Introduction Of Tornadoes:

Tornadoes are nature’s most violent storms. Spawned from powerful thunderstorms. 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.  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.

Cause Of Tornadoes:

• When the ground grows warmer in spring and aloft is cold warm air near the surface rises.As it cools the water vapor it carries condenses forming clouds and thunderstorms.

• Wind near the surface blow in one direction while winds aloft blow in another.

• Rising warm air creates an updraft pulling the rotating air upright.Now the thunderstorm forms a rotating vortex on mesocyclone but only a few mesocyclones spawn tornadoes.Mesocyclone can be five miles across.

Safety Precautions  During a Tornadoes :

• Go to a pre-designated shelter area such as a safe  room  or the lowest building level. 

• If there is no basement, go to the center of an interior room on the lowest level  away from corners, windows, doors, and outside walls.

• Do not open windows.

•  If you are in vehicle immediately get into a vehicle, buckle your seat belt and try to drive to the closest sturdy shelter.

• Put your head down below the windows cover your head with your hands and a blanket, coat or other cushion if possible.

• If you can safely get noticeably lower than the level of the roadway, leave your car and lie in that area, covering your head with your hands.

• 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.

Safety Precautions After Tornadoes:

• Continue to monitor your battery-powered radio or television for emergency information.

• Be careful when entering any structure that has been damaged.

• Wear sturdy shoes or boots, long sleeves and gloves when handling or walking on or near debris.

• Be aware of hazards from exposed nails and broken glass.

• Do not touch downed power lines or objects in contact with downed lines. Report electrical hazards to the police and the utility company.

• Seek prompt medical attention if you suspect CO poisoning and are feeling dizzy, light-headed or nauseated.

• Hang up displaced telephone receivers that may have been knocked off by the tornado but stay off the telephone except to report an emergency.

• Cooperate fully with public safety officials.

• Respond to requests for volunteer assistance by police, fire fighters, emergency management and relief organizations, but do not go into damaged areas unless assistance has been requested. Your presence could hamper relief efforts and you could endanger yourself.
