Wales weather: 3,000 without power after more snow
More than 3,000 homes in north Wales are without power following another night of snow.
Scottish Power say they believe a tree has fallen onto power lines in the Llangollen area affecting customers there and in the Dee Valley.
On Friday about 600 customers were without power after a separate problem.
Further snow has fallen across the country overnight, following Friday's widespread disruption which hit roads, rail and schools.
A band of snow has moved southwards during the night with heavy snow falling in Powys and some in the Gwent Valleys.
Emergency services warning that many roads are treacherous and people are being warned to travel only if necessary. North Wales Police who were called out to help stranded motorists in some cases found themselves in difficulties coping with the conditions.
Forecasters say the weather should turn much colder, bringing the risk of ice.
BBC Wales weather presenter Sue Charles said: "We've had some very disruptive weather over the last 24 hours.
"There has been fresh snowfall across north east Wales overnight, and that band slipped south eastwards into Powys and the Valleys.
"The Met Office has downgraded its warning for north east Wales to yellow.
"The snow will gradually ease through the day, but with 10-20 cm of lying snow at lower levels - the heaviest in Wrexham and Flintshire - mixed with some very strong winds - drifting likely - and still causing disruption.
"Turning much colder overnight, a widespread frost is likely and ice could also cause a few problems."
Ms Charles said it would be drier on Sunday with just a few snow flurries possible in the east, but it would be much colder with highs of between 1 and 3C.
It will stay cold next week, she added, but largely dry and temperatures will begin to return to normal over the Easter weekend.
About 600 customers - mainly in the Dee Valley - were left without power for a time on Friday with the Dee Valley the worst affected area and rail travel on the North Wales Coast line was disrupted.
Scottish Power said most of those customers had now had services restored.
The company said they are working with the local authorities to try to get access and their engineers are trying to fix the new problems affecting services.
More than 3,000 customers were affected, the company said.
On the roads, Mid and West Wales Fire and Rescue Service said there had been a few traffic collisions on Friday night and early on Saturday.
The worse incident saw a person taken to hospital after a two-vehicle crash on the A458 between Welshpool and Llanfair Caereinion, Powys, at about 01:20 GMT.
In Gwynedd, a number of roads are closed due to the snow.
They include the A4212 Trawsfynydd to Bala, the B4391 Lon y Berwyn at Llandderfel, Lon y Mignant, Blaenau Ffestiniog, to the A4212, the A5 Bethesda to Llyn Ogwen and the A4086 Nant Peris to Pen-y-Pas.
Gwent Police said there had been a few road collisions on Saturday but none were serious. Monmouthshire appeared to be the county worse hit by snow, it said.
Flintshire council said its street scene teams had been working around the clock since Thursday evening with 13 gritters and 36 agricultural ploughs treating and clearing routes.
Priority routes are passable with care, but conditions remain difficult. Fallen trees have also caused additional problems on some roads.
The authority said there would be no collections of any type on Saturday, but it has asked for residents to leave their black bins out because collections could resume on Monday.
Properties that did not receive a recycling collection on Friday or Saturday are being informed that collections will now take pace next Friday or Saturday.
Trade waste collections will resume on Monday and Tuesday.
Denbighshire council is urging people in the south of the county only to travel if absolutely necessary.
The A525 to Llandegla remains open, as does the A494 to Corwen and main A and B roads to the north of Ruthin.
However, many of the roads in the south are closed due to the severe wintry weather.
"Teams of council staff have been working around the clock, working in atrocious conditions to try and keep the roads open in the south of the county, but the sheer amount of snow that has fallen, coupled with snow drifts, have hampered those efforts," said a council spokesperson.
Over 200 schools closed on Friday, and there were several weather-related road crashes.
The snowfall is also expected to be the heaviest for the time of year in north east Wales since 1979.
Two flood alerts were in place in areas around the rivers of north west Wales, from Abergwyngregyn to Aberdaron as well as on the River Erch at Abererch in Gwynedd.
