To add from tornado alley, tornados are short lived, usually minutes in any
area to a few hours for a storm spawning them.  While they can be small,
they can also be quite large with a large tornado having a central
path a half mile across with smaller tornados rotating around the larger one
increasing the swath to a mile or more.  The path of a single tornado can be
as short as a few hundred feet to many miles, and they are attracted to
trailer parks.

I have worked disaster response on several large tornados in my area and
have witnessed a couple.  I respect them way more than a hurricane which
gives you lots of warning they are coming.  Tornados can come right out of
the green (the sky often turns a really eery shade of green right before a
tornado is coming).
