Good news for those travelling home from England for Christmas as fog lifts from main airports
Passengers travelling from England's main airports escaped delays and cancellations on Monday morning after a blanket of fog over southern and central parts of the country began to lift.
There were fears that flights might be badly hit after the Met Office issued a severe weather warning for fog for a large swathe of land stretching from the South Coast to the Vale of York and East Anglia.
But forecasters said the fog had eased overnight to a lighter mist in some areas and would continue to break up throughout the day.
Both Heathrow and Gatwick Airports warned passengers on their websites of delays and cancellations overnight, but by Monday morning Gatwick said "reasonable" visibility meant there was no impact on flights, while Heathrow was a little misty with just a few knock-on effects from delays at the weekend.
A Heathrow spokesman said: "Our advice to passengers is to check with airlines before coming to the airport. We will be reviewing the fog warning in the next few hours."
Met Office forecaster Chris Page said visibility at both airports was above 1,000m (3,281ft) - below which is regarded as foggy - and that it was overcast and cloudy in both areas.
But he warned that drivers on the M4 could experience dense fog patches, as visibility at weather stations near the motorway was down to between 200m and 300m (220-330 yards).
Mr Page said: "There is quite a lot of fog in the southern counties of England, in East Anglia and the Midlands.
"The weather warning is valid until 10 o'clock this morning. The majority of the fog will be clear by then but it may linger in places maybe until midday, and will be patchy.
"It will lift and break up through the day but some places may hold on to the fog until this afternoon.
"There will also be a little bit of rain this morning, pushing its way up from the Continent, along with another band coming from the North West, squeezing into the middle of the UK and helping to break and lift the fog."
