mid-afternoon.

A slow-moving cold front triggered showers and thunderstorms across north-central Illinois during the morning of June 24th. Due to the very humid airmass in place across the region, the storms were efficient rain-producers, with much of Stark, Peoria, and Woodford counties picking up 3 to 5 inches of rain. As a result, flash flooding of many low-lying areas was reported. In addition to the heavy rain, a few of the cells produced 50 to 60 mph wind gusts.
