Keep listening to EAS, NOAA Weather Radio, and local authorities for updated information until they give you the all clear to venture outside. Since low pressure systems rotate counterclockwise (and this is due to the Coriolis effect), tornado rotation also tends to be inherited from the low pressure systems. While tornadoes are most common in the Great Plains that doesnt mean they only form on flat land! Decreasing the air pressure in a house by opening a window does nothing to decrease the DAMAGE.
