Passengers are facing cancellations and delays after several major airports in England had to shut their runways as snow and freezing rain swept parts of the UK.
An amber weather warning is still in place from the Midlands up to Carlisle. Less severe yellow weather warnings are also in force for parts of Scotland, Northern Ireland and elsewhere in England.
Until mid-morning on Sunday, no planes could leave Manchester Airport with all incoming flights being diverted elsewhere. Runways at five other airports were also temporarily closed due to snowfall.
The wintry conditions have also led to road closures in the north of England, and caused disruption and cancellations on some rail lines.
The weather warnings in place are:
- An amber warning for snow covering most central and northern England, including the Midlands and the north-west cities of Liverpool and Manchester, until midnight on Sunday
- Less severe yellow warnings for snow covering parts of Scotland, Northern Ireland, Wales, and most of northern England including Leeds, Sheffield and the Lake District also until the end of the weekend
Amber warnings are more serious than yellow warnings and indicate a possible risk to life, as well as more significant travel disruption.
Fresh yellow weather warnings will also come into force in some areas on Sunday and Monday.
There was 16cm (6.3in) of snow in Bingley, West Yorkshire as of 09:00 GMT on Sunday, while overnight the lowest temperature recorded was in Loch Glascarnoch, Scotland (-11C).
The Met Office has said some rural communities could be cut off, with up to 40cm of snow on ground above 300m, before conditions ease later on Sunday.
Further accumulation of snow through the night was expected across the higher ground of northern England and the Southern Uplands in Scotland.
Manchester Airport warned that “some departures and arrivals may still be subject to delays” after it was forced to close its runways, and urged passengers to check with their airline for updates on their flight.
More than 20 flights in and out of the airport have been cancelled and over 200 delayed as of 15:30 GMT, according to tracking website FlightAware.
More than a dozen Manchester-bound planes have had to land at London Heathrow, Gatwick, Birmingham, Dublin, Glasgow and Paris.
As a result of heavy snowfall overnight, Liverpool, Bristol, Birmingham and Newcastle airports temporarily closed their runways. All have since reopened.
Leeds Bradford Airport reopened its runway shortly after 14:15 GMT but said disruption was expected throughout the day as it continued to mitigate heavy snowfall.
Overnight, snow closed the A628 Woodhead Pass, which connects Greater Manchester and South Yorkshire through the Peak District, in both directions between the A616 at Flouch and the A57 at Hollingworth.
The A66 in County Durham and Cumbria is closed between the M6 and A1M, while the A1 was closed southbound between the A639 North Elmsall and the A1(M)/A638 Doncaster in South Yorkshire due to a collision involving a car and a HGV, according to National Highways.
Stuart Irons, from National Highways, told BBC Breakfast on Sunday that 500 gritting lorries planned to be out across the UK and they have stockpiled more than 240,000 tonnes of salt as part of preparations.
He said: “Predominately it is snowing quite heavily in the north. The rest of the network is looking quite well, it is starting to ease from the Midlands down.
“But obviously as it does start to ease and it does thaw out there is a risk of flooding and there could be some freezing conditions later so we are advising motorists to be aware of areas with excess water.”
In Merseyside, two safety meetings were held on Sunday morning to assess whether the snow and travel conditions would affect the Premier League clash between Liverpool and Manchester United.
The match was given the go-ahead, but Avanti West Coast said there would be limited trains going to or from Liverpool Lime Street station after all services were cancelled on Sunday morning due to issues at its depot.
National Rail said poor weather is affecting LNER, TransPennine Express and Northern services.
Through Saturday night into Sunday morning heavy snow affected much of England and northern Wales.
There is currently around 5cm of snow in many cities including Leeds and York, according to BBC Weather.
The heaviest snow is expected in higher parts of Wales, the Midlands and northern England, with up to 30-40cm possible over the mountains of north Wales, the Peak District and the Pennines.
At lower levels some disruptive snow is likely, but in places this will mix with rain – falling on cold surfaces, leading to the threat of ice.
Heavy rain and thawing snow could lead to flooding in some parts of north-west England and Wales, while localised snow and ice warnings cover parts of Scotland, where it will remain cold.
Temperatures are forecast to dip again from Monday, and UK Health Security Agency (UKHSA) amber cold weather health alerts for all of England remain in place.
