On average, only about 1-2% of thunderstorms produce tornadoes. Tornado formation is a complex process that requires specific atmospheric conditions to be met, which are not present in most thunderstorms.
No. Only the Sim City games have Tornadoes.
Main averages 2 tornadoes per year.
Usually none. A survey of tornadoes in the late 20th and early 21s centuries show that only about 2% of tornadoes in the US ever kill anyone. Of the tornadoes that do kill, most only kill 1 person. Tornadoes with death tolls in the dozens are rare.
Tornadoes do not occur in Miami every year. Since 1950 Miami has had 27 tornadoes, which suggests an average of a little less than 1 tornado every 2 years.
A little more than 1% of tornadoes are rated F4 and F5 with F5 tornadoes being less than 0.1%
There were 16 tornadoes in Nevada in the years 2000-2010
Yes. It it fairly common for hurricanes to produce tornadoes when they make landfall. Therefore, any state that can get a hurricane could get a hurricane-spawned tornado. Some states, notably in the far northwest, will rarely if ever be affected by either tropical cyclones or by tornadoes, because the weather systems there are not conducive to their formation. The state of Alaska has had only 2 confirmed tornadoes over the last 65 years and only post-tropical cyclones.
There were 2 tornadoes in New York in 2008.
Since official record began in 1950 through 2013, Washington has recorded 109 tornadoes. The actual number of tornadoes is likely higher, as we missed many of the weaker tornadoes early in this period.
Hurricane Hugo produce 3 tornadoes. 2 rated F1 and 1 rated F0.
Only by a technicality. Most tornadoes do not actually kill anyone; only about 2% of tornadoes are killers. Only a handful of people have been killed by dust devils, but that still means there have been a few dust devils with a death toll of 1, while there have been many tornadoes with death tolls of zero. Aside from that, though, tornadoes are deadlier. Dust devils are far more common than tornadoes, but only a handful of people have been killed by them, and injuries generally only occur once every few years. By contrast tornadoes kill dozens of people and injure hundreds in a normal year.
