Forecasters warn that there could be a month of rain today after thunderstorms on Saturday caused widespread disruption to flooded roads and railroad lines in the south of England.
The Met Office previously issued a yellow warning for thunderstorms across much of England and Wales that stretched over the weekend through most of Monday.
Heavy rain hit parts of the south of England on Saturday. In just one hour, Canterbury, Kent fell 24.1 mm of rain.
Downpours caused disruption, with flooding affecting businesses and many modes of transport.
And the deluge is only going to last up to 3.5 inches, which is expected to fall on Sunday.
In Bishop & # 39; s Stortford, Hertfordshire, the county Fire and Rescue Service was called upon to rescue two people and a dog after the car they were in got stuck in the flood.
There was also flooding in Essex on Saturday. Many streets were hit by heavy rain.
Trains from the greater Anglia area said heavy rain that flooded the railroad and debris delayed and canceled trains between Colchester stations, also in Essex, and Marks Tey for several hours.
The Met Office said Writtle, a mile from Chelmsford, had 52.8mm of precipitation in 12 hours.

Bad weather, including rain and low clouds, resulted in the Red Arrows canceling three commemorative flies 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 over Essex, where in some places 40mm of rain fell in about 40 minutes.
"It might not mean anything to a non-meteorologist, but that's a healthy dose of rain in less than an hour," he said.
Mr Box said Sunday would likely bring major hail and gusty winds, as well as rainfall of up to 90mm in places hit by multiple thunderstorms.
He said, “We are essentially going to see some pulse of possible thunderstorm rain pushing up from the canal later this morning affecting the southern counties.
"In the afternoon some home-grown showers will develop in the southern half of England and then they will all gradually drift north."
A woman is rescued from floods in Bishop & # 39; s Stortford. Several streets in Bishop & # 39; s Stortford are flooding again today. The heavy rain soaked Hertfordshire again this morning, which has resulted in many streets being flooded.

He warned of the risk of further flooding, adding: “Where the showers form, 30 to 40 mm of precipitation can fall in an hour.
“Some places that are hit by a few thunderstorms may even see 60 to 90 mm of water in a few hours – that's a lot of water to fall in one place, almost 10 cm of rain.
"It's going to be a busy Sunday or it has the potential to be."
In areas unaffected by the rain, forecasters expect the rest of the weekend to be much cooler after a week of hot and humid weather.
In the town of Keswick in the Lake District, Cumbria, mercury rose to 24.8 ° C on Saturday.
However, this was milder than much of the week in which temperatures above 34 ° C were recorded for six days in a row.
The Met Office said it fell 24.1mm of rain in one hour in Canterbury, Kent on Saturday, which could cause flooding on the surface.
Becky Mitchell, a Met Office meteorologist, said the weekend was a "chaotic picture".
She added: “The main thing over the next three days is the risk of thunderstorms in the south.
“Saturday night gets pretty mild and on Sunday in the south it's a picture of sunshine and showers – those showers can thunder at times.
& # 39; That risk is really in the warning zone – central and southern England and Wales could experience heavy downpours tomorrow.
"Further north it gets a bit drier with cloudy skies on the east coast."

Bad weather, including heavy rainfall and low clouds, resulted in the Red Arrows canceling three commemorative flies.
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 as the other events were canceled due to bad weather.
In addition to the rain, forecasters expect the rest of the weekend to be much cooler after a week of hot and humid weather.
In the town of Keswick in the Lake District, Cumbria, mercury rose to 24.8 ° C on Saturday.
However, this was milder than much of the week that saw temperatures above 34 ° C (93.2 ° F) for six days in a row.
The south of England and Wales are probably the wettest areas, according to the Met Office, with frequent lightning, gusty winds and heavy rainfall with 30-40mm of rain possible in less than an hour.
The Environment Agency has issued five flood warnings in the West Midlands.
Frank Saunders, the Met Office's chief meteorologist, said: “As of Monday, thunderstorm warnings will cover much of England and Wales, with parts of southern England and South Wales seeing the greatest likelihood of impact.
“The storms won't affect all areas, but where they do happen there are frequent lightning strikes, gusty winds and intense, heavy downpours with 30 to 40 millimeters of rain that can be done in less than an hour and, in some unfortunate places, a small chance of 60 mm in a short time.

"Given the persistently hot weather, large parts of the UK remain at risk of thunderstorms and possibly the effects of heavy rain until early next week."
Spokesman Oli Claydon added, "The fairly high temperatures overnight means a fairly tight, muggy feeling, consistent with thunderstorms forecast through Monday.
Some areas could see up to 40-50 mm (1½-2in) of rain in two to three hours (today), with 50-70 mm (2-2½in) possible in three hours on Sunday.
"At the moment there are ongoing thunderstorm warnings until Monday."
The prospects for Saturday should be good in the west, but with thick clouds from the North Sea in the northeast, the Met Office said.
Mr. Claydon added, “In this type of weather it is important to keep an eye on the forecast as it can change very quickly.
“Due to the nature of thunderstorms, it is quite difficult to pinpoint exactly where. We can expect them anywhere in these yellow warning areas. & # 39;
Neil Davies, Flood Duty Manager at the Environmental Protection Agency, said, “Isolated thunderstorms can cause sudden surface water and river flooding, which in some areas can result in flooded properties and severe travel disruptions. Further surface water and river floods are possible until Sunday. & # 39;
The weather will be an extra kick in the teeth for the thousands of Britons who made a maddening rush across the canal last night to get home before the government's 14-day quarantine at 4 a.m.

From 4 a.m., anyone arriving from France must be quarantined for 14 days after the country reported a surge in coronavirus cases.
The hour 11 move caused havoc for an estimated 500,000 British vacationers in France – including a couple who spent £ 1,000 on Eurostar business class seats and a family who drove home for 12 hours.
A mother had to leave two of her children with her husband when she fled France on the last Eurostar train.
The woman, who had to return to the UK due to her job before the quarantine began, could only get tickets for herself and her baby.
She now fears that her two daughters – who will return on Monday – will not be out of quarantine when their school returns.
The woman, who did not reveal her name, told Sky News: "This completely ruined our summer. I do not know what to do now. I am so upset about it. & # 39;
There are also fears that the new rules will result in thousands of children missing the start of the school year as students who do not return to the UK by Tuesday night will still be self-isolating at home when the majority of schools return in September 2 .
With limited capacity for flights, ferries and the Eurotunnel, many have no choice but to stay in France – or pay high prices on some of the remaining tickets.
Some tourists were given less time to avoid quarantine after the Scottish and Welsh governments called for the rules to be put in place the day before.
In the meantime, France is likely to impose quarantine restrictions on people arriving from the UK starting Monday, which means UK travelers will also need to self-isolate when they arrive there.
