Where do tornadoes usually occur?
In the U.S. they are most common in the central plains of North America, east of the Rocky Mountains and west of the Appalachian Mountains. They occur mostly during the spring and summer; the tornado season comes early in the south and later in the north because spring comes later in the year as one moves northward.
How do you tell if a storm will produce a tornado?
There are several atmospheric warning signs that precipitate a tornado’s arrival:
- A dark, often greenish, sky.

How do tornadoes stop?
Tornadoes are able to die off when they move over colder ground or when the cumulonimbus clouds above them start to break up.
