An F1 is a moderate tornado having wind speeds of 117-181 km/h (73-112 mph). It may cause moderate damage, peeling off roofing, pushing mobile homes off their foundations, and pushing moving automobiles off the road.
Estimated wind speeds for an F1 tornado on the original Fujita Scale are 73-112 mph. These were found to be inaccurate, though, and were adjusted to 86-110 mph for an EF1 tornado.
The scale runs from F0 (not very bad at all) F5 (incredible destruction) so an F1 would be considered a relatively weak tornado.
Yes. There was an F1 tornado in Cahokia mounds on October 6, 1955..
Yes. Wolcott was hit by an F1 tornado on July 3, 1996.
Tornadoes fluctuate in intensity. An F5 tornado is only at F5 strength for part of the time it is on the ground.
F1 tornadoes can kill, but they rarely do. So an F1 tornado is unlikely to kill you, but you should still take safety precautions to reduce your risk, especially since you can't tell how strong a tornado is before it hits.

Yes. F1 tornadoes rarely kill, but deaths have been recorded. In all they account for about 4% of tornado deaths in the United States.
In most cases an F5 tornado will be larger than an F1. However, tornado ratings are a measure of the strength of a tornado, not its size. F5 is the strongest category, and such tornadoes are usually very large, but a few have been fairly small. Conversely, F1 is the second lowest rating (F0 is the lowest) and such tornadoes are generally small, but some have been huge.
No. For one thing, Fujita (F) scale ratings measure the strength of a tornado, not its size. F1 is the second weakest rating a tornado can get (F0 is the weakest). Weak tornadoes such as this are generally small, but occasionally can be large. The highest rating a tornado can get is F5.
Yes. Newport, Arkansas was hit by an F0 tornado in 1992 and an F1 tornado in 1999.
Yes. There was an F1 tornado in Cahokia mounds on October 6, 1955..
F1 winds speeds are 71-112 miles per hour.
Yes. Wolcott was hit by an F1 tornado on July 3, 1996.
An F1 tornado can break windows, strip the surface from a roof and heavily damage a mobile home. Barns will likely be destroyed. Poorly secured roofs may be torn off.
In most cases an F1 tornado does not have that much energy and soon runs out and is more easily disrupted, though a few F1 tornadoes have had long damage paths. By contrast an F5 tornado will generally have several orders of magnitude more energy to release. Additionally, such a strong tornado could be considered more robust. A shift in the parent storm that might cut can F1 tornado's lifespan and thus damage path short, while the same shift might only weaken an F5 tornado somewhat.
