This document summarizes key information about tornadoes: 1) Tornadoes can cause extensive damage and travel up to 250 miles per hour. They form from thunderstorms and warm, moist air. 2) Tornado season varies by region, with the southern states seeing most tornadoes between March and May, and the northern states during the summer. 3) Tornado strength is measured using the Fujita scale, though this rating occurs after the fact and relies on damage assessments.

• Tornadoes can cause really bad
damage.
• Some tornadoes can travel 250 miles
an hour
• Tornadoes are caused by
thunderstorms develop in warm
moist air
• The picture in the back is a tornado
with lighting around it.

3. Where do they occur??
Tornadoes can happen at any time of the year and at
any time of the day. In the southern states, peak
tornado season is from March through May. Peak
times for tornadoes in the northern states are during
the summer. A few southern states have a second
peak time for tornado outbreaks in the fall.
Tornadoes are most likely to occur between 3 p.m.
and 9 p.m.

4. How to measure tornadoes???
• Since the Fujita Scale is based on
damage and not really wind speed or
pressure, it is not perfect. The primary
problem is that a tornado can only be
measured in the Fujita Scale after it has
occurred. Secondly, the tornado can not
be measured if there is no damage when
the tornado occurs in an area without
any features to be damaged.
Nonetheless, the Fujita Scale has
proven to be a reliable measurement of
the strength of a tornado.

5. How to prepare for a tornado.
• DURING A TORNADO: Go to a basement. If you do not have
a basement, go to an interior room without windows on the
lowest floor such as a bathroom or closet. If you can, get
under a sturdy piece of furniture, like a table. If you live in
a mobile home get out. They offer little protection against
tornadoes. Get out of automobiles. Do not try to outrun a
tornado in your car, leave it immediately. If you’re outside,
go to a ditch or low lying area and lie flat in it. Stay away
from fallen power lines and stay out of damaged areas.
IF YOU’RE AT SCHOOL DURING A TORNADO: Every school
should have a disaster plan and have frequent drills.
Basements offer the best protection. Schools without
basements should use interior rooms and hallways on the
lowest floor away from windows. Crouch down on your
knees and protect your head with your arms.
