The UK Health Security Agency (UKHSA) and the Met Office have issued an amber heat-health alert (HHA) for two further regions of England, and extended the amber alert currently in place for 5 others. A yellow HHA has been issued for the North West region.

The amber alert will cover the West Midlands and Yorkshire and the Humber regions, in addition to the East Midlands, South East, South West, London, and East of England, which have been under an amber HHA since Thursday 26 June. The amber alert will remain in place until 9am on Wednesday 2 July.

A yellow HHA has been issued for the North West, and will also be in place until 9am Wednesday 2 June.

The current hot weather is forecast to continue through Monday and Tuesday, with the potential for temperatures as high as 35 degrees Celsius (°C) in some areas. Some parts of England are also forecast to experience overnight temperatures as high as 20-22°C.

Under the Weather-Health Alert system, an amber alert means that weather impacts are likely to be felt across the whole health service. At this level, we may begin to see some health impacts across the wider population. We may also see an increase in risk to health for individuals aged over 65 years or those with pre-existing health conditions, including respiratory and cardiovascular diseases.

Dr Agostinho Sousa, Head of Extreme Events and Health Protection at UKHSA, said:

The current spell of hot weather is forecast to continue until the middle of this week, with temperatures above 30°C likely in most regions of England.

We are reminding everyone to take sensible precautions while enjoying the sun. Remember that it is very important to check on friends, family and neighbours who are more vulnerable, as the temperatures we are likely to see over the next few days can result in serious health outcomes across the population, especially for older adults or those with pre-existing health conditions.

There are additional ways in which you can keep yourself and others safe during periods of hot weather, such as:

• keeping your home cool by closing windows and curtains in rooms that face the sun
• if you do go outside, cover up with suitable clothing, such as an appropriate hat and sunglasses, and seek shade and apply sunscreen regularly
• keeping out of the sun at the hottest time of the day, between 11am and 3pm
• if you are going to do a physical activity (for example, exercising or walking the dog), plan to do these during times of the day when it is cooler, such as the morning or evening
• knowing the symptoms of heat exhaustion and heatstroke and what to do if you or someone else has them
