Snow prompts West Yorkshire travel warning
Motorists and train passengers across West Yorkshire are being warned of potential disruption as snowfall and freezing temperatures are forecast.
The Met Office said sleet and snow showers would become more widespread on Friday afternoon.
It has issued an amber warning of snow saying drivers should be prepared to alter travel plans.
The East Coast train company has advised passengers to check before travelling.
The company said it would lift ticket restrictions for all journeys on its trains which arrive in, or depart from, King's Cross station in London after 10:00 GMT.
East Coast urged passengers wherever possible to travel before 18:00 on Friday, as heavier snowfalls were predicted after that time.Allow extra time
A spokesman said: "We are constantly monitoring predicted weather conditions along our route, and the latest information we have is that heavier snowfalls are expected between Peterborough and the North East on Friday afternoon and evening.
"Our people are working hard to prepare our trains and stations as well as we can.
"Additional engineering teams will be based at key points on our route to keep trains moving, while Network Rail has snowploughs ready to keep tracks clear.
"Our advice to customers is please check for the latest information before setting out, and allow extra time to reach stations as road conditions are expected to deteriorate through the day."
The Yorkshire Ambulance Service has also urged people to take extra care to avoid extra pressure on the service.
David Williams, deputy director of operations, is heading the ambulance service's preparations.
He said: "We have plans in place to help us ensure we can continue to operate in the adverse conditions but ask that the public also make their own plans to ensure they don't need to call us unnecessarily for assistance.
"Our staff will be working extremely hard to get to local people who call upon us for help as quickly and as safely as possible.
"Understandably, hazardous driving conditions may lead to extended drive-times meaning it might take us a little longer than normal to reach patients in the worst-hit areas."
