June 28, 2017: Severe Storms Bring Significant Flash Flooding Near Rockford and Two Tornadoes

Overview

Wednesday evening, June 28, saw strong to severe storms redevelop and track across far northern Illinois. Some of the initial storms were supercells, producing a couple of EF-1 tornadoes over north central Illinois in Winnebago and Boone Counties. There were also areas of straight-line wind damage, including into Lake County Illinois.

The main story though was the significant flash flooding in Winnebago and Boone Counties due to 3 to 6+ inches of rain, mainly in less than four hours. The flash flooding was extreme enough to cause dozens of roads to be flooded and impassable across the two counties, include parts of the cities of Rockford and Belvidere. There were reports from Emergency Management of numerous vehicles stranded and drivers having to be rescued, as well as creeks over their banks including Kent Creek in Rockford.

Prior to the event, the NWS had been noting potential for heavy rain in Weather Story graphics for a few days in advance, and had issued a Flash Flood watch early Wednesday evening. This was shortly followed by a Flash Flood Warning at 8:24 p.m., updated to a Flash Flood Emergency at 9:32 p.m. given the flooding magnitude.
