The strongest tornadoes occur the least often. Only a few percent of tornadoes are rated EF3 or higher. Less than 1 in a thousand receive an EF5 rating.
Tornadoes are more common in areas with warmer climates than those with cold ones.
Isolated tornadoes are tornadoes that do not occur in association with an outbreak. The tornado is generally the only one produced by that weather system or one of only a few scattered ones.
They don't. Tornadoes do occur in New York, but they are relatively rare. The regions cool climate and less-than ideal setup of wind shear and instability means that tornadoes, especially strong ones, don't occur often.
Tornadoes can occur and kill any time of day. Most tornadoes though, especially the strong ones that result in the most deaths, occur in the late afternoon or early evening. Tornadoes are more likely to kill after sunset as they are difficult to see.
Yes. Tornadoes, some of them devastating, can and do occur in Ontario. Two notable ones are the Windsor F3 tornado of April 3, 1974 Barrie F4 tornado of May 31, 1985.
Yes. On average Michigan is hit by about 15 tornadoes per year. Most of these tornadoes are weak, but strong ones do occur. Three tornadoes in Michigan history were strong enough to be rated F5.
Weak tornadoes are often about 5,000 feet tall while very strong ones can be 15,000 to 20,000 feet tall.
Yes, there are. There have been pretty strong ones too.
Although Florida has a very high concentration of tornadoes, they generally are not as strong or as destructive as the ones that occur in Tornado Alley. For example, since official records began in 1950 Florida has had 2 F4 tornadoes and no F5 tornadoes. By comparison Oklahoma has had 57 F4 tornadoes and 6 F5 tornadoes.
No. Usually the larger tornadoes are the stronger ones, but not always. There have been a few small but very violent tornadoes as well as large but fairly weak ones.
Quite often, yes. Once formation starts a tornado can develop in a matter of seconds. Most tornadoes, except for ones that are large or slow-moving, usually do not affect a given spot for more than a few seconds and even a mile wide tornado moving at average speed will only affect a location for about two minutes before moving on. That said, some tornadoes, especially very strong ones, can persist for well over an hour.
Tornadoes do not have names, hurricanes do. Tornadoes are often referred to by the places they hit. Some notable ones include the Miami tornado of 1997, the Kissimmee tornado of 1998, and the Groundhog Day tornadoes of 2007.
