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.
