00:00Well, with storms like we had over the weekend, sometimes when we're not talking about tornadoes,
00:06we're talking about wind anywhere from what you were seeing on the left side of your screen
00:10with the wind kind of ruffling the fur of the dog there to actual damage being done
00:15to a roof and that flag really blowing in the wind.
00:17Now, when we talk about severe weather, a lot of times we're talking about damaging
00:21wind gusts and this being one of the likeliest risks that we will see.
00:25But what exactly does that mean?
00:26Well, you might also hear us call them straight line winds.
00:28It's one in the same and damaging wind gusts or straight line wind damage, that's actually
00:33more common than tornado damage and the speeds that we're talking about, 50 to 60 plus miles
00:39per hour.
00:40That's when we get into damaging wind categories, but you can actually kind of estimate wind
00:44speeds just based on visual clues.
00:46We'll go through a couple examples.
00:47So first of all, we have just a light breeze, right?
00:50That's when you're outside.
00:51It's kind of a nice day.
00:52Some leaves might be kind of ruffling in the wind, four to seven mile per hour winds, very
00:56light.
00:57And then another breeze is maybe when you have an umbrella and it's kind of difficult
01:01to keep the umbrella working, right?
01:02Like it might be flipping inside out, things like that.
01:05That's when we get to 25 to 31 mile per hour winds.
01:08Then gale force winds, for example, we often talk about with, you know, tropical storms
01:12that are forming.
01:13This is much stronger.
01:14We're talking about 39 to 46 mile per hour winds and trees are going to be swaying.
01:19Traffic lights might be blowing around as well.
01:21Here's a couple more examples.
01:23So a severe thunderstorm, there's actually criteria, right?
01:26For a severe thunderstorm warning, winds have to be 58 miles per hour or greater.
01:31You might see power lines swaying dangerously.
01:34It can reduce visibility because of dust, rain or debris blowing around.
01:39Then we get to destructive thunderstorms.
01:41This is 80 mile per hour wind gusts or stronger.
01:44And that's when we talk about large trees uprooted.
01:47A category one hurricane, of course, is going to be bending trees.
