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.
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 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.
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.
Tornadoes are powerful and often destructive. They can be terryfying to those in their path, and devastating to those who lose their homes or loved ones.
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.
It depends on the tornado. For most tornadoes the fastest winds occur at the edge of the core. For other tornadoes, especially large and/or strong ones the strongest winds occur in the suction vorticies, which are like mini tornadoes moving within the main circulation of a tornado. Tornadoes with this feature are called multiple vortex or multivortex tornadoes.
Weak tornadoes are often about 5,000 feet tall while very strong ones can be 15,000 to 20,000 feet tall.
That can have different answers. There are 6 levels on the Fujita Scale ranging from F0 to F5 (EF0 to EF5 on the Enhanced Fujita scale). But these are only levels of intensity and do not divide tornadoes into distinct types. Type 1: also known as supercell tornadoes. These tornadoes, which form from the mesocyclone of a supercell, are the most common type and are generally the strongest. They are the only ones that can reach EF4 an EF5 intensity. On occasion these tornadoes can become very large. Type 2: also known as landspouts or waterspouts* depending on where they occur. These tornadoes most often form from developing thunderstorms. They are weaker on average than supercell tornadoes but on rare occasions can be as as strong as EF3. When they occur as landspouts they often produce a characteristic dust tube. Other tornado-like circulations such as dust devils, fire whirls and gustnadoes are not considered tornadoes. *Type 1 tornadoes can occur as waterspouts as well, though not as often as type 2. They are called tornadic waterspouts. Waterspouts are usually not officially counted as tornadoes unless they hit land.
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.
