Storm restoration across Carroll County

Carroll County sits in the northwest corner of Illinois along the Mississippi River, placing it squarely in the corridor for Great Plains-originated severe weather. Tornadoes, large hail, and damaging straight-line winds from derechos are recurring seasonal threats, with the August 2020 Midwest derecho producing estimated gusts of 100 mph near Forreston and an EF1 tornado striking near Pearl City in April 2026. Spring storm systems regularly produce flooding along Highway 84 and the Mississippi River bottomlands, and the county's elevation changes create localized mudslide risk during intense rainfall events. Winters are severe: Mount Carroll holds the all-time Illinois state record low of -38 F set January 31, 2019, and the county experiences heavy snowfall, ice storms, and freeze-thaw cycles that compound roof and structural damage sustained during storm season.
