Temperatures in Britain are expected to surpass 40 C (104 F) for the first time ever on Tuesday, after going through the warmest night on record Monday night.

The Met Office provisionally reported Monday night as the warmest ever as temperatures did not fall below 25 C in some places.

The previous highest daily minimum was 23.9 C on Aug 3, 1990. In parts of Yorkshire and London, temperatures of 26 C were recorded.

The Met Office issued its first-ever red warning for large swathes of England due to the scorching heatwave.

The heatwave is having an impact on transport and infrastructure, with trains being canceled and routes being closed.

On Monday, Luton Airport suspended flights due to high temperatures causing a defect in the runway.

Temperatures are expected to be even higher today and predicted to surpass 40 C.

Rachel Ayers, a Met Office forecaster, was quoted by local media as saying that Tuesday will be “a pretty unprecedented day.”
