A huge waterspout can be seen off the coast of the US after it was caught in remarkable footage.
The amazing weather event is relatively rare and was caught on camera by fortunate people passing by near the towns of Destin and Henderson in Florida.
Particularly dangerous if they reach land, swimmers and boats are advised to keep well away if they can, as are passing aircraft.
Videos recorded by Boo Freeman and Ken Creer show the water twister coming down from ominous-looking storm clouds that fill the sky.
Freeman can be heard in the video saying "That’s a biggun'" as he noticed the marvel going past the Silver Shells Beach Resort.
The National Weather Service in Pensacola noted the incident occurred around 6am local time on Tuesday, August 16.
They warned people in boats about further waterspouts in the area after more storms are expected.
They are essentially tornadoes that form over water, though there are two types, according to the US National Ocean Service (NOAA).
'Fair weather waterspouts' form are not associated with thunderstorms and are different to 'tornadic waterspouts' as they form on the surface and work their way upwards.
Tornadic waterspouts go the other way, forming in a thunderstorm and working their way to the surface.
NOAA explained: "By the time the funnel is visible, a fair weather waterspout is near maturity.
"Fair weather waterspouts form in light wind conditions so they normally move very little."
Despite the name, a waterspout is not filled with spinning water but with high winds, though needs a relatively high temperature of water and significant humidity to form.
"If a waterspout moves onshore, the National Weather Service issues a tornado warning, as some of them can cause significant damage and injuries to people.
"Typically, fair weather waterspouts dissipate rapidly when they make landfall, and rarely penetrate far inland."
They can last up to around 15 minutes and travel around 15 knots, with wind speeds of roughly 50 miles per hour.
In similar scenes, another waterspout was seen by witnesses Martin Jezard and Mark McCartney near Fowey, Cornwall, on Tuesday.
Martin said: "The weather is often a bit iffy during Regatta Week but this afternoon’s water spout, basically a tornado over water rather than land is next level. Wicked Witches of the South West beware."
Experts say the phenomenon is more common in places like Florida, the east coast of Australia and the islands of Greece.
