- Do not leave your place of safety until the storm passes or you are instructed to do so.
If caught out in the open, on or off campus, and the storm warnings sound, evaluate your situation quickly. Get inside a building if possible, seek a lower floor or inner corridor. Even a metal building will offer some protection. If no buildings are close by, lie flat in the nearest depression, such as a ditch or ravine.
If there is time, move away from the path of the tornado at a right angle. Do not seek shelter under bridges or overpasses. Use extreme caution due to flying debris but do not try to outrun the storm.
