There is no real set lower limit for the wind speed of a tornado. The Fujita scale starts wind speed estimates for an EF0 tornado at 65 mph, but some tornadoes have had estimated winds as low as 55 mph. On the original Fujita scale, F0 wind estimates start at 40 mph. Actual wind measurements from tornadoes are rare, so winds are usually estimated from damage. Many tornadoes, expecially some short-lived, weak ones, stay in open fields and never cause damage, making it impossible to estimate wind speed.
The Enhanced Fujita Scale places minimum wind estimates for an EF0 tornado at 65 mph but estimates for damage potential range as low as 45 mph for some damage indicators.
However, tornadoes are not classified base on direct wind estimates and it is rare to obtain such a measurement from a tornado.
Usually it is enough for there to be a visible dust/debris whirl under a funnel cloud to confirm that a tornado is on the ground.
the highest speed of wind recorded for a tornado is 302 mph.
Very few wind measurements are taken from inside of tornadoes, so wind speeds are usually esitmated. Estimates on some weak tornadoes have been as low as 55 mph.
267 Km per hour or 166 miles per hour. Though this is just an estimate that corresponds wit EF4 damage.
The fastest wind ever recorded in a tornado was 302 mph +/- 20. Note: actual wind measurements in tornadoes are rare. The majority of tornadoes have their winds estimated from damage.
301 mph +/- 20.
There is no single slowest tornado as many tornadoes have been completely stationary and just stayed on one spot.
the slowest animal only moves 10 Centimetres per minute
In most cases the wind speed of a tornado is estimated based on the severity of the damage it causes.
An EF5 tornado has winds in excess of 200 mph.
Tornado intensity is determined by damage, which is used to estimate wind speed. These wind speed estimates are used to sort a tornado into one of six categories from EF0 to EF5.
There is no single slowest tornado as many tornadoes have been completely stationary and just stayed on one spot.
The slowest speed an object can move is zero.
the Elmatross is the slowest
The slowest I've ever seen was 5 MPH, but this was on private property.
FASTEST when dealing with speed
the slowest animal only moves 10 Centimetres per minute
Monkeys
the slowest land mammal is the three-toed sloth and it can go up to 1.2 mph
The wind speed of a tornado is inferred from the severity of the damage it inflicts.
