Originally winds in an F4 tornado were estimated to be 207-260 mph, but this was found to be far too high and revised to 166-200 mph for an EF4 tornado. A tornado of this strength can completely level well-built houses, peel asphalt from roads, and turn large objects into high-speed projectiles.
The infamous 1979 Wichita Falls tornado was an F4.
An F4 tornado can be devastating. An F4 tornado will level well-built houses and strip bark from trees. Such tornadoes have been known to wipe out large sections of cities and towns. While most of the worst tornadoes in U.S. history have been F5s, several F4 tornadoes are on that list as well.
An F4 tornado is classified as an intense tornado with wind speeds between 207-260 mph. The damage it can cause is devastating, often leveling well-constructed houses and sending cars flying through the air. The path of destruction can be several miles long and a mile wide.
Violent tornadoes of F4 or F5 strength can remove houses from their foundations. Less intense tornadoes may move houses that are not properly anchored.
A VERY Powerful Tornado that causes Devastating damage. Well-constructed houses leveled; structures with weak foundations blown away some distance; cars thrown and large missiles generated. It is the second strongest category on the Fujita scale, which goes from F0 to F5.
The Hallam, Nebraska tornado was rated F4
Yes. North Carolina has had tornadoes as strong as F4.
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.
The Goliad, Texas tornado was an F4.
An F4 or higher tornado (the only higher rating being F5) is classified as violent.
The F4 tornado that hit Hamden, Connecticut in 1989 struck on July 10.
Yes. Tornadoes have been known to lift houses into the air. It usually takes a very strong tornado to do so, generally of F4 or F5 intensity.
Yes. F4 is the second strongest category on the Fujita scale, indicating an extremely powerful tornado that can completely level well-built homes.
An F4 tornado moved along the northern part of the San Antonio area on April 28, 1953, killing one person.
There have been a number of tornadoes that have stuck St. Louis including a few F4 tornadoes. The most significant tornado to strike the city, which occurred on May 27, 1896 and killed 255 was an F4.
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.
An F4 tornado can be a quarter of a mile wide, but that is by no means a requirement. Tornado ratings are based on the severity of the damage, not the size of the tornado. There is a tendency for violent tornadoes to be large, but they don't have to be. A path width of 1/4 mile would not be uncommon for an F4, but sizes have ranged from as small as 100 yards to as wide as 2.5 miles.
