Brits are set to swelter in 34C heat as forecasters predict tomorrow will be the hottest day of the year.deckchSoaring temperatures have sparked a heat health alert from the Met Office and Public Health England, as they warn elderly and vulnerable people to take extra care. The mercury will soar into the 30Cs today before possibly hitting 34C (93.2F) over the next 48 hours.

Forecasters say while much of the country will swelter into the weekend and the soaring temperatures are likely to beat the current hottest day of the year, which stands at 33.5C (92.3F) recorded at Brize Norton, Oxfordshire, last month. Health experts have warned people to take extra care over the next few days as thermometers rocket.

Dr Angie Bone, head of extreme events at Public Health England (PHE) said: “Much of the advice on beating the heat is common sense and for most people there’s nothing to really worry about. ┬áBut for some people, such as older people, those with underlying health conditions and those with young children, summer heat can bring real health risks.

“The forecast suggests we may be in for some hot days and uncomfortable nights too so now’s the time to think about how’s best to keep cool and safe.”
