Britain will be drenched by up to TWO INCHES of rain today with the threat of thunderstorms later

Britain will be battered by two inches of rain today as weather warnings covering vast swathes of the country spark severe flooding fears.

Marking the bitter end to a sweltering summer, parts of the UK could be drenched by a month’s worth of rain – some 2.6 inches – in just 24 hours today as Storm Alex wreaks havoc for a third day.

And the wet weather is unlikely to ease off as the day goes on as thunderstorms could hit the south east this evening. 

It’s not all doom and gloom, however, as while Machrihanish in Scotland will see today’s lowest temperature of 0.9C, parts of Sussex are set to bathe in a balmy 16.6C.

South Wales, Bristol and Gloucestershire all fall into the Met Office’s amber weather warning, meaning the downpour could cause fast flowing or deep floodwater putting lives at risk.

The warning level – last issued before the pandemic – also means Britain could see mass transport chaos with dangerous driving conditions, road closures and delays and cancellations to public transport all expected.   

These warnings have now been extended until midday, having previously been due to expire at 6am this morning.

Yellow weather warnings are still in place from Exeter in the south stretching up to the northern-most point of Scotland. 

The British public have now been warned to expect further flooding and transport disruption, with more than 50 flood alerts and a small number of flood warnings issued as the UK’s wet weekend rumbles on.

Met Office meteorologist Greg Dewhurst said areas within the amber warning areas could see 0.8 inches of rain, with as much as two inches over higher ground on Sunday. ‘Still a fair bit of rain to come over the next 24 hours,’ he added. 

The Met Office said in the 42 hours running up to 6pm on Saturday, there had been 4.6 inches of rain at Blackpitts Gate in Somerset, and four inches at Princes Marsh in Hampshire.  

Flooding has hit train services in London and Scotland, with services between St Pancras and Finsbury Park being cut as journey times are taking longer due to flooding on the track.   

A family of four had to be rescued by firefighters from a road in Billericay, Essex, yesterday after their car became trapped in floodwater, while police issued warnings to drivers after a number of crashes on waterlogged roads.

ScotRail said following yesterday’s bad weather, affected areas will need to be checked first thing this morning to make sure routes are safe for services to run, resulting in some lines being closed.

RAC Breakdown spokesman Rod Dennis said that road conditions would be ‘miserable if not downright dangerous’ for drivers this weekend. He added that drivers need to be prepared for ‘an ugly mix’ of surface spray, gusty winds and more than likely some disruption on the roads.  

A woman was rescued by her husband after driving into four-foot-deep water in Essex this morning while train lines have becomes submerged as Britain is battered by heavy downpours and 90mph gales from Storm Alex.

North West Motorway Police tweeted: ‘If you are using the network this afternoon – please slow down. Thankfully this was a damage only RTC. 

‘Lots of stand water across the network today. Please allow extra time for your journey.’

Mark Newberry, commercial director at the breakdown cover provider, advised drivers to remain cautious and to ensure that they carried out the appropriate safety checks before travelling anywhere.

While RAC Breakdown spokesman Rod Dennis said that road conditions will be ‘miserable if not downright dangerous’ for drivers this weekend.  

He said they will need to be prepared for ‘an ugly mix’ of surface spray, gusty winds and more than likely some disruption on the roads. 

Bookmaker Coral has also made it odds-on, at 4-5, that this October goes on to be the wettest since records began, as the month begins with torrential downpours across the nation.

Coral’s Harry Aitkenhead said: ‘It’s only just begun but we already make this October odds on to enter the record books as the wettest that we have ever had. It’s going to an absolutely soaking few months.’ 

Additionally, the Met Office has warned that some areas of the country could be hit with flooding, with weather warnings having been issued for large areas of the country.

Met Office forecaster Greg Dewhurst said: ‘It is going to be raining and horrible all day. If you have to travel take extra time on your journey, the roads will be pretty treacherous at times with poor visibility due to the heavy rain.’ 

This follows the damage already inflicted on parts of the UK by Storm Alex on Thursday as trees were trampled.

Police have also warned thrill seekers to keep themselves out of harm’s way as foam is spotted ‘being blown about half a mile inland’ at Perranporth beach in Cornwall.

An officer said: ‘If you’re gonna go out taking photos, videos, put yourself in a safe position to do so. Don’t put yourself in any harm’s way alright because that will mean you’re likely to result in a call out for emergency services.

‘It says something when the foam is being blown about half a mile inland. So it’s pretty rough.’ 

More than a month’s worth of rain could be recorded in some places after Storm Alex ripped off a school roof and felled trees in Brittany, France.

Thousands of visitors travel out to the island in the middle of Poole harbour in Dorset to see the ‘Squirrel Nutkins’ scampering among the pine trees.

With Storm Alex still raging, a National Trust spokesperson said: ‘We’ve made the decision to close the island today.

‘There’s another weather front blowing in and we need to put the safety and comfort of our visitors first. We hope to re-open as normal on Sunday. All those with pre booked tickets will be contacted as soon as possible.’ 

The opening semi-final of the Vitality Blast Finals Day at Edgbaston has also been delayed due to rain.

The match between Surrey and Gloucestershire was scheduled to begin at 11am but the inclement weather meant proceedings were delayed. An inspection was due at 11am.

The second semi-final, between Nottinghamshire and Lancashire, was due to start at 2.30pm.

Meanwhile, a motorist came within a second of being killed when a huge tree blew over in front of her car.

Joanne Page, 58, was driving home from the hairdressers when the 70ft oak tree came down during Storm Alex. Her car ground to a halt just inches away from trunk of the fallen tree.

The dramatic incident happened A337 near Lymington, Hants, at 10.30am yesterday. She said: ‘A man was driving behind me when it happened. We both got out the car and he asked if I was ok, I said I was fine and he said if I was a second faster I would not be here.

‘It’s extraordinary nobody was hurt.’

Ms Page said she saw the tree falling in front of her just as she approached it on the 40mph road.

She said: ‘I could see the wood splitting and it fell so elegantly. It was quite a majestic fall, I feel privileged to have seen it more than anything. But if my car had been under it, I would have struggled to get out in time. I’m now going to buy a lottery ticket.’

The tree was later cleared from the carriageway by highways officials. 

Amazingly, firefighters in Sussex trudged through the pouring rain and mud to put out a blaze in a bush last night.

Somehow, despite being saturated, the undergrowth caught fire at Duke’s Mound, a hilltop beauty spot on Brighton seafront.

As Storm Alex wreaked havoc across the UK, the fire crews found themselves spraying water on the flames which lit up the sky.

Crews from East Sussex Fire and Rescue were called to Duke’s Mound at around 7pm last night and did not pack away their hoses until 9.10pm. They said the fire was ‘deep-seated’ in the rain-soaked bushes, close to Brighton Marina.

Meanwhile, Met Office deputy chief meteorologist Laura Ellam said that the rainfall could prove ‘challenging and disruptive’.

Downpours are forecast every hour for parts of South East England until Monday lunchtime putting hundreds of thousands of families on flood alert, while commuters face a hellish return from work yesterday.

A peak wind gust of 115mph was recorded in Brittany on Thursday night as Alex came ashore over north-western France, which matches the peak UK gust for the Great Storm of 1987 – although the French record is 138mph. 

The top speed in the UK on Friday reached 71mph. The storm was named Alex by French forecasters because it originated on the Continent, but it would have been called Aiden if it was named by UK and Irish forecasters.

Widespread power cuts have hit southern England, with Scottish and Southern Electricity Networks recording unplanned outages in more than 20 areas including Portsmouth, Southampton and towns east of Reading. 

Western Power Distribution has also recorded incidents in Devon, Cornwall, Dorset and Somerset. In addition, outages affected nearly 1,230 homes in Newark-on-Trent, Nottinghamshire and 550 in Crawley, West Sussex. 

Power board engineers were working in increasingly atrocious conditions to restore supplies but with winds increasing in strength, trees were at risk of being blown on to overhead cables. 

Runners tackling 26.2 miles of the London Marathon on Sunday are likely to face rain and strong winds. While elite runners will race on a looped course, 45,000 other participants will choose their own route tracked by an app. 

But the Met Office does not expect it to be the wettest marathon ever. That record was in 1983 when 0.9in of rain fell in Greenwich, while the windiest was in 1986 when 35mph was recorded at Kew Gardens.  

Thursday’s weather warning covers southern counties of England from Cornwall to Kent as well as South Wales and Herefordshire until 8pm. By 8am on Friday, Alex was centred close to the Channel Island of Alderney.

Up to two inches of rain could fall, while gale force winds are set to reach 65mph on exposed coasts and 55mph inland. The Met Office is warning of flooding and ‘dangerous’ driving conditions due to spray and high winds. 

In the wake of the storm, a second system is due to bring more heavy rain over the weekend. This has triggered a second set of weather warnings which cover almost all of England, all of Wales and the eastern side of Scotland.

The warnings last from 3am tomorrow until 6pm on Sunday – and include a ‘danger to life’ alert due to the chance of ‘fast-flowing or deep floodwater’. 

‘There is a small chance some communities could be cut off,’ the Met Office states. It also said there is also a risk of landslides and ‘very difficult driving conditions’.

Met Office spokesman Bonnie Diamond said: ‘Unusually, the weather system moving in on Saturday is coming from the East, rather than the South West.

‘It means eastern counties which are usually more sheltered will bear the brunt of the system. Over the weekend, some places could see more than the average rainfall for the whole of October.’

The wettest conditions are set to be in eastern Scotland but very heavy rain is also expected on the high ground of Wales and South West England.

Between 4-5in of rain is expected in the worst-hit places, with one to two inches elsewhere. The normal average rainfall for the whole of October is 5in in the UK and 3.8in in England.

The most significant rain is due tomorrow before turning more showery on Sunday but some places could still see heavy downpours.

Chief meteorologist at the Met Office, Steve Ramsdale described the forecast as a ‘miserable end to the working week’ and warned of gales before another band of wet weather arrives for larger swathes of the country.

He added: ‘As the strong winds and rain associated with Storm Alex clear away from Britain later on Friday, another low-pressure system moves towards the UK from the east bringing further very heavy rain and strong winds to many over the weekend.’

The Met Office’s concerns were echoed by the Environment Agency, which said: ‘Heavy rain will bring the potential for surface water flooding and perhaps some river flooding across the south of England on Friday.

‘More widespread and persistent heavy rain across much of England will bring the potential for further river and surface water flooding over the weekend.

‘We urge people to stay away from swollen rivers and not to drive though flood water, it is often deeper than it looks and just 30cm of flowing water is enough to float your car.’

Miss Diamond added: ‘On Monday it is due to become a little less unsettled and windy. There is still due to be a chance of showers but it certainly won’t be as wet. The weather is due to stay unsettled into next week.’ 

And RAC breakdown spokesman Rod Dennis said: ‘Heavy rain will make road conditions miserable if not downright dangerous for drivers this weekend, and they’ll need to be prepared for an ugly mix of surface spray, gusty winds and more than likely some disruption on the roads.

‘Floods are also a possibility so drivers should remember never to attempt to drive through water unless they know for sure that it’s shallow enough. For drivers who are unlucky enough to breakdown in the horrid conditions, our patrols will be working around the clock to get them moving again.’

Looking further ahead, the Met Office said unsettled weather is forecast to continue until the middle of the month.

Its forecast states: ‘An unsettled picture is likely for this period, with all parts of the country seeing showery spells as well as times of more prolonged rainfall.

‘Southern and western areas are expected to see the worst of these conditions with the most frequent and heaviest rainfall. Drier and calmer conditions could be seen at times, but likely only for short interludes.

‘Largely windy for most of the country during this period, with a risk of gales at times, particularly along western and south-western coasts. Overall, it is likely to feel rather cold.’

A drier spell, with the chance of sunny days but fog and frost by night, is not expected until the second half of the coming month.

How the Great Storm of 1987 claimed 18 lives, flattened 15million trees, caused damage costing £1.5billion and saw Michael Fish lampooned forevermore

The Great Storm of 1987 battered England and Wales, leaving 18 people dead and causing £1.5billion worth of damage to the economy.

In the early hours of October 16 winds peaked at 115mph, damaging buildings and felling 15million trees in the south east of England.

Millions of homes were left without power for at least a few hours, with some having no electricity for days as trees fell on power lines, disrupting supplies.

Whilst most of England and Wales experienced wet and windy weather that night, it was southern and eastern parts of England that were worst hit. A ship capsized at Dover, and a Channel ferry was driven ashore near Folkestone.

Veteran weatherman Michael Fish bore the brunt for famously telling the nation there was no hurricane in the offing, just hours before it arrived.

At the time Mr Fish told viewers tuning into the broadcast: ‘Earlier on today, apparently, a woman rang the BBC and said she heard there was a hurricane on the way; well, if you’re watching, don’t worry, there isn’t, but having said that, actually, the weather will become very windy, but most of the strong winds, incidentally, will be down over Spain and across into France.’

But in 2011, one of his former colleagues finally stepped forward to take the blame for the Met Office’s botched forecast.

Bill Giles, who was chief forecaster at the time, admitted that he was in fact responsible for the lunchtime broadcast on October 15 in 1987.

A Sealink ferry was forced onto dry land by the extreme winds that hit England and Wales in October 1987

A Sealink ferry was forced onto dry land by the extreme winds that hit England and Wales in October 1987

It was the worst storm since 1703 and a public enquiry was announced shortly after the storm and an internal enquiry was conducted by the Met Office.

The official forecaster wrote: ‘We now know that the strength of the storm was boosted by a phenomenon known as the ‘Sting Jet’, where cold dry air descends into storms high in the atmosphere.

‘Rain or snow falling into this jet of air evaporates and cools the air further, adding more energy which translates into stronger winds. By the time this ‘sting in the tail’ reaches the ground it can produce winds of 100mph which are concentrated over a small area.

‘In 1987, no-one knew sting jets even existed, but now they are well understood and included in forecast models. The storm which affected Scotland in December 2011 was boosted by a sting jet, explaining the maximum gust speed of 164mph recorded on top of Cairngorm.’
