Thunderstorms and heavy rain to lash upon London as heatwave nears end

Wednesday, July 20, 2022

Thunderstorms and heavy showers will bring an abrupt end to the heatwave on Wednesday.

The Met Office has maintained a yellow weather warning covering much of southern and eastern England – with warnings of sudden flooding, lightning strikes and power cuts.

The warning is in place from 1pm to 9pm for much of Greater London.

Most places will experience light drizzle but there is a chance of heavy downpours and lightning.

The Met Office said that cloud will increase with a chance of scattered heavy showers or thunderstorms later inland.

A few sites could be hit with 30mm (0.8 inches) of rain in an hour and up to 50mm (2 inches) in three hours, the Met Office warned.

Temperatures are expected to plummet to between 25C on Wednesday as the scorching heatwave comes to an end.

It comes as the UK experienced its hottest day ever on Tuesday with temperatures of 40.3C in Coningsby in Lincolnshire.

The hottest temperature in London was recorded in Heathrow at 12.20pm, where the mercury reached 40.2C.

A major incident declared was declared by the London Fire Brigade on Tuesday as fires spread across the capital, with Londoners warned not to call the emergency services unless there was an immediate risk to life.
