Yes. Generally speaking a tornado, even an F5, spares more people than it kills.
For example, on May 4, 2007 an EF5 tornado (essentially the same as an F5) destroyed 95% of Greensburg, Kansas, a town of about 1,600 people. Due to excellent warnings the death toll was limited to 11.
Yes, People have survived inside the funnel of a tornado, especially in weaker tornadoes.
Yes. People have survived such encounters. However, most do not.
Yes. Though you are unlikely to survive if you don't take shelter, people have survived in buildings that have been struck by F5 and EF5 tornadoes. One advantage is that an F5 tornado only produces F5 damage in small portions of the overall path.
It is unlikely. There has never been a recorded F5 tornado in Colorado.
No. Florida has never recorded an F5 or EF5 tornado.
Tornadoes fluctuate in intensity. An F5 tornado is only at F5 strength for part of the time it is on the ground.
The most recent F5/EF5 tornado was the Moore, Oklahoma tornado of May 20, 2013.
The rarest rating for a tornado is F5.
The Waco tornado was an F5.
No. There has never been an F5 tornado recorded in Colorado. It has had a handful of F4 tornadoes.
Any tornado can be dangerous. An F5 tornado is extremely dangerous. Hit by the full force of an F5 tornado, even the strongest houses will be swept away. Many F5 tornadoes are quite large, capable of leveling whole neighborhoods and killing dozens in a matter of minutes.
To date there have been no F5 tornadoes in the Freedom area since 1950. If you are referring to the 1984 tornado, it was an F4.
