UK heat health alert issued this week - Full list of regions as temperatures to hit 30C The high temperatures will bring 'muggy' conditions, leading to 'quite uncomfortable' nights for sleeping Temperatures are set to rise across various regions in the UK as scorching temperatures are once again set to take over. After a period of milder and rainy weather, summer temperatures are due to return this weekend, bringing highs of up to 30C. The UK Health Security Agency (UKHSA) has warned of "greater risk to life of vulnerable people" as a new yellow heat health alert will come into force. The warning is in place from 3pm on Wednesday, June 17, until 8pm on Monday, June 22, with other impacts including increased use of healthcare services by vulnerable people, indoor environments becoming very warm, as an increased risk of water-related incidents. The alert will cover London, South East, East of England and the East Midlands, the UKHSA said. The Met Office has warned temperatures in the South East could reach heatwave criteria by the weekend. "Friday is likely to see very warm, locally hot conditions for south-east and some eastern areas of England, with higher humidity and the chance of a few thunderstorms," a spokesperson for UKHSA said on Monday, June 15. "There is considerable uncertainty for the duration of the very warm conditions however, as a weak weather front moving east into Saturday may bring slightly lower temperatures and fresher conditions. "However, there is the potential that the weather front stalls toward the South East allowing very warm or hot conditions to linger across, or near to the far south or South East, perhaps then becoming more extensive again into the following week." Jonathan Vautrey, meteorologist at the Met Office, warned rising temperatures and humidity will likely come with overcast skies for many. "By Friday there is potential for 30C across parts of south-eastern England,” Mr Vautrey said. He continued: "The exact detail of the temperatures is going to be dependent on cloud amounts, because, whilst it is going to be warmer this coming week, there’s actually going to be a reasonable amount of cloud around at times as well – so it’s not going to be sort of wall to wall sunshine every day. "But those temperatures are going to be rising nonetheless and, with that, it’s also going to be increasingly humid this time around. "So I think people will certainly be noticing how muggy it starts to feel during the second half of this weekend, and some quite uncomfortable nights for sleeping well, with overnight temperatures in the high teens across south-eastern areas of England." The West Midlands, parts of the West Country and areas of Wales are likely to experience warm temperatures around the mid-teens by the end of the week, Mr Vautrey added. Scotland and Northern Ireland, however, are expected to see more cloudy weather and rain over the course of the week, with temperatures in those parts of the UK unlikely to rise above 20C to 21C.
