Keep a map nearby to follow storm movement in your area by monitoring weather bulletins. A tornado watch will be issued when tornadoes are possible in your area. You should stay tuned to radio or television for further advisories. A tornado warning is issued when a tornado has been sighted or is indicated by weather radar. If a tornado warning is issued for your area and the sky becomes threatening, move to your designated place of safety.
Many communities have sirens or whistles to warn the public of tornadoes.
Tornadoes also develop occasionally in areas where a severe thunderstorm watch or warning is in effect, so you should always remain alert for signs of an approaching tornado if threatening conditions exist.
