A yellow heat alert has been issued for parts of England as temperatures are forecast to hit 30C on Friday.
The alert is in place from 5pm on Friday in London, the East Midlands, the South East and eastern England and remains in place until 11pm on Saturday.
The notification, issued by the UK Health Security Agency (UKHSA) and the Met Office, highlights the risk of increased pressure on healthcare services as a result of the forecast mini-heatwave.
Temperatures could peak around 30C on Friday and Saturday in southern parts of the UK.
It will be warm at night too, with the chance temperatures won’t fall below 20C overnight.
A yellow warning is the second tier in the heat health alert service run by the UKHSA and Met Office.
The UKHSA said minor impacts on the healthcare sector are expected, with the “vulnerable population” likely to need more care.
There is also a threat of increased deaths among older and vulnerable people.

Indoor environments are also more likely to become very warm, the UKHSA said.
During a yellow warning, people can still continue with their daily routine.
The heat health alert service covers England only, with colours including green (meaning no alert is issued); yellow (meaning a response is required); amber (an enhanced response is required); and red (an emergency response) which would indicate a significant risk to life.
The hot conditions won’t last long, with rain moving through the north and west bringing cooler conditions to all parts by Sunday.
The rest of the following week is looking changeable, with temperatures around average and spells of rain moving across from the west.
