FORECASTERS have extended a weather warning for snow and ice across Wirral this weekend.

Snow showers are expected to cross the North West between 12am to 11.55pm on Sunday, December 10.

It is expected that 2 to 5cm of snow will fall with 10 to 20cm possible over high ground.

Icy surfaces will be a likely hazard especially as temperatures drop overnight.

Commuters are being warned that roads and railways are likely to be affected with longer journey times by road, bus and for train services.

It is likely that there will be some icy patches on untreated roads, pavements and cycle paths.

Pedestrians are being warned of possible injuries from slips and falls on icy and snowy surfaces.

The chief forecaster said: "During winter weather which brings snow showers, it is not uncommon for snow amounts to vary considerably across short distances.

"On Friday and Saturday, the snow showers could lead to snow accumulations which vary markedly across the warning area.

"Strong northwest winds may cause drifting of the snow in places with blizzard conditions possible across northern Scotland.

"A band of rain, heavy at times, is expected to move eastwards over the UK.

"With cold air in place, a spell of snow looks likely to develop on its northern edge.

"1 to 5 cm is possible quite widely, and up to 10 cm in places.

"Over higher ground, 20 cm is possible in a few places.

"There is currently a good deal of uncertainty over the precise track of the areas of rain and snow."

Storm Caroline is expected to hit northern Scotland today with gusts of up to 80mph.

Snow and falling temperatures are also expected to affect the west of the country on Friday as Storm Caroline, the third named storm of the season, passes through.
