The UKHSA, a government agency for England, warned “significant impacts are likely” across health and social care services due to the high temperatures.
Parts of the country are facing a fourth heatwave of the summer, where highs pass a threshold on three consecutive days.
A yellow alert, also between 9am on Tuesday until 6pm on Wednesday, covers the North East, North West, Yorkshire, The Humber, and the South West.
Dr Paul Coleman, consultant in public health at UKHSA, said temperatures are forecast to rise above 30C (86F) across some areas which “can result in serious health outcomes” particularly for the elderly or those with serious health conditions.
“If you have friends, family or neighbours who are vulnerable, it is important to ensure they are aware of the forecasts and are following the necessary advice.
“Check in on them if you can to make sure they know that hot weather is on the way and how to keep themselves safe,” Dr Coleman said.

Sky News meteorologist Christopher England said the high pressure that brought the warmth of the last few days via the “heat dome” effect is moving east, as low pressure moves in towards the west.
“On Tuesday, southern Britain can expect temperatures widely into the low 30s… perhaps exceeding 35C (95F) in places,” he said.

Drought in England explained
On 1 July, the UK recorded its hottest day of the year so far with a temperature of 34.7C (94.4F) recorded at St James’s Park in central London.
The Met Office’s criteria for a heatwave are met when temperatures are above a certain level for three consecutive days. This threshold varies from 25C to 28C (77F to 82F) depending on the location.

Mr England added: “There’s around a 10% chance Wales may exceed its August peak temperature of 35.2C (95.3F) recorded at Hawarden on 2 August 1990.
“Expect some tropical nights too, with temperatures holding above 20C (68F).”
The UKHSA has issued advice for keeping cool: • close windows and curtains in rooms that face the sun • seek shade and cover up outside • use sunscreen, wear a hat and sunglasses • keep out of the sun at the hottest times, between 11am and 3pm • restrict physical activity to the cooler mornings or evenings • know how to respond to heat exhaustion and heatstroke
