No. In fact the vast majority of tornadoes in the northern hemisphere (more than 99%) spin counterclockwise.
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.
No. It is not uncommon for conditions to become unusually calm before a tornado strikes.
No. A tornado is a violently rotating column of air extending from the base of a thunderstorm to the ground. A tornado is often, but not always made visible by a funnel cloud. But the tornado is not the cloud itself.
An isolated tornado in Texas is little different from an isolated tornado anywhere else. An isolated tornado occurs with few or no other tornadoes in the region. Such tornadoes are usually, but not always, weak but are still dangerous. Like any other tornado, an isolated tornado will damage or destroyed trees and man-made structures in its path.
No. Depending on the way the light hits the tornado and the color of the dust a it may pick up a tornado can also be black, white, brown or red.
In the northern hemisphere, yes, with the exception of the rare anticyclonic tornado But in the southern hemisphere tornadoes almost always rotate clockwise.
Tornadoes nearly always spin counterclockwise if they are in the northern hemisphere and clockwise if they are in the southern hemisphere.
No. Tornadoes almost always rotate clockwise in the southern hemisphere. Counterclockwise tornadoes are in the northern hemisphere.
Tornadoes nearly always spin counterclockwise in the northern hemisphere and clockwise in the southern hemisphere with the exception of about 1% which are called anticyclonic tornadoes.
You should always always pass your food counter-clockwise. That is to say, pass to your right.
Always clockwise.

Yes. Twister is just an informal word for tornado.
A tornado does not always have an eye. When it does it can be about a quarter of the width of the funnel.
clockwise always
No, it can not happen. You will always need a cloud to form a tornado. The kind of cloud that a tornado uses is a cumulonimbus cloud.
Tornadoes are often but not always accompanied by hail. However, the hail is not a result of the tornado itself but the storm that produces the tornado.
