The Enhanced Fujita (EF) scale classifies tornadoes based on the estimated wind speeds and the resulting damage to structures and vegetation. The scale ranges from EF0 to EF5, with each category reflecting a range of wind speeds and associated damage levels.
The most violent tornadoes on the EF scale are classified as EF5 tornadoes, which have estimated wind speeds of over 200 miles per hour (mph), specifically starting at 261 mph and can exceed 318 mph.
An EF3 tornado is categorized with estimated wind speeds ranging from 136 to 165 mph. It can cause severe damage, including the destruction of well-built houses and the overturning of large vehicles.
