2. What is a Tornado?
A tornado is a mobile, destructive vortex of violently rotating winds having the appearance of a funnel-
shaped cloud and advancing beneath a large storm system.
3. How dangerous is a Tornado?
Wind speeds in tornadoes can exceed 200 mph.
An overpass may be one of the worst places to seek shelter from a tornado.
An overpass as tornado shelter can put people at a greater risk of being killed or seriously injured by flying debris from the
powerful tornado winds.
4. Most dangerous Tornado.

Weather Service in Norman, Oklahoma announced on Tuesday.

6. How are Tornados made?
Tornadoes are usually the extreme result of a very large thunderstorm called a supercell.
During the storm cold air and warm air combine.
The cold air goes drops as the warm air rises.
The warm air eventually twists into a spiral and forms a funnel cloud.
7. What are the scales of a Tornado?
The scales tell you how big the Tornados are and how dangerous they are.

9. Facts about Tornados.
A tornado is as a rotating, funnel-shaped cloud that extends from a thunderstorm to the ground with whirling
winds that can reach 300 mph.
Damage paths of tornadoes can be in excess of one mile wide and 50 miles long.
Tornadoes can accompany tropical storms and hurricanes once on land. Its super important to be prepared
for a tornado, so make sure you have a disaster plan for your pets too!
Rotating thunderstorms are the best predictors of tornado activity.They are well defined thunderstorms on
radar that may include hail, severe winds, lightning, or flash floods.
Tornadoes can occur when a warm front meets a cold front, forming a thunderstorm, which then can spawn 1
or more “twisters."
