Nearly all of Britain has been covered by snow and ice warnings - and the Met Office is urging people to be prepared for weather chaos.

The Met Office has issued yellow and amber snow warnings for much of the UK as the country prepares to be blanketed in as much as 40cm of snow this weekend.

A Met Office weather map shows a band of snow and hail making its way across Wales on Saturday evening before the first flurries hit the south of Greater Manchester at 8pm. By 8.15pm snow is forecast for the higher ground around Stockport, Tameside and Oldham, before the main band of snow and hail arrives around 8.30pm.
