London weather: Heathrow flights cancelled and trains disrupted as freezing fog smothers capital amid snow and ice alert

ore than flights from Heathrow were cancelled on Sunday as freezing fog descended over London - with snow and ice predicted to cause problems for Monday rush-hour travellers.

The Met Office issued a yellow fog warning for the capital on Sunday morning, which it said could cause delays to bus and train services as well as flight cancellations.

And a separate warning for snow and ice is in place for most of London and some of south-east England covering pm on Sunday to am on Monday.

A Heathrow spokesperson told the Standard: “Poor weather conditions are forecast across the UK today and we want to reassure passengers that our colleagues are working in close collaboration with our airline and air traffic control partners to get them safely away on their journeys as quickly as possible. We encourage passengers to check their flight status with their airline for the latest information.”

Elsewhere, Stansted escaped any weather-related cancellations on Sunday morning although a number of flights were delayed.

There is also major disruption to all Southern rail services running between Eastbourne and London Victoria.

The rail operator said: “Due to ice preventing trains from getting electricity from the third rail lines between Lewes and SeafordEastbourneHastings, all lines are disrupted.

Southeastern has said that ice is preventing trains from getting electricity in East Kent. No services via Dover Priory or Canterbury East are running until at least pm, they added.

Retired British Olympic rower Pete Reed OBE tweeted spectacular pictures of the blanket of fog hanging over London’s skyline as he flew in to the capital on Sunday morning.

The Met Office is predicting London will be hit with snow overnight into Monday - the first of the season in the capital - with temperatures expected to plunge to -C.

The temperature is unlikely to climb above C or C during the day on Monday and the rest of the week with overnight frosts expected.

Met Office Chief Meteorologist Steve Willington, said: “It is staying cold with daytime temperatures remaining only a few degrees above freezing in many places over the coming days and overnight temperatures dropping to -°C or lower in isolated spots.

Met Office meteorologist Rachel Ayers said: “It will continue to be a very cold day, with maximum temperatures of C to C on Sunday, and, as we head into the evening, we see persistent rain, sleet or snow in the far South East of England, which is what we have a yellow warning out for from pm on Sunday.

“We could see cm to cm of snow, perhaps up to cm in some places, with Kent and Sussex most affected, with areas most exposed such as North and South Downs and higher ground going to see the more significant accumulations.

“There will be ice forming, particularly near to the coast where there is rain and sleet, and freezing temperatures which could cause some travel disruption to start Monday with that valid until am.”

Ms Ayers said that although cold temperatures, freezing fog and wintry showers are expected through the week, cloud cover could prevent some of the more extreme temperatures experienced in recent days.

She added that there is a possibility of slightly milder conditions arriving next weekend but it is too early to be certain.

The AA has advised motorists to adjust their driving to the freezing conditions on Monday morning.

Sean Sidley, AA patrol of the year, said: “On a frosty morning, hazards like black ice can prove lethal if you don’t adjust your speed and driving style in colder weather.

“Always leave plenty of space behind other vehicles as stopping distances can be times longer on icy roads.

“Allow extra time, as there may be delays to your normal routes, and make sure you pack winter essentials in the car such as warm, waterproof layers, a shovel, a torch, fully charged mobile phone and a flask of hot drink.

“Take heed of warning lights in your vehicle and make sure you check it regularly if you drive less in the winter. Flat batteries are one of the top breakdowns we attend in cold weather and can be avoided by regular car maintenance.”

The severe conditions have been causing travel disruption with Manchester Airport temporarily closing both runways on Saturday morning due to “heavy snow”.

The RAC and North West Motorway Police both issued warnings about driving in the wintry conditions as the latter responded to traffic accidents on several major roads.

The Met Office said the conditions could lead to more travel disruption, especially on Monday morning, and a small chance of some rural communities becoming cut off along with a possibility of power cuts and mobile phone coverage being affected.

Elsewhere, the UK Health Security Agency UKHSA sent out a level three cold weather alert covering England until Friday, keeping extended the alert from Monday.

The agency is advising people to look out for friends and family who are vulnerable in the cold and to ensure they have access to warm food and drinks, adding that people should maintain indoor temperatures of at least C .F.

Dr Agostinho Sousa, consultant in public health medicine at UKHSA, said: “Cold weather can have serious consequences for health, and older people and those with heart or lung conditions can be particularly at risk.

“If you have a pre-existing medical condition, you should heat your home to a temperature that is comfortable for you.

“In rooms you mostly use such as the living room or bedroom, try to heat them to at least C if you can. Keep your bedroom windows closed at night. Wearing several layers of clothing will keep you warmer than one thicker layer.”

Darren Clark, severe weather resilience manager at National Highways, said gritters would be out to keep motorways and major A-roads open.

He said: “National Highways is committed to treating every road which needs to be treated – whenever it is needed.”
