Tornado Watch vs. Warning: Understanding the Difference

According to the National Weather Service, a tornado is defined as a violently rotating column of air that touches the ground and is usually attached to the base of a thunderstorm. For those living in “Tornado Alley,” or the central region of the U.S., you’re all too familiar with tornadoes. While every state can experience them, certain states, like those in Tornado Alley, are more prone to tornadoes.

Regardless of where you live, staying prepared for tornadoes is key to keeping you and your loved ones safe. Part of being prepared is adhering to local and national weather service advisories for a tornado watch or warning. But what exactly is the difference between the two?

Keep reading to learn more about the differences between a tornado watch and warning and how to stay prepared if one makes landfall.

What Is a Tornado Watch?

A tornado watch is issued by the National Weather Service (NWS) when the surrounding environment has the proper elements for creating a tornado. It’s important to understand that a tornado “watch” doesn’t mean a tornado has been spotted or made landfall. Rather, it means current weather conditions are favorable for one to form.

The purpose of a tornado watch is to give you and your families enough time to properly prepare for severe weather. A watch generally lasts between four and eight hours. We know this can feel overwhelming, but meteorologists and other weather specialists monitor your area and will provide up-to-date information on your current weather conditions.

What Is a Tornado Warning?

On the other hand, a tornado warning signifies that a tornado has been spotted in your area or that landfall is imminent. If a tornado warning is issued, you must take immediate action to ensure your and your loved ones’ safety.

The Differences Between a Tornado Watch and Warning

When severe weather begins brewing, understanding the difference between a tornado watch and warning can be lifesaving. Although they sound similar, these terms indicate different levels of risk and require differing responses. Knowing the difference can save lives and reduce panic throughout your city or county.

How to Stay Prepared

Staying prepared for a weather emergency is the best thing you can do for your family. If you know tornado season is approaching, it’s a good idea to stock up on the essentials, like bottled water, paper products, canned food and any first aid items.

Make sure to download local and national weather apps and set up alerts for your phone. If your Wi-Fi or power goes out, make sure you have a battery-operated radio to get the latest news in your area. The National Oceanic and Atmospheric Administration (NOAA) offers a battery-powered or hand-crank radio that broadcasts live weather updates 24/7.

If you live in an area prone to extreme weather like tornadoes, your city likely has civil defense sirens. These sirens are designed to go off in extreme weather conditions to warn you and your family that it’s time to shelter immediately. Be sure to keep an open ear for their warning.

It’s vital that you identify a safe room in your home that doesn’t have windows. If a tornado nears your home, it’s possible for power lines, trees and other debris to fall on your house or crash through windows. That’s why identifying a safe room and an emergency plan is important. Don’t go outside to assess any damage until local sources say it’s safe.
