Britons are being warned by the Met Office of a wave fog which could cover the country and cause widespread disruption to travel.
The yellow weather warning issued by the Met Office is the second of its kind this week, following a two-day risk of thick fog already causing travel bedlam between Monday and Wednesday.
Weather forecasters are now announcing that this disruption is going to last longer between today and Friday. The thick blanketing fog could bring with it plummeting temperatures below -4C.
The weather agency has also warned Britain against the extreme danger travelling of fog presents due to extremely reduced visibility.
People are being advised to completely avoid travel where it is possible. If people do find themselves out on the road, they should approach driving with major caution. Making sure to utilise their dipped headlights. Using full-beam lights in fog should be avoided as they reflect off of the fog leading to a white wall effect and great reduction of visibility.
The Met Office issued a yellow weather warning Tuesday night in relation to the fog.
The fog blanket at its most northernly point is predicted to reach towards Liverpool after is passes Birmingham and Stoke-on-Trent. In the south, it is expect to follow the south coast line before swamping coastal regions like Portsmouth and Brighton.
Explaining the warning, the Met Office wrote: “Fog patches will form during the evening and then become more widespread overnight – perhaps leading to some travel disruption.”
Forecasters are advising members of the public to expect greatly impacted journey times with delays to bus and train services very possible.
The fog also brings with it the risk of delayed or cancelled flights with airports laying in wake of the fogs path.
Airports in the affected areas include London Stansted and Birmingham International.
The fog is paired with plunging ice-cold temperatures, with forecasters calling the combination “dense freezing fog”.
The Met Office say it’s important to watch your speed as the weather form can “give the illusion of moving in slow motion”.
“It’s also important to remember to switch off fog lights after visibility improves, and to not rely on tail lights in front of your vehicle to judge your position, as they can give a false sense of security while in fog.”
The national weather agency also released warnings in regard to “freezing fog” made of water droplets that “freeze on contact with objects such as the pavement, road, car etc”. Freezing fog can form layers of ice extremely quickly.
The current path of the fog front is particularly dangerous due to the chance of widespread frost and plummeting temperatures. Some regions are predicted to hit -4C
This fog is piggybacking some already frosty conditions with up to 5cm of snow predicted to fall.
Maps from WXCharts show that the Atlantic pressure system that brought cold weather and snow from Greenland at the start of the month will continue to hit the UK, with temperatures dropping as low as -1C in parts at the start of this week.
Met Office forecaster Alex Deaking said earlier this week: “In Scotland and Northern Ireland there’s a hint of blue on the charts and so certainly in rural areas and hills there will be pockets of frost.
“Most towns and cities just about staying above but we are in the colder air here further south with the cloud and the rain we are a long way from freezing with towns in the south-west perhaps staying in double digits.”
