Overpass Tornado
This is a famous video of a tornado which formed April 26, 1991
that passed right over people hidden under bridge. They
tried to escape the line of fire, but eventually couldn't outrun
the tornado.
The Facts on tornadoes:
A tornado is a violently rotating column of air which is in
contact with both a cumulonimbus cloud or, in rare cases, a
cumulus cloud base and the surface of the earth. Tornadoes come
in many sizes but are typically in the form of a visible
condensation funnel, whose narrow end touches the earth and is
often encircled by a cloud of debris.
Most tornadoes have wind speeds of 130 mph (177 km/h) or less,
are approximately 250 feet (75 m) across, and travel a few miles
(several kilometers) before dissipating. Some attain wind speeds
of more than 300 mph (480 km/h), stretch more than a mile (1.6
km) across, and stay on the ground for dozens of miles (more
than 100 km).
