According to the scale, EF0 is the weakest tornado category with gusts up to 85 mph (135 kph) and EF5 is the strongest tornado with wind gusts over 200 mph (320 kph).

What is the weakest type of tornado?

An F0 tornado is the weakest tornado on the retried Fujita Scale. An F0 tornado has wind speeds less than 73 mph (116 km/h). Damage from an F0 tornado is described as light. In the United States, between 1950 and Jan 31st, 2007, there was 21,767 confirmed F0 tornadoes.

What is a weak tornado?

The EF scale defines weak tornadoes as ranging from 65-110 mph on a 3 second gust scale. … These are estimates based on damage. Prior to the EF scale being implemented in 2007, the Fujita Scale for F0s and F1s ranged from 40-112 mph.

What is the lowest speed of a tornado?

The Fujita Scale

Is an F6 tornado possible?

There is no such thing as an F6 tornado, even though Ted Fujita plotted out F6-level winds. The Fujita scale, as used for rating tornados, only goes up to F5. Even if a tornado had F6-level winds, near ground level, which is *very* unlikely, if not impossible, it would only be rated F5.

What are the 5 stages of a tornado?

What are the 5 stages of a tornado?

  • Dust-Whirl Stage. Dust swirling upwards from the ground and grows toward the funnel cloud in the sky.
  • Organizing Stage. Downward extend of funnel and “connection” with dust-whirl on the ground.
  • Mature Stage. Tornado on the ground.
  • Shrinkage Stage.
  • Decaying Stage.

  • Wall clouds or an approaching cloud of debris.
  • Large hail often in the absence of rain.
  • Before a tornado strikes, the wind may die down and the air may become very still.
  • A loud roar similar to a freight train may be heard.

Has there ever been an F12 tornado?

The original Fujita Scale actually goes up to F12. An F12 tornado would have winds of about 740 MPH, the speed of sound. Roughly 3/4 of all tornadoes are EF0 or EF1 tornadoes and have winds that are less than 100 MPH. EF4 and EF5 tornadoes are rare but cause the majority of tornado deaths.
