When we get into thunderstorm situations, especially during the summer months, you may hear Spectrum Bay News 9 meteorologists use the words "watch" and "warning."

They sound similar with respect to severe thunderstorms and tornadoes, but actually, they're quite different.

When we are placed in a "watch," Spectrum Bay News 9 meteorologists will provide live updates every 10 minutes. You'll also see text scrolling at the bottom of your screen.

A "watch" means conditions are favorable for severe weather or tornadoes. This is when you want to make sure you have a plan in place and know where you would go in the event of a severe thunderstorm or tornado warning.

A "warning" means a severe thunderstorm or tornado is imminent or occurring, and you need to seek shelter immediately in the safest part of your home. It's best to be in the lowest level, in an interior room or closet, and away from windows and doors until the threat passes.

What makes a thunderstorm "severe"? The textbook definition of a severe thunderstorm is one that has winds of more than 58 mph, or hail 1 inch in diameter or greater, and/or a tornado. Lightning is not taken into consideration for a storm to be severe.

All thunderstorms contain lightning.

A tornado warning means that a tornado either has been observed by a trained storm spotter or detected on radar.

When you are away from your TV, the best way to stay safe is to have the Spectrum Bay News 9 app on your mobile device or tablet and make sure notifications are turned on. That way, you'll get notified immediately of potentially dangerous weather.
