Ice warnings as temperatures fall below zero across UK

Temperatures have plunged below freezing in parts of the UK amid warnings that drivers could face treacherous conditions on icy roads.
The lowest recorded temperature was almost -5C in Perthshire overnight with "widespread" frost hitting large areas of the UK, the BBC Weather centre said.
The Met Office issued yellow warnings to "be aware" of ice in all areas.
Widespread icy patches could form on untreated surfaces, especially where snow has fallen, the Met Office said.
Forecasters predict the temperature could drop below freezing even in southern cities on Sunday night and could fall as low as -10C in rural areas.
It follows wintry showers across northern Ireland, Wales and eastern England on Saturday, with the town of Leek in Staffordshire recording the day's heaviest snowfall of 12cm (4.7in).
The Met Office has warned drivers to take extra care on the roads.
A section of the M62 near Huyton was closed after an accident. In Derbyshire, part of the A6024 near High Peak was closed and in south Yorkshire the A631 near Beckingham was closed - both because of ice.
BBC Weather's Philip Avery said some of the lowest recorded temperatures overnight had been in areas where snow had already fallen.
He said temperatures had fallen to below freezing in parts of northern Scotland, while in much of England, Wales and Northern Ireland it was either close to or below zero.
Meanwhile, a cold weather alert for parts of England has been issued, with the Met Office saying there is a 90% chance that severe weather until 12:00 GMT on Wednesday could "increase the health risks to vulnerable patients and disrupt the delivery of services".
The amber - level three - alert is one below a national emergency and indicates social and healthcare services should target "high-risk" groups, such as the very young or old, or those with chronic diseases.

How to drive in snow and ice

 

• Balance your speed - too fast and you risk losing control, but if you go too slow you risk losing momentum
• Start gently in second gear, avoiding high revs. Stay in a higher gear for better control
• Only use the brake if you cannot steer out of trouble
• Increase the distance at which you follow other vehicles
• Plan your journey around busier roads, which are more likely to have been gritted
• On a downhill slope, get your speed low before you start the descent, and do not let it build up
• In falling snow, use dipped headlights or fog lights, but switch off if conditions improve
