It's a stunning sight - a cascade of water frozen in time in beautiful North Powys, as the Siberian weather system known as the 'beast from the east' plunged temperatures down to -7.

Walker Adrian Moller sent in these fantastic pictures of the Pistyll Rhaeadr waterfall in Llanrhaeadr-ym-Mochnant as many people will have never seen it before.

Local business owner Adrian, whose company 'Simply Ribbons' is based halfway along the Waterfall road, said it was a 'breathtaking' sight.

"On Wednesday we walked the two miles from our online business halfway along the waterfall road with the aim of seeing what effect the cold weather had on the waterfall at the end of our road.

"What meet our eyes was truly breath taking and well worth the walk. In the ten years we have been living and working up here we have never quite seen it like this before."

Elsewhere walkers reported similar sights across the country, with another fall in the Brecon Beacons at the foot of Pen-y-fan also freezing solid overnight.

Nearby Lake Vyrnwy recorded the lowest temperature anywhere in Wales earlier this week as the mercury plummeted to -6.9C while elsewhere in the UK Farnborough, Hants, saw the lowest overnight temperature of -8.9C, with a "wind chill factor" making Britain feel colder than the Arctic Circle as another storm system. Storm Emma, moved in towards the end of the week.
