Overview
|
Numerous severe storms tracked across eastern IA, northwest IL, and northeast MO during the afternoon and evening of April 17. Widespread wind gusts between 60-80 mph (isolated 80-100 mph), large hail up to teacup size, and several tornadoes were reported. The most significant damage occurred in Lena, IL where many homes and outbuildings were damaged, trees uprooted, and power lines downed by an EF2 tornado. Very strong straight-line winds also were documented in parts of the area. The NWS is close to finalizing their takeaways in collaboration with county emergency management and neighboring NWS offices. We appreciate your patience as we work through our post-event analysis. |
