Step-by-step explanation:
The peak tornado season in the USA is generally during the spring months of March, April, and May. During this time, the conditions in the central United States, particularly in the region known as tornado alley, are most favorable for the formation of tornadoes.
Tornadoes are formed when warm, moist air from the Gulf of Mexico meets cold, dry air from the Rocky Mountains and clashes with each other. This collision creates powerful thunderstorms that can produce tornadoes.
It is important to note that tornadoes can occur in other parts of the country and at other times of the year as well, but the peak season for tornado activity is typically in the spring.
