A tornado is most likely to happen in the United States in a section called "Tornado Alley". This includes Oklahoma, Texas, Kansas, Nebraska, North and South Dakota, Florida, Missouri, and more. A tornado is likely to form between 3 pm. and 9 pm.

A watch simply means that conditions are favorable for tornadoes, but does not mean that there is an imminent threat. So a tornado is more likely to strike when a warning is issued.
