Impact verdict

Medium impact. Materiality remains medium but is trending upward as corroborating mainstream coverage documents confirmed tornado damage across Illinois, Indiana and Iowa rather than only forecast risk. Urban exposure is concentrated in Chicago (IL), Des Moines (IA), Merrillville (IN) and Elkhart (IN), with confirmed impacts to homes, infrastructure and aviation operations. Hazard set spans tornado, destructive straight-line wind, and flood perils. Escalation to high would require official damage assessments indicating concentrated urban tornado losses or a major tornado outbreak striking additional major metros.
