Merry Christmas! Weather warnings spark fears of festive getaway travel chaos Network Rail has warned of disruption to services that could see trains delayed, or cancelled and companies running amended timetables. The Met Office has warned an area of low pressure developing over the Atlantic today and into tomorrow will bring with it very strong winds and heavy rain to much of the UK from Monday morning through to late Tuesday morning. Severe weather warnings have also been issued for wind and rain across the southwest and northern areas of the UK over the next few days. "The public should be aware of the potential for significant disruption to travel due to the very strong winds and also the risk of some flooding issues due to the heavy rain," the forecaster said. There are also concerns that the wet and windy weather could lead to disruption on the roads with an estimated 13 million people expected to travel between December 24 and 26. Eddy Carroll, chief forecaster with the Met Office, said: "We can expect stormy weather in many areas to start the Christmas week, but looking forward to Christmas Eve and Christmas Day we are expecting it to turn colder, with a mix of wintry showers and sunny spells but for wind speeds to drop. Britain could also see a white Christmas as there is a chance of snow - but it is unlikely to be widespread. "It's not going to be cold enough for widespread snow, it's more of a showery picture," said Chris Burton, from weather forecasters MeteoGroup. There will be a bit of sleet and snow on the higher ground, such as the hills of Wales and in northern England, and wintry showers will be heavy in the mountains of Scotland. Officially, a white Christmas is defined as just one single snowflake falling from the sky.
