The British Health Security Agency (UKHSA) and the Met Office have issued an amber heat-health alert for five regions of England—West Midlands, East Midlands, South East, London, and East of England—starting Tuesday, as a heatwave is expected this week. Yellow alerts remain for the North West, North East, South West, and Yorkshire and the Humber, Xinhua reported.

Temperatures are forecast to rise above 30°C, with London possibly reaching the mid-30s. The Met Office expects heatwave conditions to last several days, especially in southern and central England.

UKHSA warned the heat could impact health services and urged vulnerable groups to take precautions, according to Xinhua.
