Assuming that Earth is an inertial frame, and that the refraction index of air=1, the maximum possible velocity on Earth is the speed of the light, which equals 299 792 458 m/s. Albert Einstein postulated this back in early 1900's.

It is not possible to prevent a tornado from forming. Tornadoes are natural weather phenomena that occur as a result of specific atmospheric conditions. However, scientists and meteorologists continuously work on improving tornado warning systems and forecasting techniques to help mitigate the potential impact and provide early warnings to communities in the affected areas.

No most tornado strikes happen in the Midwest in tornado valley but they can happen any where but mainly in middle March to early October
Tornadoes are very difficult to predict. The possibility of tornadoes occurring can be predicted hours ahead of time based on general weather conditions . In this case a tornado watch is issued. But within a large area there is no way of known with any certainty where or when a tornado will strike or if one will occur at all. If a tornado is occurring or a storm may soon produce a tornado, a tornado warning is issued for an area about the size of a county. Even then, meteorologists cannot be certain where or when a possible tornado will strike.
