A mobile home can overturn very easily even if precautions have been taken to tie down the unit. When a tornado warning is issued, take shelter in a building with a strong foundation. If shelter is not available, lie in ditch or low-lying area a safe distance away from the unit. An approaching cloud of debris can mark the location of a tornado even if a funnel is not visible. Before a tornado hits, the wind may die down and the air may become very still.
Tornadoes generally occur near the trailing edge of a thunderstorm.
It is not uncommon to see clear, sunlit skies behind a tornado. If there is no basement, go to an inner hallway or a smaller inner room without windows such as a bathroom or closet. Get away from the windows. Go to the center of the room. Stay away from corners because they tend to attract debris.
