The Met Office has issued a yellow weather warning for freezing fog covering significant areas of England, with forecasters highlighting the potential for hazardous conditions. The warning, which came into effect from late Tuesday evening and extends through to Wednesday morning, encompasses regions from the Midlands across to the East of England and parts of the South East.
Freezing fog forms when water droplets in the air remain liquid at temperatures below 0 degrees Celsius. When these droplets come into contact with surfaces, they freeze, creating a layer of ice. This phenomenon not only drastically reduces visibility, potentially to less than 100 metres in some localised areas, but also makes road surfaces slippery, increasing the risk of accidents.
Motorists are particularly urged to exercise caution during the morning commute. The Met Office has advised that journey times could be significantly longer, and there is a possibility of delays or cancellations to bus and train services. Furthermore, air travel may also be affected, with potential for flight delays or cancellations at airports within the affected regions, including London's major hubs.
Temperatures across England are expected to remain low, hovering around 0 to -3 degrees Celsius in many areas where the fog is most prevalent. This sustained cold snap exacerbates the risk of ice formation on untreated roads and pavements, posing a danger to pedestrians as well as drivers. Local authorities are likely to be on alert, with gritting operations potentially underway in an effort to mitigate the icy conditions.
While the immediate warning focuses on England, other parts of the UK are also experiencing cold weather. Scotland, Wales, and Northern Ireland are currently not under specific freezing fog warnings but are bracing for continued cold temperatures. Residents across the UK are generally advised to stay updated with the latest Met Office forecasts and local travel information, especially if planning journeys early on Wednesday.
