Should You Open Or Close Windows During A Tornado -

| Factor | Windows | Windows Closed | | :--- | :--- | :--- | | Pressure Equalization | Minimal benefit; natural leakage already achieves this. | Sufficient; no dangerous differential accumulates. | | Internal Wind Speed | High-speed inflow creates internal vortex, lifting roof. | Zero internal wind from exterior. | | Debris Entry | Direct, unimpeded pathway for lethal missiles. | Blocked; glass may break but slows debris velocity. | | Structural Integrity | Severely compromised; internal pressurization aids collapse. | Maintained; wind flows around the envelope. | | Time Efficiency | Wastes 30–60 seconds hunting for windows. | Allows immediate sheltering. | | Risk of Injury | High (cuts from opening, debris entry, glass blow-back). | Low (broken glass stays mostly near window frame). |

hey that's so cool. i was recently asked about opening your windows before a tornado to equalize the pressure between the outside. YouTube·CBS Pittsburgh should you open or close windows during a tornado
