Compared with many other weather phenomena, tornadoes are rather small and short-lived. This means that slight variations in the atmosphere, ones that are difficult impossible to detect, can affect where and when a tornado will strike. Even when we can detect small variations, the atmosphere is very complex and chaotic, making it difficult to predict how a given value might affect what happens.
Tornadoes hit the U.S. every year.
Depends on where you are, whether you want to know how many tornadoes have hit the United States, or a single state, or even somewhere else.
Tornadoes hit the U.S. every year.
tornadoes hit very hard very hard
There were 129 tornadoes in Texas in 2009.
That is impossible to know. Although it is not unlikely that there will be a few more tornadoes this year, and there will certainly be tornadoes next year, there is no way of knowing where or when they will hit.
A total of 9 tornadoes hit California in 2011.
Yes, Georgia averages 31 tornadoes per year.
33 F3 tornadoes have hit Florida since 1950.
Yes. Tornadoes can and do hit southern Ontario and have even hit the Toronto area.
Not very. On a time scale of hours to days were can assess what general areas will be at risk for tornadoes, but we don't know what locations will be hit. On a time scale of minutes we can detect tornadoes and their precursors, but most of the time we can't tell where a tornado will touch down, how hard it will hit, or if it will change course.
Tornado alley is the main striking point for tornadoes.
