Isolated tornadoes possible under severe thunderstorm watch; tornado watch vs warning explained

A severe thunderstorm alert is in place, with more than 43 million people across the eastern United States estimated to be affected this Saturday, according to Fox News. Forecasters warn of damaging winds, heavy rain, large hail, flash flooding, and even isolated tornadoes. The watch, in effect until at least 8 p.m., stretches from eastern Pennsylvania to southern Maine and includes the tristate area.

According to the National Weather Service (NWS), wind gusts could reach over 58 mph. Within the slight risk area, there is also a chance of isolated tornadoes and hail up to one inch in diameter. In addition to the localized risk of flash floods, minor urban and poor-drainage flooding is possible. While forecasters are warning of isolated tornadoes, it’s important to understand the difference between a tornado warning and a watch.

Tornado watch vs warning

According to the NWS, there are three key alerts to understand:

• Tornado Watch: Be Prepared! Tornadoes are possible in and near the watch area. Review your safety plan, check supplies, and be ready to act quickly. Watches cover large regions and are issued by the Storm Prediction Center.
  
  
• Tornado Warning: Take Action! A tornado has been sighted or indicated on radar. This is an immediate threat to life and property. Seek shelter in an interior room on the lowest floor of a sturdy building. Warnings are smaller, more targeted, and issued by local forecast offices.

• Tornado Emergency: Seek Shelter Immediately! This is the most urgent alert, issued when a violent tornado is confirmed and catastrophic damage is expected. Move to the safest location possible and alert others in the area.
