How Montana compares nationally
Ranked by SPC verified storm reports (wind, hail, tornado) across all 50 states over the last 12 months. Severity-weighted index scores each report by hazard (tornado ×20, hail ×4, wind ×1) so a single derecho's flood of wind reports doesn't outweigh tornado outbreaks. Recalculated daily as of Sep 12, 2026.
