Rating Tornadoes __top__ <2025-2026>

This tool guides users through the official process of rating a tornado when wind speed data is unavailable (the most common scenario).

❌ No damage → no high rating – A violent tornado over open fields gets EF0–EF1, even if radar shows EF5 winds. ❌ Inconsistent application – Different survey teams may assign different ratings to similar damage. ❌ Rural bias – Urban tornadoes are easier to rate highly because more structures exist. ❌ No direct wind measurement – Almost all ratings are inferred from damage, not measured by anemometer (except rare cases like DOW radar). rating tornadoes
