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.
If no shelter is available lie down in a ditch.
NO!! DO NOT DO THIS!! This was made up by "Professionals" back in "the day" because they didn't understand tornadoes well. Opening windows will take the precious time of trying to get to safety, so do not do this.
You shouldn't. Contrary to popular belief opening windows during a tornado does nothing to save a house and may in fact make damage worse. If a tornado is coming opening windows is a waste of precious time that you should use to take cover.
You don't. You should actually keep the windows shut to try to prevent wind from entering your home.
A sesame comes before the word "open".
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.

Do not even think about opening windows and doors if the tornado is very close. Take shelter where ever possible and do so immediately. No house is worth your life.No. If the center of a tornado ever passed over your house, the wind and debris it was carrying would already have broken at least a few windows before any significant pressure difference could cause problems. It's not likely that this difference is even enough to do much to a well-built home anyway, especially when most houses have enough openings and vents as it is.
Windows are best left closed in a tornado. If you are not hit hard, the windows can prevent interior damage. If you are hit hard by a strong enough tornado some windows will break anyway. But if a tornado is coming it is best not to waste time opening or closing windows. Take cover immediately.
If you do not have a cellar, or basement, stay towards the center of the house, away from any windows, I've had to flip a couch over and use it for shelter before, since I didn't have a basement, and felt the cellar was unsafe. A closet or bathroom often provides good shelter. During a Tornado Warning, I will usually leave the windows cracked open so they don't get blown out by the heavy winds, even though they may get broken due to debris, I will leave the doors shut though.
Before any interior painting
This is based on the old and now disproven idea that the low pressure inside a tornado caused buildings to explode. The idea holds that as a tornado passes over, the pressure outside drops radily, while pressure remains high inside the building, and that opening windows would relieve this pressure difference. This idea has been disproven, and officials now advise against opening windows during a tornado. There are several reasons for this. First, the pressure drop inside a tornado is not large enough to inflict any significant damage on a stroncutre. Second, buildings are not airtight, and pressure will equalize fairly quickly. If a tornado is strong enough to cause significant damage, the windows will likely break anyway Tornadoes cause damage through wind and debris, not through pressure drop. It has actually been shown that if the tornado is weak enough that windows remain intact, or if the worst of the tornado misses, opening windows allows wind to enter the building and cause damage on the inside. Additionally, opening windows wastes precious time that should be spent getting to a safe place.
