Severe Storms
 Activating
Strategy: Share with your
neighbor a story you have about
experiencing a severe storm.
Storm
A
storm is a
violent
disturbance in
the atmosphere.
Thunderstorms

Thunderstorms are
heavy rainstorms with
thunder and lightning
 Warm, humid air rises
rapidly and form
cumulonimbus clouds
 1. Energy
 2. Updrafts (a pocket
of rising warm air)
 3. Downdrafts (sinking
cool air)
 Lightning
= spark
caused when electrical
charges jump between
parts of a cloud or
between the cloud and
the ground.
 Thunder
= the sound
of air expanding
suddenly and
explosively.
Hail

Hail: Balls of ice
formed in a
thunderstorm.

Safety: get out of your
car and get inside of a
building. Stay away
from windows.
Hail Formation
 hail
formation
Thunderstorm safety
 Do
not touch metal objects
 Find a low area away from fences, trees
and poles
 Crouch down with your head down and
your hands on your knees.
 Stay away from water
 Do not touch telephones, appliances, or
faucets.
 Staying in a car is ok if you don’t touch any
metal in the car.
Tornadoes
Tornadoes have the most powerful winds
on earth!
Tornados

Tornado = a fast
turning, funnel-shaped
cloud that reaches
down from a
cumulonimbus cloud to
touch the Earth.

A tornado watch :
Tornados are possible
in your area

A tornado warning :
A tornado has been
seen.
Tornados
Tornado Safety
 Go
to a basement of a strong building or
the middle of the ground floor.
 Stay away from windows and doors.
 Lie under a strong piece of furniture.
 If you are outdoors in a car or mobile
home, move to a building or lie flat in a
ditch.
Hurricanes

Hurricanes form over
warm ocean water near
the equator. The warm,
moist air evaporates and
condenses and forms
clouds in circular bands.
A tropical cyclone forms
so many cumulonimbus
clouds that they arrange
in circular bands
Hurricanes

The storm surge is
the most dangerous
threat to life and
property. Low air
pressure causes the
water to rise and pile
up.

Hurricanes

A hurricane is a tropical storm
that has winds of 119
kilometers per hour or higher.

A hurricane watch :A
hurricane is possible in the


A hurricane warning :A

Winter storms

Heavy snow falls can
block roads, trapping
people in their homes
and can cause pipes
to burst.
Winter Storm Safety
 If
you are caught in a snow storm, try to
find shelter from the wind.
 Cover the exposed parts of your body and
stay dry.
 You can stay in a running car only if the
exhaust pipe is free of snow.
Winter Storm Safety

Frostbite happens when parts of the body
freeze. Symptoms: loss of feeling and a white
look to the area. If you think you have frostbite,
slowly re-warm the area and get help.

Hypothermia is when body temperature falls
below normal. Symptoms: shivering,
disorientation, slurred speech, and sleepiness. If
someone shows symptoms of hypothermia, get
them to a doctor right away.
Drought

A drought is a water
shortage caused by
long periods of low
precipitation in a
particular area.

Drought can cause
entire crops to fail.
This leads to higher
food prices.
Sandstorms

Sandstorms can be
formed when small,
light dust is blown in
to the air lifted by
strong winds.

Safety; Tie down
anything that is
loose and get
indoors.
