While there is no place that is 100% safe during a tornado, there are ways to provide some protection.
Know where you can take shelter in a matter of seconds, and practice a family tornado drill at least once a year. When a tornado watch is issued, think about the drill and check to make sure all your safety supplies are handy. If the tornado is visible, far away, and the traffic is light, you may be able to drive out of its path by moving at right angles to the tornado. Tablets, or other purification approach in addition your agriculture, Meals Safety tornado safety tips list and Inspection Service publishes iodine that. There were multiple tornadoes with only short separation, but the survey erroneously classified them as one tornado. A tornado is considered "significant" if it was rated EF2 or greater on the Enhanced F scale, or at least F2 on the old F-scale. It is important to know that those definitions are arbitrary, mainly for parsing out more intense tornadoes in scientific research.
A few hours later, despite the tiny odds of a repeat, the second tornado in five days directly hit the base. Most of the time, this happens either with multiple-vortex tornadoes or very small, intense single-vortex tornadoes.
Hurricanes tend to cause much more overall destruction than tornadoes because of their much larger size, longer duration and their greater variety of ways to damage property. We have some public domain images of typical examples of F0 through F5 tornado damage linked from this FAQ's F-scale page.
Even when strongly gripping the girders (if they exist), people may be blown loose, out from under the bridge and into the open--possibly well up into the tornado itself. Whether or not the tornado hits, parking on traffic lanes is illegal and dangerous to yourself and others. Even if your home is tied down, it is not as safe as an underground shelter or permanent, sturdy building. The National Weather Service issued a tornado warning for Covington and Noxubee counties earlier in the day.


There is a statistical trend (as documented by NSSL's Harold Brooks) toward wide tornadoes having higher damage ratings. But in the event that you are caught in the path of a twister, below are quick tips endorsed by the Storm Prediction Center that could save your life. See more about this firsthand from a tornado that hit Oklahoma in this video The slide show on the left explains why this is the last place you should hide. If you can safely get noticeably lower than the level of the roadway, leave your car and lie in that area, covering your head with your hands.
Worth has compiled a very detailed study of several such violent tornado disaster scenarios in the Metroplex, which could be adapted to other major metro areas as well.
Forget about the old notion of opening windows to equalize pressure; the tornado will blast open the windows for you! If you are caught by extreme winds or flying debris, park the car as quickly and safely as possible -- out of the traffic lanes.
There are many good websites with tornado information, but also, many inaccurate and unreliable ones. That is more unusual than it seems, because most video that seems to show tornadoes merging actually involves either one tornado, or one among multiple subvortices, going behind another. Grazulis (1993) also included killer tornadoes of any damage rating in his significant tornado database. By most measures, SPC (formerly SELS, NSSFC) has improved its tornado forecasting over the past few decades. Otherwise, public-domain tornado damage pictures are scattered among the tornado-related historic news items of various National Weather Service websites. There is no safe option when caught in a tornado in a car, just slightly less-dangerous ones. Most tornadoes can destroy even tied-down mobile homes; and it is best not to play the low odds that yours will make it. This mobile-home safety video from the State of Missouri may be useful in developing your plan. All administrators of schools, shopping centers, nursing homes, hospitals, sports arenas, stadiums, mobile home communities and offices should have a tornado safety plan in place, with easy-to-read signs posted to direct everyone to a safe, close by shelter area.


If you can safely get noticeably lower than the level of the roadway,leave your car and lie in that area, covering your head with your hands. Tornado formation is believed to be dictated mainly by things which happen on the storm scale, in and around the mesocyclone. To oversimplify this a bit, a tornado (or any other atmospheric vortex) is the most efficient way to move air from one part of the atmosphere to another on its size and time scale. There are many ways to objectively gauge forecast performance--for example, verifying tornado watches with tornado reports and both watch types by all severe reports. I am a school administrator, and I don't know where to start with developing a safety plan. Go to one of those shelters, or to a nearby permanent structure, using your tornado evacuation plan. The Enhanced F-scale (simple table or detailed 95-page PDF) is a much more precise and robust way to assess tornado damage than the original. It may sound trite; but by far, the most important software in the tornado forecast process is within the human brain. The general trend from 1985 onward has been for a greater percentage of tornado watches to contain tornadoes, and for more significant (EF2-5) tornadoes to occur in watches and outlooks.
The benefits of this extend into many areas, including: improving building codes for resistance against most tornadoes (since most are weak anyway), the insurance and re-insurance industries, construction designs and practices, and comparisons of tornado damage with their weather situations and radar signatures (for improved watches and warnings). F1 through F5 were used in practice, with F0 attached for tornadoes of winds weaker than hurricane force. Killer tornadoes, those striking densely populated areas, or those generating reports of exceptional damage are given highest priority for ground surveys. Doppler radar signatures can tell warning meteorologists a great deal about a thunderstorm's structure, but usually can't see the tornado itself.
