Enhanced Fujita Tornado Damage Scale

IMPORTANT NOTE ABOUT F-SCALE WINDS: Do not use F-scale winds literally. These wind speed numbers are estimates and have never been scientifically varied. Different wind speeds may cause similar-looking damage from place to place; even from building to building. Without a through engineering analysis of tornado damage in any event, the actual wind speeds needed to cause that damage are unknown.
