Dense Fog Warning Issued for England, Wales, and Northern Ireland Until Monday Morning

By Elizabeth Rizzini

The Met Office has issued a yellow warning for dense fog across much of England and eastern Wales from 18:00 on Sunday until 11:00 on Monday. A separate yellow fog warning covers Northern Ireland from 22:00 on Sunday until 10:00 on Monday. The warning for England and Wales covers a large area from Canterbury to Cardiff, Hull to St Asaph, and Southampton to York, including London, Birmingham and parts of Greater Manchester. Visibility may drop below 50 metres in some places, making driving difficult. Bus, train, ferry and flight services could face delays or cancellations. The fog is expected to lift gradually through Monday morning, though some patches may linger into the afternoon. Temperatures are forecast to fall into the low single figures, and ground frost is likely in many areas. Thick fog already blanketed parts of England and Wales on Saturday night, affecting an FA Cup match between Altrincham and Notts County and causing a 30‑car pile‑up on the M20 in Kent, which left two people seriously injured, as well as a 19‑car collision on the A303 in Hampshire. Fog forms when air cools and water vapour condenses into tiny droplets near the ground. The Met Office advises drivers to check road conditions, use fog lights when visibility is seriously reduced, allow extra time for journeys and increase stopping distance. Public transport users and passengers should check for updates from their operators, as flights may be delayed due to the need for greater spacing when landing in fog.
