Heavy snowfall and freezing conditions have caused major disruption across almost all of Britain, with a warning of more snow on the way.
Bitter easterly winds continued to bring Arctic conditions and forecasters warned there is little chance of an early reprieve.
Many commuters worked from home, thousands of children could not go to school and motorists faced travel chaos as a number of roads were impassable.
Almost every corner of the UK woke up to between 0.8in (2cm) and 4in (10cm) of snow on Tuesday, with the east coast worst hit by flurries and sub-zero temperatures.
Some places in the south of England saw up to 4in (10cm) of snow due to a brisk wind pushing the showers inland.
In Scotland, Kinloss in Moray saw temperatures plunge to minus 13C overnight and during the day the highest temperature recorded there was minus 2C.
The warmest temperature on Tuesday was 2.8C in Anglesey, north Wales, while Cromer in Norfolk saw the mercury rise to 2.5C.
Forecasters have warned that more snow showers are expected across England, Wales and eastern Scotland on Wednesday.
Aisling Creevey, forecaster with MeteoGroup, said of the outlook for Wednesday: “We are expecting a maximum temperature of 1C in the south-east of England, the south-west could see 3C on the coast but sub-zero temperatures further inland. In the north-east of England, the maximum estimate is 2C. In Scotland, generally most places are not likely to get above minus 3C.”
Severe weather warnings have been issued by the Met Office for almost all regions of Britain.
