Thunderstorms are expected in much of the UK after flash flooding left parts of a Welsh town under water.
Isolated flooding is possible across parts of England over the next few days due to heavy storms, the Environment Agency has warned.
On Monday storms brought flash flooding and power cuts to Aberystwyth, in west Wales.
Councillor Ceredig Davies said the area hadn’t seen a downpour like it in years.
“There are a number of properties in town that have flooded towards the lower part of the town - and a number of high street shops have had water coming through,” he told WalesOnline.
“It was such a downpour.”
Thunderstorms are set to strike this week with most of the UK covered by a Met Office yellow warning until Thursday.
The Met Office has warned flash flooding could cause travel disruption and power cuts.
There is also a small chance homes and businesses could be damaged by flooding.
Bonnie Diamond, a meteorologist at the Met Office, said: “There is a pretty broad warning in place today, but there is another for central UK – the Midlands up to the North West of England to about Cumbria, and into Wales – which we are watching really closely.
“We are looking at the potential for some thunderstorms there from about 4pm to the early hours.
“It’s a worst-case scenario - a caution, really, for what could happen - but we are looking at a potential for 150mm of rain in three or four hours.
“Normally for August you’re looking at around 70mm for the month, so it’s potentially a lot of rain.
“To get that much it will take some areas seeing frequent thunderstorms, and not just passing through.”
Caroline Douglass, flood duty manager at the Environment Agency, said heavy thunderstorms this week “could lead to surface water and river flooding in some communities” into Tuesday morning.
“Isolated flooding is also possible more widely across England today through until Thursday due to further heavy thunderstorms,” she said.
“Severe thunderstorms” are expected for the next few days, following a series of scorching days that saw temperatures reach the 30Cs.
