UK weather: Lows of -9.8C recorded yesterday, Met Office reveals - as warnings remain in place
Motorists have been urged to drive safely as police said they have been dealing with a "lot of accidents" in icy conditions on the roads.
Surrey Police issued the warning as the Met Office said ice will affect many areas this morning, meaning it's "worth leaving extra time for any journeys that you have planned".
The national weather service added on Twitter that many places will see some "winter sunshine" after a "frosty start" to the day.
Wintry showers can be expected in areas exposed to the brisk northwesterly wind and there will be snow in places.
Surrey Police wrote on Twitter: "This is snow joke, baby it's cold out there. Please take care on the roads, the gritters are out and about but we are dealing with a lot of accidents at the moment."
Yesterday morning was the coldest of the year so far with "plenty of wintry hazards around during the day".
The temperature plummeted as low as -9.8C in the village of Topcliffe in North Yorkshire.
Yellow weather warnings covering much of the west of England and large parts of Wales will be in place until midday today - and "snow showers and icy stretches may cause some disruption".
A yellow weather warning covering the south of England will be in place until 10am, and "ice is likely to cause difficult driving conditions".
Much of Northern Ireland and northern Scotland are also covered by yellow warnings.
The Met Office has said further weather warnings for snow and ice are likely to be issued for tonight.
Forecasters have warned temperatures could stay below average into next week in parts of the UK as the cold spell continues.
