Thunderstorms will batter Britain tomorrow as torrential downpours look likely to cause further flooding, putting lives at risk.
The wet weather comes amid a downturn in temperatures, with things feeling a lot cooler than last week's record-breaking heat.
There was flooding in the northern areas of the UK yesterday as rainfall lashed the country.
Some 29 flood warnings, meaning flooding is expected, and 28 flood alerts, indicating likely flooding, are in force across England this morning.
Five days of thundery showers are expected in the UK this week, with temperatures averaging around the high teens and low 20s.
Met Office meteorologist Craig Snell said: "This week coming up is going to be more changeable than what we just had, with no major hot spells coming up. It is a very different flavour than last week.
"Monday will be the driest day. It will [start] off not too badly for many in England and Wales, with a good amount of sun and dry weather.
"From Tuesday onwards the rain will set in. From Tuesday to Thursday it will be a mix of sunshine and showers. Some will be heavy and thundery."
Rainfall is expected across north England and Scotland today, with some showers and potential thunderstorms in the south-west this evening.
It will be generally sunny in south, south-east, south-west and central England, with similar conditions in Wales.
A Met Office thunderstorm warning will be in force across Wales and south-west England tomorrow.
Forecasters are warning that the downpours could result in flooding, with fast flowing flood water potentially causing a danger to life.
The Met Office weather warning states: "There is a small chance of fast flowing or deep floodwater causing danger to life.
"Thunderstorms and outbreaks of heavy rain will arrive across the far southwest early on Tuesday, then spreading further northeast across England and Wales and increasing in frequency during the day.
"In a few places there is the potential for 30mm of rain to fall in an hour or two and 40 mm to fall in 3 hours. Many parts of the warning area will miss the heaviest rainfall."
The alert said homes and businesses could be flooded, with storms potentially causing damage to properties.
It added that flooding may lead to power cuts and delays for drivers and public transport users.
The Met Office weather map shows that thunderstorms may also strike in south-west, central, north and north-west England tomorrow.
