Met Office extends amber warning for Cambridgeshire for 'final hot and humid night'

The Met Office has extended its amber weather warning for extreme heat, now running until 9am on Sunday morning, June 28. The alert covers Cambridgeshire and surrounding areas including Essex, Hertfordshire, central Bedfordshire, Lincolnshire, West Sussex, and parts of the East Midlands, East of England, London and South East England.

Hot and humid conditions are forecast to continue across parts of east and south-east England. While temperatures are expected to be a few degrees cooler than recent days, they will still widely exceed 30C, peaking around 32 to 33C in East Anglia. The extension caters for what officials describe as the final hot and humid night of the departing heatwave.

Overnight temperatures from Saturday into Sunday are unlikely to fall below the high teens Celsius for most areas, with a few places not dropping below 20C. High humidity will accompany these conditions initially, though fresher conditions are expected to become established from the west during the latter part of the night. On Sunday, another hot day is anticipated in the far east of the region, but both temperatures and humidity will be lower than recent days with a much lower likelihood of further impacts.

Britain has experienced scorching temperatures in recent days, with the UK provisionally breaking its temperature record for a third consecutive day on Friday, June 26, when the mercury hit 37.3C at Santon Downham in Suffolk. This surpassed the previous record of 35.6C, which was set in 1957 and 1976.

The extended warning comes as the Met Office has also issued yellow thunderstorm warnings for this evening due to Saturday's heat and humidity. Developing thunderstorms may cause brief periods of frequent strong gusty winds, large hail and heavy rain in affected areas, with potential for disruption to transport services and slight risk of flooding and power loss to homes and businesses.
