Britain is enduring more snow and sub-zero temperatures at the start of another week of bitterly cold weather.

Snow swept across southern Scotland during the day on Monday, disrupting air, rail and road travel, and is forecast to move into northern England overnight.

The death toll during the big freeze rose to at least nine as it was revealed that a man had died while trying to clear snow outside his home in County Durham on Sunday and an elderly man was found dead in the snow at a caravan park in Humberside.

The Met Office said there are between 10cm and 40cm of lying snow in the central lowlands of Scotland, around 32cm in Edinburgh and 11cm in Glasgow.

Heavy snowfall and blizzard conditions in Glasgow and Edinburgh closed airports in both cities.

Glasgow Airport reopened at 2pm - but passengers were advised to check with their airline before travelling because of ongoing disruption to services. Edinburgh Airport reopened at 6pm and Dundee, Inverness, Kirkwall and Campbeltown airports remained closed.

Motorists in Scotland are advised to drive only if their journey is absolutely necessary, and roads throughout the country are closed.

Snowfall of 1cm to 3cm is expected across northern England on Monday night, said Tiffany Curnick, a forecaster with MeteoGroup.

She added: "Temperatures have commonly between around zero or minus 2C during the day, and in North Yorkshire there have been readings as low as minus 8C.

"It's going to remain cold, with no sign of a let-up in the temperatures. Overnight we will have readings as low as minus 13C in Scotland, and minus 5C and minus 7C further south."
