A yellow heat health alert has come into force across parts of the UK despite forecasts of rain this weekend.
The warnings are in place from 9am on Friday to 9am on Sunday, and covers the East Midlands, West Midlands, South East, South West, the east of England and London.
The UK Health Security Agency (UKHSA) said the hot weather could have an impact across health and social care services and put vulnerable people at risk.
Health chiefs also warned water‑related incidents may increase, including risks from cold‑water shock and drowning.
Temperatures are set to hit 29C on Saturday in London and 28C in Birmingham and Norwich. But rain is also forecast.
It comes after three consecutive heatwaves and one of the driest springs on record with hosepipe bans in place across the country.
