THUNDERSTORMS are set to batter the UK this week and spark more life-threatening floods, the Met Office has warned.
The forecaster has issued a yellow “severe” weather warning for thunderstorms across the South West and Wales for Tuesday.
After an extremely wet weekend saw flooding hit some areas, much of the country will experience a warm, dry day with plenty of sunshine today.
But the South West from Cornwall to Dorset will get a taste of things to come with rain, thunderstorms and 40mph winds as an area of low pressure barrels towards Britain today.
By tomorrow, the weather system will blanket almost the entire country in rain – with some areas being inundated with half a month’s rain in an hour.
Weather forecasters fear the predicted floods, lightning, hail and strong winds could spark travel chaos.
The Met Office warned train and bus services may be delayed or cancelled, driving conditions will be difficult and roads could be closed due to flooding.
The thunderstorms and heavy rain may also spark blackouts.
In its severe weather warning, the Met Office said: “There is a small chance of fast flowing or deep floodwater causing danger to life.”
Just before 1am on Monday, the Environment Agency advised the Greater Manchester region had 17 flood warnings in place, meaning immediate action was required.
There were also 11 flood alerts – meaning be prepared – in place for the region after torrential rain.
Weather forecasters said while the heavy rain will clear on Monday, a second band of low pressure will hit the country on Tuesday.
There’s definitely a risk of flooding
Met Office forecaster Mark Wilson
Met Office meteorologist Mark Wilson said parts of the South West and Wales will see heavy downpours and could get between 30mm and 40mm of rain.
The average rainfall for the region in July is 81mm, he added.
Mr Wilson said: “An area of low pressure will bring the risk of quite heavy thundery showers into Tuesday.
“There’s definitely a risk of flooding.
“Thunderstorms are a concern – there could be as much as 30mm to 40mm of rain. That’s quite a lot of rain flowing in quite a short period of time.”
The new weather warning follows a weekend of heavy downpours with half a month’s worth of rain falling across parts of the UK leading to travel disruption and floods.
A yellow weather warning for rain was in place across parts of the Midlands, the North West of England, Northern Ireland and south-west Scotland on Sunday.
Forecasters said that parts of the North West had seen 40mm to 50mm of rain in about 24 hours, with 52.2mm recorded between 11am on Saturday and 11am on Sunday at Greenfield near Oldham.
The Met office said that the monthly average rainfall for the North West in July was 89.5mm.

The Environment Agency had issued 30 flood warnings on Sunday evening, the majority in the North West region, and urged people to avoid swollen rivers and not to drive through flood water.
Parts of the North West were hit with floods with cars left almost fully submerged.
The wet weather comes after a week in which Britain was hit by hot temperatures and thunderstorms, with the heatwave causing problems for train and air passengers.
