The county has seen its warning level increase after the UK Health Security Agency (UKHSA) originally issued a level two warning.

Level three is an amber warning and means older people, young children, and babies, as well as those with underlying health conditions, should take care.

Under the warning, the UKHSA advises people to close curtains in rooms that face the sun, drink plenty of fluid, avoid excess alcohol, and dress appropriately for the weather.

Experts have also been warning people of the dangers surrounding the hot weather.

Dr Louise Smith, Norfolk's director of public health, said: “A lot of people are really looking forward to the sunshine and warm weather, and there’s no reason not to enjoy yourself provided you take some simple steps.

"Keep out of the sun in the middle of the day, apply sunscreen and wear appropriate clothing – including a hat – and you can stay safe.

"It’s also vital to stay cool, drink plenty of water and avoid excessive alcohol or caffeine: these are simple things we all know we can do and if we make time to do them, we can safely and happily enjoy the summer weather."
