Impact verdict

Medium impact. MEDIUM: A tornado watch for the densely populated and heavily insured Chicago metro area indicates plausible severe convective storm losses to property and business interruption lines if tornadoes touch down in the urban footprint. Loss estimates are premature at the watch stage; severity remains dependent on unconfirmed touchdown reports and damage assessments.
