Storm restoration across Ogle County

Ogle County sits in prime northern Illinois severe weather corridor, making it one of the state's most active counties for tornado and wind damage. The April 2015 EF4 tornado that tore through Rochelle and Fairdale was the strongest tornado in northern Illinois in 25 years, killing two and injuring 22. Derechos are a recurring threat: the July 2024 event produced measured gusts of 101 mph in the county, and the August 2020 derecho caused enough structural damage in Forreston to trigger a disaster declaration. Large hail accompanies many of these supercell and squall-line events, and the county also faces significant winter storm exposure with ice events and heavy snow common from November through March due to its position south of Lake Michigan's influence yet fully open to Arctic air masses from the northwest.
