Severe Storms Summary July 17th, 2019

Event Summary: July 17, 2019

A large complex of showers and thunderstorms progressed across southeast Iowa, west central Illinois and northeast Missouri this afternoon. Storms became severe as they moved southeast, and produced damaging wind gusts up to 70 MPH at times. These winds caused damage to roofs, carports, sidings and uprooted several trees in Stockport, Wayland and Burlington. In addition, torrential rainfall amounts of 1-2 inches were reported, and led to brief flash flooding in Keokuk.
