The continent has been battling heavy snowfall. Reports say conditions have marginally improved in some regions.
Temperatures were still low, forcing more major delays on roads, railways and at some airports.
Britain was braced for black ice and floods as the thaw sets in.

Travellers faced further disruption after four days of chaos. The Met Office said weather warnings remained in place for much of the population.
Ireland's main airports reopened yesterday, although more than 50 flights in Dublin, mainly operated by Ryanair and Aer Lingus, had already been cancelled before snow and ice teams worked through the night to clear the airfield.
Irish police charged nine people after looters raided a Lidl supermarket and smashed through the roof with a mechanical digger during a national red alert for freezing weather.
Video footage posted online showed the digger breaking through the roof of the German retailer in west Dublin on Saturday while most stores were closed because of ice, snow and winds. The Irish Independent said a gang of men apparently used the digger to try to smash open a safe at the supermarket.
Italy was also still stuck in sub-zero temperatures, with a number of major roads blocked because of snow and black ice as it holds its election.
