Britain last night fell victim to its coldest night of the year so far, with much of the UK expected to face a week of snow flurries and icy conditions in the coming days.
How cold is it where you are?
The Highlands saw temperatures fall to at least minus 11C overnight and forecasters now warn that there's not yet to be any respite to the conditions.
A fine blanket of snow covered areas such as Epson Downs in Surrey, and an amber weather warning has been issues for icy conditions across England in areas including the North, East Anglia and Midlands, until midday on Thursday.
"Large areas of England will experience colder than average conditions in the coming week, with widespread overnight frosts. Some wintry precipitation is expected for most areas too, mostly in the form of scattered showers, leading to lying snow and icy stretches." read an alert.
A van had overturned and seven vehicles slid from the road on the A24 in West Sussex early this morning, which saw the road closed down for over an hour.
Two men suffered arm and facial injuries in the event and were taken by ambulance to hospital.
Further chaos ensued near Oxford on the A34 when a car transport skidded off the road, going "through the central reservation and into a ditch."
A spokesman for Thames Valley Police said that the "road is likely to remain closed throughout the morning rush hour period."
The accident block the southbound carriageway between the A4130 Milton Interchage and the A4185 Chilton Interchage, with police also closing one of the two northbound lanes.
Delays at Manchester Airport have also been caused because of freezing and foggy conditions with at least two flights diverted elsewhere.
Meanwhile, a forecaster at MeteoGroup, Tom Tobler warned of a weather front which could see snow hit hard Tuesday or Wednesday.
"It's going to be very cold again tonight, certainly below zero pretty much everywhere. Temperatures could be minus 3C or 4C in England and Wales and in Scotland we could see minus 10C.
"There's a front coming through Tuesday and Wednesday which might bring some snow, mostly in northern parts of the country. Parts of England could get snow but it won't be huge amounts."
Motorists are now being advised to pack emergency bags including food, a hot drink, a torch, warm clothes and blankets as well as a charged mobile phone and first aid kit.
Public Health England has also urged civilians to look after their elderly friends, neighbours and relatives as Age UK warned one older person could die every seven minutes from the cold this winter.
Director for the charity Caroline Abrahams said: "The cold weather can be particularly dangerous for older people who are more at risk of suffering health problems when the temperature drops.
"It's a shocking fact that this winter one older person could die every seven minutes from the cold.
"With just under one million older people living in fuel poverty, many simply cannot afford to heat their homes to a temperature high enough to keep well and warm.
"We are calling for the Government to commit to improving the energy efficiency of homes across the country in order to provide a long-lasting solution to the scandal of fuel poverty and preventable winter deaths."
