A Met Office weather warning for snow and ice has been extended, with possible heavy snowfall expected throughout the weekend.

A yellow warning for the entire western coast of the UK was already in place for the early hours of today (Friday December 8) through to 6pm on Saturday.

But the Met Office has now updated the warning and predicted bitter temperatures and heavy snowfall over parts of the UK during Sunday – due to Storm Caroline, which has already hit the country with gale-force winds battering the Scottish coast.

So far today in the Chester and Ellesmere Port area, there have been light flurries of snow but no major disruption although police are dealing with a two car collision on the M53 between junctions seven and eight and there was another two car collision earlier this morning on the M56 westbound at junction 2.

A Met Office spokesperson said: "During Friday, increasingly frequent snow showers already affecting parts of Scotland, Northern Ireland and northern England will extend across many other northern and western parts of the UK.

"2-5 cm of snow is likely in places over the warning area. 10-20 cm is possible for some locations, mainly in northern Scotland, Northern Ireland, north Wales and perhaps the northwest Midlands.

"Icy surfaces are also likely to be an additional hazard, especially overnight. The heaviest and most frequent snow showers will progressively become confined to northeast Scotland during Saturday.

"A spell of heavy snow is possible over some central parts of the UK during Sunday.

"This could lead to road, rail and air travel delays, with the potential for vehicles to become stranded or public transport to be cancelled. Rural communities with limited access routes could become cut off."
