9. The Sudden Drop in Temperature
Another crucial natural warning indication that a tornado might be on approach is a rapid and obvious drop in temperature. Often fairly dramatic, this temperature change can happen quickly—sometimes in a matter of minutes. The dynamics of the intense thunderstorm generating the tornado define the phenomena. The storm takes cooler air from higher elevations as it gets stronger, which then falls and spreads out at ground level. With the warm, humid conditions usually preceding major storms, this chilly air outflow can produce a striking contrast. Sometimes the temperature drop is really notable, maybe ranging from 10 to 20 degrees Fahrenheit in a brief span. It is sometimes accompanied by an obvious rise in humidity, which could make the air feel thick and stifling. This mix of decreasing temperature and more moisture indicates that the storm is strengthening and that conditions are getting more favourable for tornado development. Though they can happen with every violent thunderstorm, not all temperature declines point to an approaching tornado. It should be taken extremely seriously, though, if this abrupt cooling is seen alongside other warning signals as darker sky, severe winds, or the sound of an oncoming roar. If you feel a fast and notable drop in temperature during severe weather, particularly if it is accompanied by an increase in wind speed or a change in wind direction, you should be aware and ready to find cover rapidly. Pay close attention to this temperature variation and other environmental signals to guarantee your safety; it may be one of the last cautions you get before a tornado strikes.
10. The Electrical Interference
Electrical interference is one often disregarded but maybe important warning indicator of an oncoming tornado. The strong electrical activity inside the severe thunderstorm creating the tornado causes this phenomena to show itself in several forms. Strong electromagnetic fields produced by a storm can interfere with electrical systems and equipment. On radio and television transmissions, one typical indication of this interference is static. On AM/FM radio, you may find more buzzing or crackling; on your TV, your signal may get distorted or cut off totally. On non-digital systems especially, this is clearly evident, although it can even impact digital broadcasts. Cell phone reception could also start to vary or fail totally. Unaccounted for power spikes in your house or flickering lights can also be indicators. These variations arise as the electrical field of the storm interacts with electricity cables and systems. Sometimes you might even notice a rise in the static electricity around you. When you touch metal things, this can produce little static shocks or cause your hair to stand on end. Although electrical interference by itself does not ensure a tornado is approaching, it is evidence you are in the middle of a strong electrical storm, the kind that could generate tornadoes. Should you observe these electrical disturbances, particularly in conjunction with other warning indicators such as darkening sky or high winds, it is advisable to be vigilant and ready to find cover. If other communication systems are compromised, pay close attention to battery-powered weather radios or emergency notifications on your mobile device as these may be your most consistent sources of information. Remember, a crucial natural indication to be aware of under very severe weather conditions is electrical interference, which can happen before official warnings are released.
