Heat health warnings are in place across all of England, as forecasts of a record-breaking bank holiday heatwave pose a threat to life, particularly among the elderly and unwell.

Highs of 33°C are forecast in southern England and the Midlands over the long weekend, with the Met Office expecting May and spring temperature records to be broken.

Friday is the hottest day of the year so far as temperatures reached 26.9°C in Heathrow, west London, in the early afternoon, the Met Office said.

The “extraordinary” warnings include upgraded amber alerts covering the middle and south-east of England, and are in effect from 2pm on Friday, 22 May to 5pm on Wednesday, 27 May.
