August 2021	Thunderstorm Wind	Rockford	1 killed, 2 hurt	A tree fell onto a mobile home in the Riverview Mobile Home Park. Three occupants were rescued. One of the rescued, a 55 year old woman, died from her injuries.

September 2006	Flash Flood	Rockford	$20,000,000	Thunderstorms developed over southeast Winnebago County and eastern parts of the City of Rockford during the afternoon and evening of September 4th. The thunderstorms continued to redevelop over the same areas, as they pushed north and weakened. Some areas across parts of eastern Rockford received heavy rain for two to three hours. As a result, massive and severe flooding occured. Most of the flooding occurred in and around the Keith Creek Watershed.
