An EF5 tornado has an estimated wind speed of over 200 mph (miles per hour,) while an EF4 has wind speeds from 166 up to 200 mph. The scale approximates the intensity of a tornado. "F" stands for the Fujita Scale, with "EF" standing for the Enhanced Fujita Scale. Both rate tornadoes based on engineered wind estimates and damage descriptions. Both F4 and F5 tornadoes are ranked as "intense" and "violent," but the difference between the ratings can only be determined by Doppler Radar data and other technical meteorological measures. See the Wikipedia article linked below for further information and sources. In more detail, an EF4 tornado will level a well built house and blow away ones of with less integrity. An EF5 will wipe well built houses clean off their foundations.
We do not know. The Natchez tornado was in 1840, and it is hard to get reliable information from records that old. The tornado itself was probably an F4 or F5, which would put wind speeds in the range of 200 mph or more, but that does not indicate anything about how fast the tornado itself moved.
F3 and F4 refer to ratings on the Fujita scale, which measures the strength of a tornado based on the severity of the damage it causes. It has six categories ranging from F0 at the weakest, causing minor damage, to F5 at the strongest, causing total devastation. F3 on the scale indicates a strong tornado that will partially or mostly destroy well-built houses, but leave some walls standing. F4 indicates a violent tornado that will completely level well-built houses.
Note that tornado ratings are not based on size, and F5 tornadoes have been recorded at a wide variety of widths. One F5 tornado in Kansas was 2.2 miles wide. However, one F5 in Texas was less than a quarter of a mile wide, and narrowed to only 60 yards when it reach ed F5 strength.
There is not given size for an F5 tornado as ratings are based on damage rather than size. Typical F5 damage is well constructed houses blown clean off their foundations.
That depends on where the tornado is. Generally, tornadoes in the northern hemisphere rotate counterclockwise while those in the southern hemisphere rotate clockwise. There are more violent tornadoes in the horthern hemisphere, but that is mostly due to the fact that portions of the United States have an almost perfect setup for producing them. A small percentage of tornadoes rotate in the opposite direction from what is normal. These are called anticyclonic tornadoes (normal tornadoes are cyclonic). Many anticyclonic tornadoes are satellite tornadoes, and are generally weaker than the parent tornado that spawned them. Only one anticyclonic tornado has ever recieved a violent (F4 or F5) rating on the Fujita scale. It was an F4 that hit West Bend, Wisconsin on April 4, 1981.
F4 and F5 are the two strongest categories of tornado on the Fujita scale. A damage based scale which rates tornadoes from F0 to F5. An F4 tornado will reduce most houses to piles of rubble. An F5 tornado will completely annihilate almost any house and wipe it clean off its foundation. Winds in an F5 can exceed 300 mph.
No. There has never been an F5 tornado recorded in Colorado. It has had a handful of F4 tornadoes.
An F4 or higher tornado (the only higher rating being F5) is classified as violent.
To date there have been no F5 tornadoes in the Freedom area since 1950. If you are referring to the 1984 tornado, it was an F4.
Yes. Large F4 and F5 tornadoes have been known to destroy entire towns.
F4 and F5 are the two strongest categories of tornado on the Fujita Scale. The Fujita scale rates tornadoes from F0 to F5 by the severity of damage done. An F4 tornado will level most houses and strip the bark from trees. An F5 tornado, with winds than can exceed 300 mph, will completely annihilate a well built house and sweep it clean off its foundation. Cars and even houses can be thrown hundreds of feet.
Yes. F4 is the second strongest category on the Fujita scale, indicating an extremely powerful tornado that can completely level well-built homes.
There has never been a violent (F4 or F5) tornado recorded in California.
Oklahoma has had the most F4 and F5 tornadoes. Though it is tied with Texas, Iowa, and Alabama in terms of F5 tornadoes in the past 60 years.
There was an F5 that hit the Oklahoma city area in 1999, but it had weakened to F4 intensity by the time it hit Oklahoma city proper.
It is possible but quite unlikely. No F5 or EF5 tornado has ever been recorded in the State of New York, but there have been a few F4 tornadoes. One tornado in Massachusetts in 1953 was possibly an F5.
No. The highest rating a tornado can receive on the Fujita scale is F5. F4 is the second highest rating. Even then, while very strong tornadoes tend to be large, ratings are not based on size; they are based on the severity of damage the tornado inflicts.
