Forecasters today predicted that the unrelenting rain which has been battered Britain shows no signs of easing off - with another four inches of wet weather expected in the South East tonight and tomorrow.

Forty two areas have been put on flood alert today after nearly a month and a half's worth of rain fell on parts of the South East in 36 hours.

The South West and mid Wales have been worst hit by the rain which has battered Britain and in Wimbledon, London, it has been raining continuously since 4pm on Sunday.

Elsewhere Brighton has had nearly three times the average rainfall for the whole month in 11 days, and the Environment Agency still has flood warnings for the region.

Up to 30mm of rain is expected to fall in the next three hours while tomorrow up to 60mm could fall in parts of Cornwall.

In Felpham, Bognor Regis, the A259 Felpham Way resembled a river between the houses today after flood water rose almost waist-deep in places. Cars lay submerged and abandoned, while residents were spotted making use of boats if they had them.

The Environment Agency has issued more than 40 flood alerts across England and Wales, and five more severe flood warnings in the region. The South East is set to bear the brunt of the weather with 33 flood alerts followed by the Anglian region with five alerts in place.

The wet weather is set to continue for the coming days, and could take a turn for the worse on Friday.

Julian Mayes a forecaster for Meteogroup, said: 'The reason it has been so wet in the South is because the jet stream has switched from its normal position just to the north of Scotland to down over southern England this month, and depressions follow that feature.'

On the other hand, Scotland is enjoying unusually dry weather for this time of year.

Glasgow has had 28mm (1.1in), and Oban, normally one of the wettest parts of the western Highlands, has had 9mm (0.4in) this month.

'It's a reversal of the average weather pattern,' Mr Mayes said. 'Normally it gets wetter as you go to the North West. This month it gets wetter as you go south.'

The South East has the most flood warnings in place today and was one of the worst affected areas yesterday. Flood waters coursed through homes, down roads and even closed a hospital yesterday. More than three inches, or 80mm, fell in parts of the country after the rains began on Sunday night.

DON'T WORRY, JULY'S GOING TO BE A SCORCHER

Those reaching for the how to immigrate handbook should be aware that scorching weather is predicted for the first two weeks of July AND for a two-week spell in August.

Long-range weather forecaster David King said London was set to 'swelter' during the second week of the Olympics, with temperatures hitting more than 30C.

Wimbledon will also bask in sunshine during the second week of the tournament - but only after rain has washed out the first week of tennis. Mr King, whose meteorological skills were used by the royal family when planning Prince William and Kate Middleton’s wedding, said: 'Unfortunately this wet weather and cold easterly wind is going to stay with us now until the end of June.

'But the heat will arrive in the first week of July and last right through to the 15th. Temperatures might even get to 30 by the middle of the month.'

And despite the recent deluge of rain, Mr King said the hot, dry weather predicted for July and August would mean the drought in the South East was likely to continue into next year.

The 72-year-old amateur forecaster, who uses phases of the moon and his observations of nature to predict the weather, said by the end of the summer the drought would be worse than that of 1976 - when some households were even left without tap water.

Mr King, whose forecasts focus on London and the South East, also said there won’t be a repeat of last year’s glorious autumn.

He said: 'The first two weeks of September will be pretty good, but then rain storms will come in.'

In Wiggonholt, West Sussex nearly a month-and-a-half's worth of rain has fallen in just 36 hours. 72mm fell in the 36-hour period since Sunday evening. The average rainfall for the area is 52.9mm

The avevage rainfall for the whole of June in the South-East is just two inches, or 50mm.

The Environment Agency warned of further rain across the South East today and unsettled weather for the rest of the week. Although there was a lower than forecast amount of rain overnight, more heavy rain is expected into the weekend, it added.

Heavy rain is expected to continue today across the southeast and parts of East Anglia likely resulting in flooding, especially in Sussex and Hampshire. Around 15 to 25mm of rain has been forecast in the worst affected areas in the South today.

Met Office forecaster, Dan Williams, said: '15 to 25mm isn't particularly significant but when it comes on top of the rain we've already had it is significant and increases the potential for flooding.'

He added the continuous rain was 'reasonably unusual but not unprecedented' for this time of year.

Julia Simpson, the Environment Agency's regional duty manager, added: 'Some rivers have stabilised but others are yet to peak as the water moves through, so we could potentially see further flood alerts and flood warnings being issued.'

The torrential rain caused a seven-mile long traffic jam on the busy M3 motorway this morning leaving commuters three hours late for work.

Two lanes were closed on the Southbound carriageway between Fleet and Hook, Hants, as flood drains blocked.

Motorist Dan Newson, 24, said: 'I was travelling to work at around 5am, it usually takes no time at all to get there but I was almost three hours later for work.'

A Tesco supermarket’s bakery in Cosham, Hants, was evacuated after isles flooded due to a drain inside the store spouting out water.

As river levels continued to rise to dangerous levels today, nearly 500 homes in Oxford were hit by power blackouts.

It meant a cold breakfast and no hot water for families in the north of the city around the Summertown area. Southern Electric spokesman Hannah Gleave said about 470 homes in the area had been affected, with power going off at 6am.

And yesterday a seven-strong team of RSPCA officers staged a dramatic two-hour rescue after a herd of cattle became trapped in a flooded field in Broadbridge Heath, West Sussex after the River Arun burst its banks.

Inspector Rosie Russon, who led the specialist water rescue team, said: 'The farmer was really worried that they were going to drown because the water had reached 5ft and was still rising.

'The cattle were stuck on a small patch of the field and we had to persuade them to walk through 5ft of fast flowing water to get to the gate and out on the lane so they could be moved to another field.

In Hook, Hampshire, a woman had to be rescued from her car by firefighters after her vehicle became stuck in floodwater as she followed directions on her satnav.

The driver, from Mansfield, Nottinghamshire, accidentally drove into a ditch at 11.55am today - she could not see the edge of the road because of the water levels, according to Hampshire Fire and Rescue Service.

The dreadful conditions are set to continue into tomorrow as well. Showers, some heavy are expected to hit northern and western parts of the UK and there’s also a risk of thunder for Wales and in the south west.

The sun may show itself briefly on Thursday but it will be replaced by persistent rain for those in the south west and south Wales through the day.

And on Friday an area of heavy rain is expected to move northwards across the UK. The south can look forward to frequent heavy downpours with a risk of thunder.

Yesterday, Butlins holiday camp told holidaymakers not to come after many of the roads in and out of Bognor Regis were closed by police due to the adverse weather and heavy flooding.

It managed to reopen to guests today after the worst of the water receded.

Meanwhile, scientists are to investigate whether severe flooding has polluted land with toxic metals.Parts of Ceredigion in mid Wales were flooded by 5ft of water, with record high river levels in parts on Saturday.

A major clean-up operation continues in Aberystwyth and the nearby villages of Talybont, Dol-y-Bont and Llandre and other areas affected by the flooding. There are fears that some areas could have been contaminated with harmful metals from abandoned mines.

A team from Aberystwyth University is to survey the catchment areas of the rivers Leri, Rheidol and Ystwyth.

Mark Macklin, a professor of physical geography at Aberystwyth University, said the force of the flood waters could have eroded river banks which stored harmful metals, including lead and zinc.

He told BBC Wales: 'Much of Ceredigion was affected by metal mining, but most of it finished before the start of World War One. As a result of the mining, rivers and river banks in the area have been contaminated from the mines themselves right the way down to the sea.

'There are concerns that farmland has been contaminated and this could pose a risk to animals and crops. We’ll take fresh flood deposits, such as silt, and they will be chemically analysed. We will, hopefully, have some answers in a month or so.'

West Sussex was hit hard yesterday, with at least 26 apartments flooded in Littlehampton and firefighters receiving 200 flood-related calls.

The basement of Worthing Hospital was also under water, forcing emergency patients to be diverted to neighbouring Brighton and Chichester for several hours.

But the disruption from the deluge was not contained to the south coast. In Leeds, heavy rain caused drains to back up and roads and homes to flood, with water up to four feet deep.

Overflowing drains also caused 20 beaches on the Kent coast to be closed when raw sewage ran into the sea.

The occupants of two cars had to be rescued from floodwater just half a mile from each other in Southwick, Hampshire, in separate incidents.

A man was rescued from his 40ft barge after rising river levels pinned it against a pontoon in Worcestershire.

And in Bracknell, Berkshire, Fox Hill Primary School was closed on the first day back after half-term as its drains could not cope with the rainfall.

Sports fans also suffered disappointment with all the first-day matches at the Queen’s Club tennis tournament in London postponed and cricket abandoned at the Test match between England and the West Indies at Edgbaston.

Rita Haskett, 69, who came from Taunton, Somerset, to watch the tennis, said: ‘This is the third time we have come to Queen’s and this is the worst weather we have had. It just hasn’t stopped raining.’

Elsewhere, the RSPCA said it was working closely with fire services to rescue stranded animals, including 20 cows at Cuckfield Road near Hurstpierpoint, West Sussex, left marooned on a river bank.

Gemma Plumb, of forecasters Meteogroup, said there would be more rain and overcast skies for the rest of the week.

Incredibly, despite the torrential conditions, the Met Office said the UK was still below its average rainfall for the year. Between January and May, 392.5 millimetres of rain fell across the country, compared with an average of 439 millimetres.

In southern England – including drought-hit areas in East Anglia, the South East and the Thames Valley – 281.8 millimetres of rain fell from January to May. The average is 303.2 millimetres.

Meanwhile, a special disaster fund is to be set up after more than 1,500 people were moved from their homes and 150 rescued in Mid Wales over the weekend.

I have spent time on the met office web site and there is absolutely no evidence of 4 inches of rain in the next 24 hours in the south east, in fact the next two days offer a brief respite before the next lot on Friday. Another misleading and scaremongering headline from the DM forecasting service.

doesnt understand this northern and southern divide - I live in Crawley but i love the north did my degree in manchester and have family in Lancashire - some of you people saying you dont want there water need to seriously grow up , theres nought wrong with it and if you needed would accept it straight away , if anything northern water is cleaner than southern but its all the UNITED KINGDOM'S

This weather has left me very depressed! WHERE IS OUR SUMMER ?????? - Stephen J Cole, Hitchin , Hertfordshire, 12/6/2012 11:13 Welcome to the UK , home of bad weather

Is there still a hosepipe ban?

Ahhh, there's just nowhere like England on earth - and no people like the English. Just 3 weeks ago with that week of hot sunny weather people were moaning about how it was "too hot" and they couldn't sleep. Now the same people are complaining that the weather is depressing. I love it! WIthout the variable weather in UK, conversations between strangers would literally dry up. And let's face it - England is so beautiful and green - and that's because of the rainfall.

Good, can we all go out and water out gardens now then?
