Tornadoes



What are tornadoes?

Tornadoes are similar to hurricanes, given that they are also violent, whirling gusts of air that rotate while hitting the ground. They are usually accompanied by heavy rainfall, hailstone, thunders and lightning. Tornadoes develop rapidly and move at high speeds.


How are tornadoes classified?

According to the Fujita Scale, tornadoes are classified into F0-F1-F2-F3-F4-F5. Wind intensity is given in both MPH and KM/H,
as follows:

F0: 40-72mph.............…......65-115km/h
F1: 73-112mph...................117-180km/h
F2: 113-157mph................182-252km/h
F3: 158-206mph................254-332km/h
F4: 207-260mph................334-413km/h
F5: 261-318mph................415-505km/h


What should we do when a tornado happens?

Seek shelter in basements.
Stay away from windows.
Keep open the windows facing the opposite direction of the wind.
If you are outdoors in the country, go to the nearest irrigation channel, trench or hollow and remain there until danger is over.
Do not stay in the car.
