Tornadoes do not usually travel in a straight line. They can change direction and speed rapidly, making them unpredictable and dangerous. Tornado paths are often characterized by erratic and twisting movements as they move across the landscape.
Tornado Alley.
It varies. The average tornado lasts about 10 minutes and travels about 5 miles. The average forward speed is 35 mph. However some tornadoes last only a few seconds, traveling only a few hundred yards, or sometimes just a few feet. Sometimes a tornado is nearly stationary. In extreme cases a tornado can last for over three hours and travel at over 70 mph. One tornado had a damage path 219 miles long.
If they are willing to pay for the travel then it will occur, this is standard across the country.
