UK weather: Heavy snow causes UK-wide disruption

Heavy snowfall is hitting parts of the UK, causing road and rail disruption.
Police say driving conditions are treacherous in places as a band of wintry weather and very low temperatures sweeps westwards.
Hundreds of trains are cancelled, many schools are shut and forecasters say some rural communities may be cut off.
Kent, Surrey, Suffolk and Sussex are among the worst-hit counties, seeing up to 10cm of snow, while north-east England has received up to 8cm (3in).
Amber Met Office weather warnings are in place in those areas, meaning there is a possible risk to life and property.
A less severe yellow warning applies to a much wider area, covering much of Scotland, England and Wales.
In Lincolnshire, police helped 45 schoolchildren from their bus after it collided with a car and left the road. None of the pupils were injured, but the force said conditions were "particularly hazardous".
The UK is experiencing what's expected to be the coldest week of the winter, with snow moving west during Tuesday, increasingly spreading into Scotland and the Midlands later in the day.
Up to 40cm of snow could fall in north-east England and Scotland, between Wednesday morning and Thursday lunchtime, the Met Office says.
Temperatures dropped well below freezing on Monday night, with Northern Ireland, south west England and East Anglia logging figures as low as -6C. The lowest temperature was -8.9C and was recorded in Farnborough, Hampshire.
It is expected to get as low as -15C by midweek where snow has fallen.
BBC Weather meteorologist Gemma Plumb said: "On Wednesday and Thursday it is going to feel bitterly cold with a lot of areas seeing maximum temperatures below freezing.
"There will be heavy snow showers in the East, particularly in north-east Britain."
Motorists, meanwhile, are being urged to take extra care and in the worst affected areas, only travel if really necessary.
The RAC's Pete Williams advised drivers to check fuel levels, oil, tyre tread and pressure, coolant, lights and screen wash before setting out.
Hundreds of schools across the UK are shut, particularly in north-east England, Yorkshire, and the South East.
