Travel disruption is expected during Monday’s morning rush-hour as yellow warnings of ice, fog and snow are in place for much of the UK.
The Met Office issued the alerts as temperatures are expected to stay well below freezing overnight and combine with wintry showers to create icy conditions.
Snowfall on Sunday evening forced airports to close their runways and left drivers struggling to get through.
The warnings come as four children were taken to hospital in critical condition after being rescued from a lake in Solihull in the West Midlands on Sunday afternoon after falling through ice.
Richard Stanton, area commander for West Midlands Fire and Rescue Service, advised the public following the incident: “We know that the weather forecast for the next few days is expected to be bitterly cold, please, adults and children alike, stay away from open water, under no circumstances venture on to ice regardless how thick or safe you think this ice may be.”
Road users in the South East were being asked by National Highways not to travel unless it was essential due to heavy snow already falling on Sunday evening, with up to 10cm of snow forecast.
Kent was being particularly hard hit, with snow severely impacting the M2, the M20 around junctions 8 and 9, the A21 and the A249, with drivers struggling to get through, the organisation said.
National Highways duty operations manager for the region Gina Oxley said: “We have been out gritting throughout the afternoon and we’re continuing to treat routes so we can reach the worst-affected areas and support our customers with their journeys.
“For anyone thinking of travelling tonight, our advice would be not to unless absolutely essential as heavy snow is expected to continue until 9am tomorrow.”
Airports were also being affected, with both Gatwick and Stansted having to close their runways to clear snow on Sunday.
The Essex airport said in a statement: “London Stansted Airport’s runway is currently closed to allow for snow clearance due to weather conditions and all flights are currently suspended.
“Delays to flights were experienced earlier due to de-icing of aircraft which is a ground handler’s responsibility and safety of aircraft and passengers is paramount.
“Passengers are advised to check with their airline for current status of their flights.”
Gatwick posted on Twitter: “Sunday 11/ Monday 12 December: Snow and freeezing weather may cause disruption at the airport. Passengers are advised to check flight status with their airline – and also local travel conditions – before departing for the airport.”
The yellow warnings are in place from Sunday until Monday morning for northern and south-western Scotland, Northern Ireland, north-eastern England, the Midlands and South West as well as London and the South East.
Met Office meteorologist Rachel Ayers said: “It will continue to be a very cold day, with maximum temperatures of 1C to 4C on Sunday, and, as we head into the evening, we see persistent rain, sleet or snow in the far South East of England, which is what we have a yellow warning out for from 6pm on Sunday.
“We could see 2cm to 5cm (of snow), perhaps up to 10cm in some places, with Kent and Sussex most affected, with areas most exposed such as North and South Downs and higher ground going to see the more significant accumulations.
“There will be ice forming, particularly near to the coast where there is rain and sleet, and freezing temperatures which could cause some travel disruption to start Monday with that valid until 9am.”
Ms Ayers said that although cold temperatures, freezing fog and wintry showers are expected through the week, cloud cover could prevent some of the more extreme temperatures experienced in recent days.
She added that there is a possibility of slightly milder conditions arriving next weekend but it is too early to be certain.
The AA has advised motorists to adjust their driving to the freezing conditions on Monday morning.
Sean Sidley, AA patrol of the year, said: “On a frosty morning, hazards like black ice can prove lethal if you don’t adjust your speed and driving style in colder weather.
“Always leave plenty of space behind other vehicles as stopping distances can be 10 times longer on icy roads.
“Allow extra time, as there may be delays to your normal routes, and make sure you pack winter essentials in the car such as warm, waterproof layers, a shovel, a torch, fully charged mobile phone and a flask of hot drink.
“Take heed of warning lights in your vehicle and make sure you check it regularly if you drive less in the winter. Flat batteries are one of the top breakdowns we attend in cold weather and can be avoided by regular car maintenance.”
The recent cold snap has led to the triggering of the £25 cold weather payment to people on the lowest incomes in hundreds of affected postcode districts in England and Wales.
The Government payments are given to eligible households in areas where the average temperature has been recorded, or forecast to be, 0C or below for seven consecutive days.
