What Does Tornado Watch Mean

Learn what a tornado watch means, the difference between watch and warning, how to be prepared, examples, statistics, and more.

Understanding Tornado Watch

When a tornado watch is issued, it means that weather conditions are ripe for the formation of tornadoes. It does not necessarily mean that tornadoes are imminent, but rather that they are possible in the designated area. This alert is typically issued by the National Weather Service (NWS) and covers a specific geographical area for a certain period of time.

Difference Between Watch and Warning

It’s important to differentiate between a tornado watch and a tornado warning. A tornado watch is a declaration that tornadoes are possible in the area, while a tornado warning means that a tornado has been sighted or indicated by weather radar. Tornado warnings are more urgent and require immediate action to seek shelter.

Be Prepared

During a tornado watch, it is crucial to stay informed and prepared for potential severe weather. Have a plan in place for seeking shelter, such as a basement or interior room on the lowest level of a building. Keep a weather radio or phone handy to receive updates from the NWS.

Examples of Tornado Watches

  • In May 2019, a tornado watch was issued for parts of the Midwest, including Kansas, Nebraska, and Iowa. Several tornadoes were reported in the region during the watch period.
  • In April 2020, a tornado watch was issued for parts of the Southeast, including Alabama and Georgia. Multiple tornado warnings were issued during the watch period, leading to property damage and power outages.

Statistics on Tornado Watches

According to the NWS, an average of 1,000 tornadoes are reported in the United States each year. Tornado watches are issued for large areas where conditions are favorable for tornado formation, helping to alert residents and emergency responders to the potential threat.


Understanding what a tornado watch means is essential for staying safe during severe weather events. By staying informed, prepared, and knowing the difference between watches and warnings, you can take appropriate action to protect yourself and your loved ones.
