Answer:
Tornado is a phenomenon that happens unexpectedly, but tornado most often happens in spring.
Explanation:
This time when the weather is changing is the peak of tornados. As the spring is in the middle of the winter and the summer, cold and warm air are mixing and storms are more likely to happen.
Also, the timing for the tornado is afternoon, as the air is the hottest at that time. Tornado is often deadly because it can be mixed with a storm and strong wind.
