Large swathes of the country are at risk of further thunderstorms and torrential downpours with a threat of more unsettled weather to come.
A yellow thunderstorm warning covering the whole of Wales, southern England and parts of the north is due to expire at 9pm on Monday following days of unsettled weather conditions - and there could be a sting in the tail of the miserable spell.
The Met Office has warned of potential further heavy rain, which could see up to 1.6in (40mm) falling within in an hour in some areas.
“If you’re caught by a thunderstorm, you’re likely to see 20mm-40mm (0.8in-1.6in) of rain within the hour, and some areas could see 50mm-70mm (2in-2.8in) within three to four hours,” according to Nicola Maxey, a spokeswoman for the Met Office.
“Really, anywhere within the warning area is at risk of those storms.”
The Environment Agency has issued a number of flood alerts for parts of the Midlands around Birmingham.
A further yellow thunderstorm warning has been issued covering a large area of Scotland for Tuesday afternoon.
Heavy showers could lead to properties being flooded, while there is a chance roads could be closed due to rain lashing the area, the Met Office said.
Sunshine and showers are expected across the UK during an unsettled week but rainfall will be more sustained, with the potential for 0.8in (20mm) falling over six hours.
Temperatures are closer to average compared with last week’s scorching conditions, with south-east England “significantly cooler,” according the Met Office forecaster.
“As we go through the week, we’re looking at those mid-20s for the south-east and, as we go further north, towards Manchester, it will be 22C, 23C, so the low 20s the further north you go,” she said.
“This is closer to average as we’re heading towards autumn, so not that unusual.”
