Hancock County sits in west-central Illinois along the Mississippi River, placing it squarely in the upper Midwest severe weather corridor. Tornadoes are a documented recurring threat: the county has recorded EF1 and higher events including a violent F4 in 1995 and two EF1 tornadoes in a single evening in April 2026, with large hail up to 3.00 inches accompanying those storms. Fast-moving derecho and straight-line wind events regularly push 60-73 mph gusts across the county, downing trees, snapping utility poles, and damaging roofs and outbuildings. Mississippi River flooding is a persistent hazard for the river-corridor communities of Hamilton, Warsaw, Dallas City, and Nauvoo, with flood stages at Burlington and Gregory Landing directly affecting Hancock County; winter ice storms and heavy snow add a seasonal dimension that stresses roofing, gutters, and siding across all municipalities.
