Cold-health alerts for North East, North West and Yorkshire run from Sunday night to Thursday
The yellow alerts start at 9pm on Sunday 15 November and last until 9am on Thursday 19 November, after a milder, wet Sunday.
Three English regions will be under yellow cold-health alerts from 9pm on Sunday 15 November until 9am on Thursday 19 November, the UK Health Security Agency (UKHSA) said on Saturday.
The alerts cover the North East, the North West, and Yorkshire and the Humber. No other region of England has one.
It is the second round of alerts this winter. The first, for the North West and West Midlands, ran from Thursday morning until midday on Saturday.
A yellow alert means the cold is unlikely to affect most people but could harm those who are particularly vulnerable. UKHSA names people aged 65 and over, people with existing health conditions such as heart and lung disease, and people sleeping rough. Health and care services also tend to get busier in cold spells.
The agency's advice for households is to heat the rooms you spend most time in, such as the living room or bedroom, to dress warmly, and to check on friends, relatives and neighbours who are most at risk. It said more alerts are likely as winter goes on.
Sunday should be milder after Saturday's sharp frost, BBC Weather said, with temperatures of around 2C to 6C first thing in most places and rain spreading across much of the UK. Thundery downpours are possible in the south, and fallen leaves blocking drains could cause local flooding.
Colder air returns from the north on Monday, bringing frost and fog back. Afternoon highs will be around 5C to 8C in most places, with a wind chill near eastern coasts.
