It varies widely. A typical tornado travels at between 30 and 40 mph, but some tornadoes are stationary, while others can travel at over 70 mph.
Get under ground as fast as you can.
The Tornado's max speed is 1,490 mph
600 mph
average of 30mph and can reach over 70mph
This is variable and unpredictable, sometimes they will stand stationary on a single spot for a long time then suddenly move away at high velocity.
When surface winds slow down in a tornado due to ground friction, the tornado may weaken or dissipate altogether. This is because a tornado's strength is dependent on the fast rotation of air at the surface, so when this rotation slows down, the tornado's intensity is reduced.
A tornado that does not touch the ground is a funnel cloud.
The average tornado travels at 35 mph. Some tornadoes are stationary or nearly stationary. One tornado in 1925 was determined to have traveled at 73 mph at one point.
How fast a tornado is moving refers to how fast the tornado itself travels from point A to point B. For example, a tornado moving towards at 30 mph and is a mile away will reach you in 2 minutes. The rotational winds of a tornado refers to how fast the tornado itself is spinning, which is generally faster than its forward speed.
A funnel cloud that touches the ground is commonly known as a tornado.
A tornado that doesn't touch the ground isn't a tornado; it is a funnel cloud. However if the funnel is pulling debris off the ground or making some other type of contact with the ground it is a tornado.
