Snow and icy conditions are set to cause further disruption across the UK as Storm Darcy brings more cold and snowy weather over the next few days. The Met Office has so far issued four national severe weather warnings for snow but further warnings are likely throughout the week. Amber warnings for snow are in place in central Scotland from 3am on Tuesday with road travel delays likely along with delays and cancellations to rail and air travel. About 5-10cm is expected fairly widely across the area, with up to 25cm in the worst-affected regions. The frequent snow showers that hit south-east England and East Anglia are expected to continue into the middle of the week with forecasters warning people to expect longer journey times by road, bus and train. Yellow warnings for snow and ice remain in place for most of the eastern half of the country until late on Wednesday night. Steve Ramsdale, a Met Office chief meteorologist, said: “With cold air across all of the UK any precipitation will fall as snow. Snow showers will continue to feed into eastern parts through the week.” Overnight temperatures will remain low throughout the week, with lows of -10C expected as far south as East Anglia. “Daytime temperatures will also be cold, only reaching 1 or 2 degrees Celsius for many early in the week. With strong winds as well the wind chill will make it feel much colder,” said Ramsdale. In south-east England, the icy conditions and heavy snow caused mass disruption of rail services. Southeastern strongly advised customers to not attempt to travel on its network, with many routes closed and no replacement transport available. Greater Anglia announced a disrupted service across all routes with a reduced timetable until further notice. On Monday, police in parts of Suffolk, Norfolk and Essex told drivers not to travel as roads became impassable due to settled snow. Road closures were announced in Norfolk, Lincolnshire, Cumbria, Derbyshire and Hertfordshire. Suffolk Highways said conditions were worsening, comparing the weather to the “beast from the east” of 2018, although the Met Office did not expect conditions to be as bitterly cold. The Met Office deputy chief meteorologist Jason Kelly said: “There is a chance of more organised snow affecting some western and south-western parts of the country as Atlantic frontal systems push into the cold air. There is a lot of uncertainty regarding which areas may see snow, but for now south-west England, south Wales and Northern Ireland look most prone.” Public Health England issued a cold weather alert for the whole of the country on Monday, saying it could have “a serious impact on health”. PHE’s Dr Owen Landeg said: “Cold weather can have a serious impact on health, particularly for older people and those with heart and lung problems, as it increases the risks of heart attacks, strokes and chest infections. “It’s really important during this particularly cold period to keep checking on frail or older neighbours or relatives, especially those living alone or who have serious illnesses.”
