The states in Tornado Alley can see 50 or more tornadoes a week during tornado season. Some of these tornadoes are big, but most are small. Many people watch for tornadoes during tornado season. Meteorologists, scientists who study weather, watch weather radar for possible tornadoes. Radar is a device that tracks storms and weather.
Spotters are people who are sent out to different areas when conditions are right for tornadoes.
The spotters watch the clouds carefully and report any funnel clouds they see. When conditions are right for tornadoes to form, the National Weather Service will issu0e a tornado watch. If meteorologists see tornadoes on radar and spotters see the tornadoes, a tornado warning will be issued. Sirens will sound in the towns in danger. When the siren sounds, people in the affected areas should take cover immediately.
