Met Office issues new thunderstorm warning as Brits face MORE flash flooding

Brits should brace for more weather chaos as thunderstorms and lightning are expected to cause damage later today.

After stormy weather began drenching the British Isles last weekend, many had thought there would be a return to drier conditions this week.

However, the Met Office has now issued a yellow weather warning for thunderstorms in London and the south east today.

The main areas affected are Brighton and Hove, East Sussex, and Kent, the forecaster adds.

The stormy weather could see as much as 20-25mm of rain dumped on these areas in less than an hours. In a few locations, there could be as much as 30 to 40mm in one to two hours.

With this amount of water, surface flooding and disruption is likely, and lightning strikes could be an additional hazard, the forecaster said.

"Showers and thunderstorms will slowly die out during Wednesday evening", the warnings reads.

It comes after the Met Office revealed when warm conditions would return to the UK.

Forecasters have said westerly winds and showers will dominate the end of July, but things are set to change in August. As we get into next month, temperatures could be near or above average, the Met Office said, with some "very warm or hot spells" developing. The national forecaster said these spells are especially likely in the "south and east".

Currently, weather maps show temperatures rising in England and Wales at the start of next month - with highs of 31C possible in southern and south-eastern England on August 6. Warm conditions could also return later in the month, according to the Met Office.

The Met Office's long-range weather forecast from August 6 to August 20 states: "A changeable westerly pattern will likely continue through into the start of August, with spells of rain or showers mixed in with some drier, brighter days. There are signs that high pressure to the southwest may try to extend its influence across the UK, which could bring more in the way of dry, settled weather as we head further into August.

"Temperatures will likely continue to be near or above average overall. There is a chance of some very warm or hot spells developing later in August if high pressure wins out for a decent stretch of time, especially in the south and east."
