The Federal Alliance for Safe Homes (FLASH) is a nonprofit organisation that advocates for safeguarding people and property from weather disasters. They have published a tornado weather protection fact sheet that aims to advise people how best to protect themselves before, during, and after a tornado strike.

The differences between a tornado watch and a tornado warning

  • A tornado watch is declared when conditions exist which are likely to result in a tornado forming. These can cover areas as small as cities to multiple states.
  • A tornado warning is issued when a tornado has been sighted or indicated by weather radar. A warning means that it is time to take action because there is imminent danger to life and property.

What to do if you’re under a tornado warning

If you are under tornado warning, there are a number of actions that can be taken to keep you and your loved ones safe. This includes taking shelter in an ICC 500 certified tornado shelter or a safe room as well as not opening windows. Other advice includes taking cover in a windowless room as well as lying under something protective, such as a mattress.

Not everyone will be indoors when a tornado strikes. If you are unable to get inside then seek shelter in a low-lying area such as a ditch or ravine, abandoning your vehicle.
