Coalnado! Construction worker captures incredible moment dust devil spins over the mine in West Virginia
- The dark-colored dust devil was spotted over a coal supply that had been cleared away and unloaded on Monday in Elkhorn, West Virginia.
- Randy Walters, the hean equipment operator who made a 15-second whirlwind video said it disappeared 10 seconds after he stopped recording
- Dusty devils are considered harmless and rise from the surface in warm, dry weather
- Tornadoes, on the other hand, are descended from the basis of thunderstorms
A dark colored dust devil was spotted around a coal mine in West Virginia on Monday in what was a & # 39; coalnado & # 39; is called.
Video footage made by Randy Walters shows coal swirling over a surface mine in the Elkhorn area.
& # 39; It was very loud, & # 39; Walters told Storyful. & # 39; I heard it before I saw it. & # 39;
The dark colored dust devil was spotted in West Virginia. After dubbed a & # 39; coalnado & # 39 ;, the whirlwind was seen Monday afternoon near a surface mine in Elkhorn.
Walters said he dusty devils & # 39; pretty regularly & # 39; but they are usually only two or three feet long.
The & # 39; coalnado & # 39; disappeared 10 seconds after the 32-year-old heavy equipment operator, Walters, stopped recording the 15-second video that afternoon, he said on Facebook.
Although it may not be clear, it is not a tornado at first glance from the McDowell County man's clip, but the sky remains blue in the background.
The whirlwind was about a coal supply that had been cleared and loaded, heavy equipment operator, Randy Walters said about the 15-second video. He says it disappeared 10 seconds after he stopped recording
Tornado's descend from the base of thunder and appear thinner when they reach the ground.
This weather system captured on video is similar to a tornado, but dusty devils usually form on the surface in warm, dry weather.
Walters told Storyful that he dust devils & # 39; pretty regularly & # 39; but they are usually only two or three feet long
They rise when the sun heats one surface faster than the other and in this case the dark matter of the coal absorbed more rays and formed hot air columns.
When heated air pockets are caught by wind that changes direction, this can create the rotating columns that can be seen in the striking images.
But the whirlwinds in the & # 39; coalnado & # 39; are much weaker than tornadoes, WVVA Chief meteorologist Katherine Thompson says.
Although people are advised to keep their distance, they are considered harmless and only known to cause occasional isolated damage to houses and trees.
