On the original Fujita scale the upper limit of F4 wind speed estimates was 260 mph (418 km/h). Later analysis suggested that this was too high an estimated for the upper limit of F4 damage and was revised to 200 mph (322 km/h) for an EF4 tornado.

What is the maximum wind speed of a f4?

A F4 tornado has a maximum speed of 260mph (418 kph). However it should be noted that the wind estimates of the original Fujita scale, which were meant to correlate with damage levels, have been found to be inaccurate. on the new Enhance Fujita scale the top estimated wind speed for an EF4 tornado is 200 mph.


What was the wind speed of the Wichita falls tornado in 1979?

No wind measurements were taken from the Wichita Falls tornado, so the actual wind speed is not known. The tornado was rated F4 based on the severity of the damage it caused, which suggests peak wind speeds in the range of 207-260 mph. However, recent evidence suggests that the original Fujita scale used to rate this tornado may overestimate the wind speeds needed to inflict F3 and higher damage, so winds may not have been quite so fast.


How fast is an f4 tornado?

The estimated wind range for an F4 tornado is 207-260 mph. On the Enhanced Fujita scale this was change to 166-200 mph for an EF4 tornado.


What is the intensity phrase and wind speed of an F4 tornado on the Fujita Pearson Scale?

Damage from an F4 tornado is described as devastating. Originally winds were estimated at 207-260 mph, but this was found to be far too high for the damage inflicted and was adjusted to 166-200 mph on the Enhanced Fujita scale.


How strong is an F4 tornado?

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.


What was the wind speed of the tornado that hit Delhi Louisiana in 1971?

There is no way of knowing for certain as the means of measuring tornado wind speeds had not been invented yet in 1971. Based on damage the tornado was rated F5, which would put estimated winds in the range of 261-318 mph.

How bad is an F4 tornado?

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.
