No, most tornadoes in the Southern Hemisphere rotate clockwise.
Additionally, some tornadoes, called anticyclonic tornadoes, rotate clockwise in the northern hemisphere. Fewer than 1% of tornadoes are anticyclonic.
Tornadoes in the northern hemisphere usually rotate counterclockwise, while tornadoes in the southern hemisphere typically rotate clockwise. This is due to the Earth's rotation and the Coriolis effect.
Tornadoes normally rotate cyclonically in direction: - counterclockwise in the northern hemisphere - clockwise in the southern hemisphere But while large-scale storms always rotate cyclonically due to the Coriolis effect, thunderstorms and tornadoes are so small that the direct influence of the Coriolis effect is inconsequential. Supercells and tornadoes rotate cyclonically in numerical simulations even when the Coriolis effect is neglected. Low-level mesocyclones and tornadoes owe their rotation to complex processes within the supercell and ambient environment. Approximately 1% of tornadoes rotate in an anticyclonic direction. Typically, only landspouts and gustnadoes rotate anticyclonically, and usually only those which form on the anticyclonic shear side of the descending rear flank downdraft in a cyclonic supercell. However, on rare occasions, anticyclonic tornadoes form in association with the mesoanticyclone of an anticyclonic supercell, in the same manner as the typical cyclonic tornado, or as a "companion tornado," either as a satellite tornado or associated with anticyclonic eddies within a supercell.
Fort the most part that is limited to tornadoes in the northern hemisphere. Nearly all southern hemisphere tornadoes rotate clockwise. Tornadoes are formed from thunderstorms called supercells, and get their counterclockwise rotation from the rotation in those storms. The storms get their rotation from wind shear, or differences in wind speed and direction with altitude. In the northern hemisphere the wind shear is usually counterclockwise with increasing altitude. For example the wind at ground level may be out of the west while higher up it is out of the south, so it shifts in a counterclockwise manner. This can impart a counterclockwise spin on the updraft, or rising air current of a thunderstorm.
No. While most tornadoes rotate in a direction that matches earth's (clockwise in the northern hemisphere and counterclockwise in the southern), a small percentage go against this. The origin of the spin in tornadoes is not directly related to earth's rotation. Most tornadoes also move in an easterly direction, but not always.
Tornadoes typically move in the direction of the prevailing winds, but they can also change direction due to the local terrain. Tornadoes can move downhill if the conditions are right, but it is not common.
counter clockwise
Most tornadoes north of the equator go counter clockwise. There are a few that will rotate clockwise. These are referred to as anti-cyclonic. They are still destructive. Two well documented clockwise tornadoes occurred in Grand Island, Nebraska in June of 1980. The famous 'Night of the Twisters' book was based on this event which spawned nine tornadoes, one which moved so slowly through a residential neighborhood that a brisk walk would have outrun it. Four died and 150 blocks were devastated.

they go both ways. More than 99% of tornadoes spin counterclockwise in the northern hemisphere and clockwise in the southern hemisphere. For less than 1% of tornadoes the opposite is true. These are called anticyclonic tornadoes.
