Tornado Alley


While tornadoes can form anywhere in the world, they most commonly form in the Great Plains states of the US, more commonly referred to as "Tornado Alley."

These states are ideal for tornadoes because they tend to be very flat and dry (not many lakes/rivers), which allows cool, dry winds from the north and warm, moist winds from the south to meet and form tornadoes.
