Areas near rivers, lakes, mountains, and even cities are safe from tornadoes
.^ No place is safe from
tornadoes. They can cross rivers, travel up mountains, roarthrough valleys and hit major metropolitan areas. The greatTri-State tornado of 1925, the deadliest tornado everrecorded, crossed both the Mississippi and Wabash Rivers. MYTH:
Open windows in your house to equalize pressure. Do not do this! Your house will not "explode" due to atornado passing over it, and taking time to open windowsreduces your ability to seek safe shelter in time. Plus,opening windows allows damaging winds to enter thestructure. MYTH:
Get to (or away from) the southwest corner of the building for safety.
The safest place in a building is in a
small, reinforced room (bathroom or closet) near the centerof the building, on the lowest floor (preferably belowground). Safer yet, of course, is a shelter specificallydesigned for tornado safety. MYTH:
Mobile homes attract tornadoes.
This myth
probably came from the tendency of tornadoes to demolishmobile homes while leaving nearby structures only slightlydamaged. Mobile homes can be severely damaged even byweak tornadoes. If the mobile home is not tied down, it iseven vulnerable to 50 mph winds. MYTH:
Low pressure with a tornado causes buildings to "explode" as the tornado passes overhead.
Violent winds
and debris slamming into buildings cause most structuraldamage. MYTH:
If you are caught out in the open, you should seek shelter under highway overpasses.
Seeking shelter under an
overpass puts you at greater risk of being killed or seriouslyinjured by flying debris from the powerful tornadic winds.Airborne debris is blown into and channeled under theoverpass. Debris of varying sizes and types moving atincredible speeds can easily penetrate clothing and skincausing serious injuries and possibly death. A person couldbe blown out or carried away from the overpass by the fiercetornado winds. People positioned at the top of the overpassencounter even higher wind speeds and more missile-likedebris.
