No, some tornadoes will form without a wall cloud. In most cases there are of a variety called landspouts, which are tornadoes that do not form in association with the mesocyclone of a supercell. These tornadoes are typically weak, though on occasion have been known to cause damage as high as F3.

What is the difference of a wall cloud and a water spout?

A wall cloud is part of the mesocyclone of a supercell and is sometimes a precursor to a tornado. A waterspout is basically a tornado on water.


How much damage does the wall cloud do?

The wall cloud itself doesn't do the damage. The wall cloud is an indicator of rotation in a thunderstorm that can lead to the formation of a tornado.


Before the storm turns into a tornado what type of cloud does it form?

Before a storm develops into a tornado, it typically forms a rotating wall cloud. This wall cloud can often be seen beneath a thunderstorm and is a key indicator of a possible tornado forming. It is important to monitor the situation closely and take appropriate precautions if a wall cloud is observed.


What type of cloud rotates at the bottom of a thunderstorm and is a warning sign of a possible tornado?

What is a wall cloud on a tornado?

A wall cloud is a lowering of a cloud base that is often seen before a tornado forms. It marks the most intense portion of the mesocyclone, the rotating updraft from which a tornado forms. The links below shows picture of what wall clouds often look like.


Sighns of a tornado?

A wall cloud is suspended from a cumulonimbus cloud (mostly during thunderstorms). Then the wall cloud begins rotating counter-clockwise. Then a funnel cloud will drop from it.
