Fog expected to disrupt transport across southern England, Wales and Northern Ireland early week
Meteorologists warn that thick fog will affect visibility and cause delays to road, rail and air travel in parts of the UK from Monday, with yellow weather warnings issued.
Thick fog is forecast to cover much of southern England, eastern Wales and most of Northern Ireland during the early part of the week, prompting transport operators to warn of possible delays. The Met Office issued yellow weather warnings for the affected regions, indicating visibility could fall to 50 metres or less and that bus, train and flight services may be disrupted.
Niamh Murray, a Met Office operational meteorologist, explained that the combination of clear skies, light winds and long autumn nights creates conditions conducive to fog formation.
Heathrow Airport advised passengers that reduced visibility around the airport could continue into Monday morning and urged travellers to allow extra time, check with airlines and drive cautiously.
A 30-vehicle collision in fog on Saturday on the M20 near Maidstone resulted in two serious injuries and temporary road closure.
Edmund King, president of the AA, reminded drivers that fog can quickly reduce sightlines and recommended reducing speed, increasing following distances and allowing extra travel time.
