How do you know when a tornado is finish?

Answer 1

* Wind is invisible. You may not see a tornado until the dust, debris, or clouds get sucked into the funnel. * Most tornadoes travel toward the Northeast, but tornadoes can move in any direction. * Tornadoes usually travel at 30 MPH, but may go as fast as 70 MPH. * Tornadoes can form as tropical storms and hurricanes move onto land. * Waterspouts are just tornadoes that form over water. * Most tornadoes happen east of the Rocky Mountains during spring and summer. * Tornadoes occur most often in the early evening, but can happen any time. * Flying debris causes the most tornado injuries and deaths. * In a permanent structure (not a mobile home): Go to the lowest level (cellars are best) in the center of the building. Put as many walls between you and the outside as possible. Stay away from windows and leave them closed. Get under a sturdy table, face down, with your hands covering your head. * In a vehicle, trailer or mobile home: Get out! Go to the lowest level of a permanent building or storm shelter. If no permanent building is available, follow the tips below for being in the open. If the tornado is far away, you may be able to avoid it by driving in right angles away from the funnel. Never try to outrun a tornado in congested or urban areas; it's safer to get out and seek shelter or a low, flat area. * Out in the open: Lie flat in a depression or ditch, face down with your hands covering your head. Beware of possible flooding. Do not seek shelter under a bridge or overpass; you're safer in a low and flat location. Beware of debris. FEMA suggests looking for the following danger signs: * Dark, often greenish sky * Large hail * A large, dark, low-lying cloud (particularly if rotating) * Loud roar, similar to a freight train. (If you don't hear it anymore or see any of these signs... it's gone...);

You can also go by time; Tornadoes usually last just a few minutes. The shortest last for only a few seconds, but the longest (and most dangerous) can last for over an hour (but these are extremely rare)! Be Safe.
