How do you sense a tornado?

There is no special sense for detecting tornadoes. Aside from keeping and eye on weather advisories, the best way to know a tornado is nearby is to see it. Seeing a tornado is not always possible as the tornado may be shrouded in heavy rain, hidden in the dark of night, or blocked from view by buildings, trees, or hills. Tornadoes also make sound, but it is not a reliable indicator, as simple thunderstorm winds can make a similar roaring sound, and the tornado itself may not be audible until it is dangerously close. The pressure drop in a tornado can cause your ears to pop, but the tornado has to be practically on top of you for this to happen.
