It's
Tornado
Season
Tornadoes are nature’s most violent storms. Spawned
from powerful thunderstorms,
tornadoes can cause fatalities and
devastate a neighborhood in seconds.
A tornado appears as a rotating,
funnel-shaped cloud that extends
from a thunderstorm to the ground
with whirling winds that can reach
300 miles per hour. Damage paths can
be in excess of one mile wide and 50
miles long. Every state is at some
risk from this hazard.
Some tornadoes are clearly visible, while rain or
nearby low-hanging clouds obscure
others. Occasionally, tornadoes
develop so rapidly that little, if
any, advance warning is possible.
Before a tornado hits, the wind may die down and
the air may become very still. A
cloud of debris can mark the
location of a tornado even if a
funnel is not visible. Tornadoes
generally occur near the trailing
edge of a thunderstorm. It is not
uncommon to see clear, sunlit skies
behind a tornado.
The following are facts about tornadoes:
-
They may strike quickly, with
little or no warning.
-
They may appear nearly
transparent until dust and
debris are picked up or a cloud
forms in the funnel.
-
The average tornado moves
Southwest to Northeast, but
tornadoes have been known to
move in any direction.
-
The average forward speed of a
tornado is 30 MPH, but may vary
from stationary to 70 MPH.
-
Tornadoes can accompany tropical
storms and hurricanes as they
move onto land.
-
Waterspouts are tornadoes that
form over water.
-
Tornadoes are most frequently
reported east of the Rocky
Mountains during spring and
summer months.
-
Peak tornado season in the
southern states is March through
May; in the northern states, it
is late spring through early
summer.
-
Tornadoes are most likely to
occur between 3 p.m. and 9 p.m.,
but can occur at any time.
What to do Before a Tornado
Be alert to changing weather conditions.
-
Listen to
NOAA
Weather Radio or to
commercial radio or television
newscasts for the latest
information.
-
Look for approaching storms
-
Look for the following danger
signs:
-
Dark, often greenish sky
-
Large hail
-
A large, dark, low-lying cloud (particularly
if rotating)
-
Loud roar, similar to a freight train.
If you see approaching storms or any of the danger
signs, be prepared to take shelter
immediately.
What to Do During a Tornado
If you are under a tornado WARNING, seek shelter
immediately!
|
If you are in:
|
Then:
|
|
A structure (e.g.
residence, small building,
school, nursing home,
hospital, factory, shopping
center, high-rise building)
|
Go to a pre-designated
shelter area such as a safe
room, basement, storm
cellar, or the lowest
building level. If there is
no basement, go to the
center of an interior room
on the lowest level (closet,
interior hallway) away from
corners, windows, doors, and
outside walls. Put as many
walls as possible between
you and the outside. Get
under a sturdy table and use
your arms to protect your
head and neck. Do not open
windows.
|
|
A vehicle, trailer, or
mobile home
|
Get out immediately and
go to the lowest floor of a
sturdy, nearby building or a
storm shelter. Mobile homes,
even if tied down, offer
little protection from
tornadoes.
|
|
The outside with no
shelter
|
Lie flat in a nearby
ditch or depression and
cover your head with your
hands. Be aware of the
potential for flooding.
Do not get under an overpass
or bridge. You are safer in
a low, flat location.
Never try to outrun a
tornado in urban or
congested areas in a car or
truck. Instead, leave the
vehicle immediately for safe
shelter.
Watch out for flying debris.
Flying debris from tornadoes
causes most fatalities and
injuries

Recovering from Disaster
Recovering from a disaster is usually a gradual
process. Safety is a primary issue,
as are mental and physical
well-being. If assistance is
available, knowing how to access it
makes the process faster and less
stressful. This section offers some
general advice on steps to take
after disaster strikes in order to
begin getting your home, your
community, and your life
