Tornado warnings and watches are both issued by the National Weather Service (NWS) to alert people to the possibility of severe weather. A tornado warning is issued when a tornado has been sighted or indicated by weather radar. It is important to take immediate action when a warning is issued. A tornado watch is issued when conditions are favorable for the development of a tornado. It is important to remain alert and be prepared to take action if a warning is issued.
The main difference between a tornado warning and watch is the level of urgency. A warning means that a tornado is imminent and people should take cover immediately. A watch means that the conditions are favorable for a tornado and people should be prepared to take action if a warning is issued.
