Yes. F1 tornadoes rarely kill, but deaths have been recorded. In all they account for about 4% of tornado deaths in the United States.
Yes. Tornadoes of all intensities have injured and killed people.
F1 tornadoes rarely kill, and when they do the death toll is rarely higher than 1 or 2. However, the deadliest F1 tornado to occur in the U.S. since records keeping began in 1950 killed 16 people. The deaths occurred when the tornado capsized a boat on Pomona Lake in Kansas. A similar, but far deadlier case occurred in China in 2015 when an EF1 tornado capsized a cruise ship on the Yangtze river, killing 442 people.
Yes, on June 28, 1982 Fairfield, Alabama was hit by an F1 tornado. 1 person was injured.
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.
158 people were killed by the Joplin tornado. Another tornado on the same day killed 1 person in the Minneapolis area.
The Goderich, Ontario tornado of 2011 killed 1 person.
It is possible, but it is a very bad idea. An F1 tornado can carry dangerous debris and the winds can pick up and throw a person. Additional threats may come from the parent thunderstorm in the form of lightning and large hail. Finally, it is impossible to tell exactly how strong a tornado is before it hits and even then a tornado can strengthen rapidly.
The last known killer tornado, as of October 15, 2012 was an F2 in Wycinki, Poland that killed person.
The Hallam, Nebraska tornado only killed 1 person.
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.
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.
