Snowy conditions described as “the first taste of winter” have caused school closures, train cancellations and road delays in parts of the UK after severe weather warnings were issued.
The Met Office put three yellow warnings for snow and ice in place in the North, the Midlands, Wales, Scotland and Northern Ireland – advising that vehicles could be stranded, power cuts may occur and rural areas could be cut off.
The yellow warning for England has been issued until 11am and the warning for Scotland will remain in place until 10am on Wednesday.
The UK Health Security Agency (UKHSA) has issued the first amber cold weather health alert of the season, warning conditions could be dangerous for vulnerable people, including the elderly.
The amber warning covers the east and north of England, the Midlands, and Yorkshire and the Humber, with yellow alerts coming into place for the South East, South West and London at 8am on Tuesday, lasting until 6pm on Saturday.
National Rail warned the cold climate would affect various routes on northern train services until at least 2pm on Tuesday.
Mersey Rail issued an alert warning passengers that due to the potential of snow and ice covering tracks, the first service on each line in north-west England would run without customers to ensure conditions could be checked.
National Highways also sent out a severe amber weather alert for snow, with the M1 in Leeds and Sheffield, the M56 in Manchester, junction 39 of the M6 and junctions 21-23 of the M62 likely to see disruption.
The Met Office, which described the conditions as “the first taste of winter”, said 5-10cm of snow would prove disruptive in England, with Derbyshire being the area most likely to be affected.
The Alzheimer’s Society warned that cold weather can be “particularly challenging” for people with dementia.
“Colder temperatures can be difficult for a person with dementia to adjust to, and they may not always be able to communicate that they are cold – or they may not even recognise it themselves,” the charity said.
It advised the public to check in on loved ones, friends and neighbours living with the condition.
Dr Agostinho Sousa, from the UKHSA, said: “This is the first amber Cold Weather Health Alert of the season, but we can expect more as we approach winter, and it is vital to check in on vulnerable friends, family and neighbours to ensure they are well prepared for the onset of cold weather.
“Particularly if they are elderly or otherwise at increased risk.”
“With high energy bills and food prices it is understandable that some may think they have to cut back on food and turn their heating off, but prolonged exposure to cold temperatures can have a serious impact on an older person’s health, especially if they are already trying to manage existing illnesses,” she said.
“The cold raises blood pressure, which in turn increases the risk of a heart attack or stroke and breathing in cold air can also increase the risk, and impact, of serious illnesses like flu and pneumonia.”
Ms Abrahams said it is “vital” that older people stay “fit, warm and well if they can” by having hot food and drinks throughout the day, wrapping up warm and sleeping with the windows closed.
Another charity Asthma + Lung UK urged those living with lung conditions to be “extra careful”.
The charity warned that cold weather can trigger potentially life-threatening asthma attacks or “flare-ups” for people with other lung conditions.
Erika Radford, head of health advice at Asthma + Lung UK, said: “Your risk of ending up in A&E doubles in winter if you have a lung condition.
“We’re here to help you to stay well, however every day people with lung conditions are needlessly suffering and without urgent action more lives will be put at risk.”
