3. The Sudden Wind Shift
Advertisement
One important clue that a tornado is developing or coming is a rapid and dramatic change in wind direction or speed. Often one of the most obvious and quick indicators that conditions are ready for tornado formation is this wind change. You might go through a period of relative quiet in the run-up to a tornado then see a sharp spike in wind speed. The wind can also veer suddenly, occasionally whirling across 360 degrees in a brief arc. Tornadoes are simply rotating columns of air, hence as they develop or approach they disturb the usual wind patterns in the surrounding area. As the tornado's circulation affects the local air currents, the wind could first blow in one direction and then abruptly turn opposite that way. Pay close attention to these wind variations, particularly if additional warning signals such as darkening sky or the sound of an oncoming roar accompany them. Seek quick cover if you are outside and observe a notable, unexpected change in wind direction. Even in cases when a tornado does not materialise, such wind shifts often point to severe storms including strong straight-line winds, big hail, or plenty of rain. Always give your safety top priority, and be ready to respond fast when you see these warning indicators connected to winds.
