Amber and yellow heat-health alerts are in place across England as very hot weather is forecast.

BBC Weather says: "Temperatures could rise as high as 36C (97F) for parts of southern England this week." That is much hotter than a normal UK summer day.

In the UK, a heatwave happens when a place is hotter than usual for at least three days in a row.

The temperature needed for a heatwave is not the same everywhere. Southern England usually has warmer weather, so the heatwave temperature there is higher. Cooler parts of the UK, such as Scotland or northern England, can meet heatwave conditions at a lower temperature.

BBC Weather says the hottest places are expected to be in southern England, while northern areas may be cooler, with temperatures in the mid-20s Celsius. The heat is forecast to be at it's hottest on Friday.

A heat-health alert is a warning used in England to help hospitals, care homes, councils and the public prepare when heat could harm people's health. It is run by the UK Health Security Agency and the Met Office.

What are the heat-health alert colours and what do they mean?

  • Yellow means the heat is unlikely to impact most people, however some, especially older people or those with health problems, may struggle. Health and care services need to be prepared.

  • Amber is more serious. It means the heat could affect the wider health service and more people, not just those already at risk.

  • Red is the highest level. It means there is a serious risk, even for healthy people.

How hot will it get?

Amber alerts cover the Midlands, eastern and southern England until 9pm on Sunday 12 July. Yellow alerts are in place across northern England for the same period.

BBC Weather says: "Parts of the south and east officially entered a heatwave on Monday, after three days at or above their threshold temperatures.

"More locations could reach 34C or 35C in the coming days, with the hot spot likely to be in southern England.

"Heat will continue to build and extend north and west into Northern Ireland and Scotland until Friday. Where the peak is expected in the high 20s Celsius."
