Storm restoration across Greene County

Greene County sits in western Illinois along the Illinois River valley, placing it squarely in the path of severe weather systems that track northeast across the Midwest. The county has recorded at least 20 documented tornadoes including multiple F4 events, and its position in the western Illinois corridor exposes it to derechos, large hail, and straight-line winds exceeding 70 mph during warm-season supercell and squall-line events. The Illinois River and its tributaries create significant flash-flooding and river-flooding risk, particularly during heavy spring rainfall; 99 of Illinois' 102 counties have been declared presidential disaster areas for flooding since 1981, and Greene County's low-lying bottomlands amplify that exposure. Winter brings recurring ice storms and heavy snow events that damage roofs, gutters, and siding across all nine municipalities.
