Snow and ice causing disruption across Wales

The Met Office has updated its yellow 'be aware' warning of snow with fewer parts of Wales affected:

• Conwy
• Denbighshire
• Flintshire
• Gwynedd
• Powys
• Wrexham

It says the public should be aware of the risk of disruption, particularly to transport.

The Met Office says Sennybridge had the lowest temperature in Wales last night. It fell to -5.8C.

The previous night it was -7.9C.

A brave border collie cross is lucky to be alive after survived a 300 feet fall off a snow-covered mountain. Georgie spent more than 18 hours marooned in snow - but was found alive after her ordeal.

The 10-year-old dog was found with a broken leg after an overnight rescue mission by her owner and friends. Owner Simon Pierce said her survival was "a miracle" after her fall in the Swansea Valley mountains covered with snow.

The drama began when he and his wife Heather, of Resolven, near Neath, went for a mountain walk with Georgie. Simon said, "There was a ledge of frozen snow - and she went through it. She dropped 30 feet in the air and probably rolled another 270 feet down the hill."

The couple feared they had lost their pet. But former miner Simon was determined to do all he could to find Georgie - and began the slow descent in snow. He scoured the mountainside for four hours until being halted by darkness.

Then her returned with friends to find Georgie in the morning to carry her back to his car.

The temperature plunged to -7.1C last night at Sennybridge in Powys.

The Met Office has a yellow 'be aware' warning of ice across Wales. It says the public should be aware of the risk of difficult driving conditions and slippery surfaces.

Temperatures will plunge below freezing on Friday night as the Met Office warns that severe cold weather and icy conditions could increase health risks to vulnerable patients and disrupt services.

Many areas will struggle to rise above zero overnight, while some areas of high ground in Wales could see as much as 4in-6in of snow.

The Met says although temperatures are "colder than average", and there are more snow and ice warnings than this time last year, the current weather is "typical British winter weather".

Wales will be 0C (32F) in some parts, but other areas such as Aberystwyth will be 2C (35.6F) as it benefits from some shelter from Northern Ireland, and Holyhead is expected to be as high as 4C (39.2F).

Health authorities have urged people to help vulnerable family and friends to keep warm.

Tonight: Mostly dry and clear this evening. During the early hours, a band of rain, sleet and snow will move southeastwards, with snow settling in places, especially over hills. A fairly widespread frost will develop, with localised icy patches likely. Minimum Temperature -4 °C.

Saturday: Another cold day with sunny spells and scattered wintry showers, mainly in the west, where locally heavy and perhaps thundery. Showers possibly falling as snow, especially over the hills. Maximum Temperature 7 °C.

Outlook for Sunday to Tuesday: Cold, with sunshine and isolated wintry showers. Overnight frosts with isolated freezing fog and icy patches. Outbreaks of rain, sleet or snow are likely on Tuesday.

The Met Office has issued a yellow 'be aware' warning of icy stretches on untreated roads.

It says there could be tricky driving conditions this morning. The areas affected are inland from the Welsh coast.
