The Met Office has issued a Yellow weather warning for London, including Ealing, for overnight Sunday and Monday morning.

It said there is a risk of snow, fog and ice but suggested the chance of disruption were low.

It said: "There is a small chance of travel delays on roads with some stranded vehicles and passengers, along with delayed or cancelled rail and air travel."

A Yellow alert means there is a 'small chance' that power cuts will occur and other services, such as mobile phone coverage, may be affected

There is also a small chance of injuries from slips and falls.

Ellie Wilson, Met Office meteorologist, said: "It's looking to stay quite chilly through next week with frost overnight and some cold temperatures in the day as well.

"Through Sunday and into Monday, there's a chance the south east of England could see a little bit more in the way of snow although there's a little bit of uncertainty there."

Looking ahead, she said: "We're expecting it to last at least through next week.

"There's a chance that temperatures could fluctuate a little bit but we're not expecting them to become much milder than we've seen recently with overnight frost expected until at least next Friday, even into the weekend."

The UK Health Security Agency (UKHSA) has issued out a level three cold weather alert covering England until Friday.

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 18C (64.4F).

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 18C if you can. Keep your bedroom windows closed at night. Wearing several layers of clothing will keep you warmer than one thicker layer."
