Overview Rating tornadoes is essential for understanding their power, improving building codes, and issuing warnings. Today, the Enhanced Fujita (EF) Scale is the standard. It replaced the original Fujita (F) Scale in the U.S. (2007) and is used in other countries with minor adjustments.

❌ 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).

: 8/10 – Effective but needs continuous updates and public education about its limits. Would you like a shorter version, a comparison with other scales (e.g., TORRO), or a list of proposed improvements?
