AI tells users to 'open windows to equalize pressure' during a tornado, but this outdated advice increases debris entry; modern guidance is to close everything and shelter in an interior room

Root Cause

The AI relies on a debunked myth from the 1970s that opening windows prevents tornado damage, but modern meteorological research shows pressure differentials are not dangerous and open windows allow lethal debris and wind to enter, increasing injury risk.

Workarounds

  1. 95% success Close all windows and doors immediately. Move to a basement, storm cellar, or interior room on the lowest floor (e.g., bathroom, closet, hallway) with no windows. Cover yourself with a mattress or heavy blankets for debris protection.

Dead Ends

Common approaches that don't work:

  1. 95% fail

    Suggesting opening windows on the leeward side only; still allows debris entry and is not recommended by NOAA or FEMA

  2. 90% fail

    Recommending opening windows to 'let the tornado pass through'; this is based on the false premise that tornadoes are pressure-driven, not wind-driven

  3. 85% fail

    Advising to open windows only if you have time; any open window increases risk of projectile injury, and time is better spent sheltering
