Forecasters warn a month’s worth of rain could pour today after thunderstorms caused wide-spread disruption on Saturday, with flooded roads and railway lines in the south of England.
The Met Office previously issued a yellow warning for thunderstorms across much of England and Wales, stretching across the weekend and into most of Monday.
Heavy rain hit parts of the south of England on Saturday, with 24.1 mm of rain falling in just an hour in Canterbury, Kent.
Downpours caused disruption, with floods affecting businesses and many forms of transport.
And the deluge is only set to continue with up to 3.5ins predicted to fall on Sunday.
In Bishop’s Stortford, Hertfordshire, the county’s Fire and Rescue Service were called to rescue two people and a dog after the car they were in became stuck in floodwater.
Floods also hit Essex on Saturday, with the heavy rain affecting many roads.
Greater Anglia trains said heavy rain flooding the railway, and debris, had delayed and cancelled trains between Colchester, also in Essex, and Marks Tey stations for several hours.
The Met Office said Writtle, a mile from Chelmsford, had 52.8 mm of rainfall in a 12-hour period.

Heavy rain with the risk of thunderstorms is expected to continue over the rest of the weekend, with warnings of potential flooding and travel disruption.
Bad weather including rain and low cloud caused the cancellation of three commemorative flypasts by the Red Arrows on Saturday.
The RAF display team had planned to fly over London, Cardiff, Edinburgh and Belfast to commemorate 75 years since VJ Day. However, only the Belfast flypast took place.
Meteorologist Matthew Box said Saturday’s stormy weather broke out in Kent before moving across Essex, where some places saw 40 mm of rain in around 40 minutes.
‘It may not mean anything to a non-meteorologist maybe but that is a healthy dose of rain in under an hour,’ he said.
Mr Box said Sunday was likely to bring large hail and gusty winds as well as rainfall of up to 90 mm in places hit by multiple thunderstorms.
He said: ‘We’re going to see essentially some pulses of potentially thundery showers pushing their way up from the channel through the course of the morning affecting southern counties.
‘In the afternoon we’ll see some home-grown showers develop across the southern half of England and then they’re all going to drift gradually northward.’

Warning of the risk of more flooding, he added: ‘Where the showers do form there’s certainly the potential for 30 to 40 mm of rainfall within the hour.
‘Some places that get hit by a few thunderstorms maybe even see 60 to 90 mm of water in a couple of hours – that is a lot of water to fall in one spot, nearly 10 cm of rain.
‘It’s going to be a lively day on Sunday, or it’s got the potential to be.’
In the areas not hit by rain, forecasters expect the rest of the weekend to be much cooler after a week of hot and humid weather.
The Lake District town of Keswick in Cumbria saw the mercury rise to 24.8C on Saturday.
However, this was milder than much of the week, where temperatures above 34C were recorded for six days in a row.
The Met Office said 24.1mm of rain fell in an hour in Canterbury, Kent, on Saturday, which could lead to some surface flooding.
Becky Mitchell, a meteorologist for the Met Office, said the weekend was a ‘messy picture’.
She added: ‘The main thing over the next three days is the risk of thunderstorms in the south.
‘Saturday night is going to be pretty mild and then Sunday across the south it’s a picture of sunshine and showers – those showers could be thundery at times.
‘That risk is really within the warning zone – central and southern England and Wales could see some heavy downpours tomorrow.
‘Further north it’s going to be a bit drier with cloudy skies across the east coast.’

The Met Office has issued a yellow thunderstorm warning for vast swathes of England and Wales on both Saturday and Sunday – just as thousands of holidaymakers rushed back from France after the country was added to the UK’s quarantine list
Bad weather including heavy rain and low cloud caused the cancellation of three commemorative flypasts by the Red Arrows.
The RAF display team had planned to fly over London, Cardiff, Edinburgh and Belfast to commemorate 75 years since VJ Day.

The Lake District town of Keswick in Cumbria saw the mercury rise to 24.8C on Saturday.
However, this was milder than much of the week, where temperatures above 34C (93.2F) were recorded for six days in a row.
The south of England and Wales are likely to be the wettest areas, with frequent lightning, gusty winds and heavy downpours with 30 to 40mm of rain possible in less than an hour, according to the Met Office.
Five flood alert warnings have been issued across the West Midlands by the Environment Agency.
Met Office chief meteorologist Frank Saunders said: ‘Up until Monday, thunderstorm warnings cover much of England and Wales, with parts of southern England and South Wales seeing the greatest likelihood of impacts.
‘The storms will not affect all areas, but where they happen there will be frequent lightning, gusty winds and intense, heavy downpours with 30 to 40 millimetres of rain possible in less than an hour and, in a few unlucky spots, a small chance of 60 mm falling in a short period.
The poor weather is only set to continue with flooding (pictured) potentially leading to road closures, while extreme weather may damage buildings and cause power cuts and cancellations to train and bus services

‘With the continuing hot weather, large swathes of the UK continue to be at risk from thunderstorms, and potentially the impacts from heavy rain, into the early part of next week.’
Spokesman Oli Claydon, added: ‘The overnight temperatures remaining quite high will mean quite a close, muggy feeling that is in tune with thunderstorms being forecast all the way through to Monday.
‘Some areas could see up as much as 40-50mm (1½-2in) of rain in two to three hours [today], with 50-70mm (2-2½in) possible in three hours on Sunday.
‘There’s continued thunderstorm warnings through to Monday at the moment.’
Saturday’s outlook should be bright in the West but with thick cloud coming in from the North Sea in the North East, the Met Office said.
Mr Claydon added: ‘One thing to note with this kind of weather is it is important to keep an eye on the forecast as it can change quite quickly.
‘The nature of thunderstorms means it is quite tricky to be more specific as to exactly where. We can expect them anywhere in those yellow warning areas.’
Neil Davies, Flood Duty Manager at the Environment Agency, said: ‘Isolated thunderstorms could bring sudden surface water and river flooding, which may lead to flooded properties and severe travel disruption in some areas. Further surface water and river flooding is also a possibility until Sunday.’
The weather will be an added kick in the teeth for the thousands of Britons who made a mad dash across the Channel last night in a desperate bid to make it home before the government’s 14-day quarantine kicked in at 4am.

From 4am onwards, all those arriving from France must quarantine for 14 days after the country reported a spike in coronavirus cases.
The 11th-hour move sparked chaos for an estimated 500,000 British holidaymakers in France – including a couple who forked out £1,000 for business class Eurostar seats and a family who drove for 12 hours to get home.
One mother was forced to leave two of her children behind with her husband when she fled France on the last Eurostar train.
The woman – who had to return to the UK before quarantine began due to her job – was only able to get tickets for herself and her baby.
She now fears her two daughters – who will return on Monday – may not be out of quarantine when their school goes back.
The woman, who did not provide her name, told Sky News: ‘This has completely ruined our summer. I don’t know what I’m going to do now. I am so upset about this.’
There are also fears that the new rules will cause thousands of children to miss the start of the school year as pupils who do not return to the UK by Tuesday night will still be self-isolating at home when the majority of schools go back on September 2.
But with limited capacity on flights, ferries and the Eurotunnel, many will have no choice but to stay in France – or pay high prices for some of the remaining tickets.
Some tourists had less time to avoid quarantine after the Scottish and Welsh governments demanded the rules be introduced a day earlier.
Meanwhile, France is likely to impose to impose tit-for-tat quarantine restrictions from Monday for people arriving from Britain, meaning British travellers will have to self-isolate on arrival there too.
