A video has captured a metal roof crashing through gardens as Storm Eunice batters Wales.
The incident in Hollybush, Cwmbran happened on Friday morning, and has caused damage to several gardens.
A witness says the roof "would kill someone straight away" if it had hit them, and still had nails and screws attached as it flew over from a local farm.
Storm Eunice has also blown over two lorries on the M4, toppled a concrete wall, blown a roof off three houses, brought down trees across Wales and forced the closure of many roads.

The roof has caused damage to fences from several neighbours on Brynglas in the Hollybush area of Cwmbran with one fence completely knocked down.
John Ashley, 37, captured the footage on home CCTV. He said: "It's damaged our fence and some of the items in next door's garden as well.
"If that was around the front it would have taken a car out easily. The way it just sliced through our fence like a hot knife through butter really. It's a bit nervy.
"I was just out there trying to move it to make it a bit safer and my wife saw a bit more of the roof had come off but thankfully, it blew the other way.
"I just heard my wife scream as she heard this horrific crash and there was this huge piece of corrugated roof in the garden. There's still nails and screws in the roof so that was a bit of a concern as well.
"It took a few of the neighbours to move it and we have managed to make it safer.
"I think people need to stay safe. There's a lot of people on social media saying that the storm is nothing, but of that hit someone it would kill them straight away - the edging is so sharp."
This comes as parts of Wales are under a "rare" red alert as Storm Eunice hits the country.
Winds of up to 100mph and flood warnings are in place across Wales for the storm on Friday, February 18. More details here.
Storm Eunice is set to be one of the "most impactful storms to affect southern and central parts of the UK for a few years."
Just before 11am on Friday the Second Severn Crossing on the M4 was closed meaning that for the first time ever both crossings have been shut.
