Often, on TV, a meteorologist will talk about a severe thunderstorm warning.

Obviously, that means it's a pretty serious storm and likely dangerous too, but what does it take for a storm to get that classification?

They are very specific about a few things for a storm to earn the severe title.

First is hail, and not just any hail. For a storm to be considered severe, the hail must be at least 1 inch in diameter.

Wind is another deciding category. If a storm has winds greater than 58 miles per hour, it is considered severe.

And lastly, if a storm produces a tornado, it is considered a severe thunderstorm.

Rain is not part of the severe criteria. That's handled by a different type of warning.

Lightning isn't included either, because every storm producing lightning would be considered severe.

Even though rain and lightning aren't part of the severe warning, both can be deadly.

So as always, enjoy the weather this monsoon, safely.
