UK cold snap: experts explain impending freeze

The UK Health Security Agency has issued an amber cold health alert for various regions as the country gets set for low temperatures. 

Cold weather experts from the University of Reading - Dr Rob Thompson and Dr Helen Hooker - explain where the chill is coming from.

Dr Helen Hooker said: “A noticeable change in our weather this week will bring cold Arctic air across all of the UK by mid-week. The Met Office has issued snow and ice warnings for northern Scotland, Northern Ireland, and central and northern England, as a low-pressure system clashes with the incoming Arctic air mass. This combination is likely to disrupt travel and transport services.

“As the cold air sinks further south, eastern areas will experience notable wind chill, making temperatures feel much colder than they are. Most of England is now under an Amber cold health alert until Saturday evening (23 November). This alert is particularly concerning for vulnerable individuals, including the elderly and those with pre-existing health conditions, who will need extra support and assistance during this period. 

“Health authorities and social care services are likely to experience increased pressures as they respond to the needs of these individuals. Communities are encouraged to check in on their neighbours and offer help wherever possible. The expected harsh weather conditions serve as a reminder of the importance of preparedness, as people are urged to stay warm, safe, and to take additional measures to protect their health during this colder spell.”

Dr Rob Thompson said: “The UK is currently entering its first cold snap of the winter as we see widespread rain in the south and snow in the north of England on Monday and Tuesday. The cold snap comes as winds start to blow from the North, a very cold direction, bringing frosts and ice to a large part of the UK. During the rest of this week, snow is expected particularly in Northern Scotland and Wales, though possible over much of the country. The transition to cold has been well forecast since last week, however, forecasts for the end of this week into the weekend are less certain with potential for snow and ice for the whole country.

“People should keep informed and ensure they are prepared for periods of icy weather, only travelling if essential. Monitor forecasts closely and ensure weather alerts are set up on your devices. Prepare your home and emergency supplies well in advance. It’s important to be stocked up on enough food and water for 3-5 days, as well as first aid supplies, essential medications, warm blankets and clothes. Why not have portable chargers and lights ready in case of power cuts? Check up on vulnerable neighbours if you can.”
