The mercury was expected to hover around minus 3 degrees in northern England on Saturday.
Snow and ice were forecast for the Highlands, Northern Ireland, western areas and the north of England, but the Midlands and eastern England were expected to be fine, if frosty.

Attempts to salvage another ship, the ferry Riverdance aground off Blackpool since Thursday, were postponed because of the bad weather.
