What is the maximum speed of a F4 tornado? 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.

- Some tornadoes move faster than some cars (record speed for a tornado moving across land is 72.6 mph (116.8 km/h)), even when the road is clear and flat. Any of these situations can leave drivers stranded in the path of the tornado far from substantial shelter.

- The speed classifications are as follows: 1  F-0: winds from 65-85 mph. 2  F-1: winds from 86-110 mph. 3  F-2: winds from 111-135 mph. 4  F-3: winds from 136-165 mph. 5  F-4: winds from 167-200 mph. 6  F-5: winds more than 200 mph.

About Tornadoes Tornado paths range from 100 yards to 2.6 miles wide and are rarely more than 15 miles long. They can last from several seconds to more than an hour, however, most don't exceed 10 minutes. Most tornadoes travel from the southwest to northeast with an average speed of 30 mph, but the speed has been observed to range from almost no motion to 70 mph.

Tornado: Highest Recorded Wind Speed in Tornado (via Doppler Radar) http://www.spc.noaa.gov/faq/tornado/#History Discussion Mobile Doppler radars such as the University of Oklahoma's Doppler on Wheels have remotely sensed tornado wind speeds above ground level as high as about 302 mph. Note that is NOT the fastest measured wind speed since the winds are not directly determined by instrumentation but rather established by computer doppler wind algorithms.

- A tornado is a type of storm in which powerful rotating winds form a column, which reaches from a cloud down toward the ground. The winds of a tornado are the strongest on Earth. They may reach speeds of up to 300 miles (500 kilometers) per hour.

Tornado preparedness Tornadoes are classified by wind speed and damage according to the Fujita Scale. A tornado is a violent rotating column of air extending from a thunderstorm to the ground.The most violent tornadoes can produce massive destsruction with wind speeds of 250 mph or more. Damage paths can be more than 1 mile wide and 50 miles wide. The typical tornado moves from southwest to northeast, but they have been known to move in any direction. The average forward speed of a tornado is 30 mph but it may vary from stationary to 70mph.

What Does Hurricane Category 1, 2, 3 . . . Really Mean? Category 4: Winds range from 131 to 155 mph and can cause catastrophic damage to property, humans, and animals. Severe structural damage to frame homes, apartments, and shopping centers should be expected.

Wind turbine design All wind turbines are designed for a maximum wind speed, called the survival speed, above which they will be damaged. The survival speed of commercial wind turbines is in the range of 40 m/s (144 km/h, 89 MPH) to 72 m/s (259 km/h, 161 MPH). The most common survival speed is 60 m/s (216 km/h, 134 MPH).

Whats the strongest or fastest wind speeds in a tornado ever recorded? The fastest wind measured prior was 286 mph on April 26, 1991 in a tornado near Red Rock, Oklahoma. The 318 mph speed placed the tornado 1 mph below an F6 on the 0 to 6 Fujita scale. No tornado has ever been classified as an F6.

Tornadoes: An Introduction to Nature's Most Violent Storms When a tornado does form, it's strength is measured using a scale known as the Enhanced Fujita (EF) scale. 1  This scale estimates wind speed by taking into consideration the type of structure that was damaged and the degree of damage to it. The scale is as follows: 2  EF0: 65-85 mph winds. 3  EF1: 86-110 mph winds. 4  EF2: 111-135 mph winds.

Thunderstorm Hazards - Tornadoes For example, with the EF Scale, an F3 tornado will have estimated wind speeds between 136 and 165 mph (218 and 266 km/h), whereas with the original F Scale, an F3 tornado has winds estimated between 162-209 mph (254-332 km/h).

- Strong tornadoes have wind speeds reaching about 205 mph, with an average path length of 9 mi, and a path width of 200 yd. Almost 30% of all tornado deaths occur each year from this type of storm. Nearly 70% of all tornado fatalities, however, result from violent tornadoes.

- Doppler radar measures 318 mph wind in tornado. By Jack Williams, USATODAY.com. Scientists measured the fastest wind speed ever recorded, 318 mph, in one of the tornadoes that hit the suburbs of Oklahoma City on May 3, 1999. The record-setting wind occurred about 7 p.m. near Moore, where the tornado killed four people and destroyed about 250 houses.

Speed of the Winds in a Tornado Tornadoes usually lasts only a few minutes, but they are very intense. Their wind speeds range from 18 to 140 m/s. The damage path of a tornado is usually less than 500 meters wide and it travels at less than 16 m/s. Each year, the United States ranks number one in tornado incidence with Australia coming in second. Very often, the most devastating ones occur in Bangladesh.

The Enhanced Fujita Scale: How Tornadoes are Rated Original Fujita Scale estimated wind speeds: 73 to 112 mph. Enhanced Fujita Scale estimated wind speeds: 86 to 110 mph. Typical Observations: Moderate damage. Roofs severely stripped; mobile homes overturned or badly damaged; loss of exterior doors; windows and other glass broken.

- A hurricane with maximum sustained wind speeds exceeding 249 km/h is referred to as Category 5. A wind gust of 318 mph was measured by Doppler radar during a tornado in Moore, Oklahoma, in 1999. However, Doppler records are not considered official.

- Even if the winds measured by portable Doppler radar (32 meters above ground level, roughly 302 mph) had been over 318 mph, the tornado still would have been rated only. F5, since that is the most intense possible damage level. On the Enhanced F-scale, there is no such thing as EF6 or higher.
