An amber “cold health alert” has been issued for the whole county, with warnings of an increase in deaths among the elderly and extra demand on hospitals.

The Met Office and the government upped their warning from yellow to the more serious rating today.

It covers the whole of the UK, with temperatures set to drop to as low as -4°C in Kent.

The alert is in place from today until Wednesday, January 8.

Temperatures inthe county are set to hit lows of -4°C tomorrow morning, with a ‘feels like’ forecast of -7°C.

There is also a weather warning for snow and ice for Saturday and Sunday.

It covers most of the county, with the exception of Romney Marsh, part of the Canterbury district, Thanet, Dover and the east of the Isle of Sheppey.

However, forecasters predict more sleet for southern England as opposed to heavy snow.

The Met Office says the low temperatures are likely to cause a significant impact across health and social care services.

A spokesman added: “There could be a rise in deaths, particularly among those aged 65 and over or with health conditions. We may also see impacts on younger age groups

“There will be a likely increase in demand for health services

“Temperatures inside places like hospitals, care homes, and clinics may drop below the levels recommended for assessing health risks.

“There may be challenges keeping indoor temperatures at the recommended 18°C, leading to more risk to vulnerable people.”

Kate Langford, chief medical officer at NHS Kent and Medway, is urging people to keep an eye out for family members, friends and neighbours who might be vulnerable.

“Prolonged cold weather can be a risk for anyone, but those who are vulnerable, including elderly people, those with breathing difficulties, and children under five, are particularly at risk,” she said.
