Fog could limit visibility to just 100 metres with the worst forecast to descend on South East and central England

Fog has caused significant disruption at major airports across the UK, including London Gatwick, Heathrow, and Manchester, leading to delays and cancellations. The widespread fog, which has affected much of the country in recent days, is complicating travel plans as airports work to return to normal operations after the Christmas holiday rush.

Tens of thousands of airline passengers endured long delays, diversions and cancellations as low cloud and fog blanketed southeast England – which has the busiest skies in the world.The Independent has calculated that more than 200 flights to and from UK airports were cancelled between noon on Friday and Saturday evening as air traffic controllers slowed the “flow rate” at both London Heathrow and Gatwick.
