When forecasters see those conditions, they can predict that tornadoes are likely to occur. However, it is not yet possible to predict in advance exactly when and where they will develop, how strong they will be, or precisely what path they will follow. Once a tornado is formed and has been detected, warnings can be issued based on the path of the storm producing the tornado, but even these cannot be perfectly precise about who will or will not be struck. A storm shelter is your best choice, if you have one. If you have no basement or storm shelter, go to an interior room without windows on the first floor of your home.
Bathrooms are a good choice because the plumbing reinforces the walls.
Closets are also a good choice since they normally have no windows. It used to be thought that opening windows would reduce a tornado's damage to a home. If you are traveling in a rural area, drive away from the tornado at a right angle to its path. If you are at school or work, your school or workplace should have an approved tornado safety plan, which you should follow. Knowing what to do in a specific situation means you are less likely to panic and do something dangerous without realizing it.
