Tornadoes are not very common in portugal, but in USA for example, they occur very often, here are some safety tips concerning tornadoes:

-Before it occurs make sure everyone knows where to go in case a tornado threatens, prepare a disaster supplies kit for your home and car than includes a first aid kit, canned food and a can opener, bottled water, battery-operated radio, flashlight, protective clothing and written instructions on how to turn off electricity, gas, and water.

-During the tornado is very important to be in a place without windows so go to the basement, if you don't have a basement go to an interior room without windows on the lowest floor such as a bathroom or closet. Stay away from fallen power lines and stay out of damaged areas.

-After a tornado stay indoors until it is safe to come out. Check for injured or trapped people, without putting yourself in danger.
