A red weather warning has been extended.
As of 9am yesterday, June 24, a red weather warning for extreme heat has been in force across Sussex.
The warning was set to end at 11.59pm tonight, June 25, however the Met Office has since extended this.
It announced the heat alert will now remain in place until 9pm on Friday, June 26, covering East Sussex, West Sussex and Brighton and Hove.
The UK Health Security Agency has warned "severe impacts" are expected across health and social care services due to the high temperatures.
The Met Office also advised the public to "take every effort to make precautions and adapt their daily routine".
It said: "The heatwave which is affecting a large part of England and Wales is set to continue during Friday.
"The focus of the highest temperatures on Friday is likely to shift towards east and south-eastern England, where maximum temperatures in the shade could exceed 36C, perhaps rising to 38C in some places.
"However, following another very warm night, the greatest likelihood of high impacts are expect to be within this Red warning area during Friday."
