@pango9102 Could you provide more information on the damage in the Wonder Lake area? Specifically, we would need to know what kind of damage occurred (was it just tree damage, or was there structural damage too?) and a more precise location (e.g. cross streets) for where it occurred. — NWS Chicago (@NWSChicago) Apr 4, 2026
