If a tornado were approaching, the sky would likely darken with ominous clouds, and you may see a rotating, funnel-shaped cloud descending from the storm clouds. The wind would intensify, and you may hear a roaring sound similar to a freight train. It is crucial to seek shelter immediately in a sturdy building or underground.
It is not known for certain, but a likely candidate was the tornado that hit Seneca, Kansas on May 27, 1896. At one point the tornado was 2.2 miles wide. The largest tornado ever recorded was the El Reno, Oklahoma tornado of May 31, 2013, measured at one point to be 2.6 miles wide. This tornado was officially rated EF3 as it was over open country when it reached peak intensity and so caused relatively little damage at that point. Radar analysis, however, suggests that it may have reached EF5 intensity.
Tornadoes often form in open fields because the flat terrain allows warm air from the ground to rise easily. This rising warm air meets with cool air aloft, creating instability that can trigger the rotation needed for a tornado to form. Additionally, open fields have less friction to disrupt the rapidly rotating winds that fuel tornado development.
That is difficult to determine. There have been many thousands of F0 and EF0 tornadoes with winds possibly as low as 40 mph. However it is difficult to determine which were the weakest as many took place in open fields and caused no damage and all but perhaps a few never had their winds measured. Even then, it could be debated whether a tornado with winds as low as 40 mph could actually be counted as a tornado as such winds usually cannot cause significant damage.
Some dust can get blown in through open windows and doors, but even if these are closed, lots of "dust" will be produced by cells being exfoliated from the residents' skins.
You don't. You should actually keep the windows shut to try to prevent wind from entering your home.
No, it is not recommended to open windows in your house if a tornado is approaching. Doing so can allow strong winds to enter the house, increasing the risk of damage and injuries. It is best to take cover in a safe location such as a basement or interior room away from windows.
No, it is not a good idea to open your windows during a tornado. Doing so could increase the likelihood of debris entering your home and causing damage or injury. It is better to seek shelter in a safe, interior room away from windows.
Usually - yes. If you're caught out in the open and a tornado is approaching... the safest place to shelter is underneath the overpass - as high up the sloping bank as possible.
you should open all windows/hatches after fueling your boat
No. Opening windows will only expose the interior of your house to more damage. If there is a tornado in your area take cover immediately! The idea that opening windows to equalize pressure will save you house is a myth. The pressure difference inside a tornado is not enough to cause significant damage. This has been mathematically proven. Tornadoes produce damage though their powerful winds, and in any tornado strong enough to significantly damage a house, the windows will break anyway.

Lie in a ditch or depression in the ground if you cannot get to shelter.
to prepare for a tornado you need to have canned food and water bottles ready because you do not know how much the tornado will last do not open windows or doors have a radio and check for news broadcasts and have faith in yourself and remember tornadoes are dangerous things so be aware
Things not to do in a tornado:Go outside (unless you have to to reach your storm cellar.)Attempt to flee your neighborhood in a vehicle.Seek shelter under a bridge.Take time to open or close windows.
