Red alert! Met Office issues highest-level warning for life-threatening Storm Dennis

The ‘life-threatening’ Storm Dennis has caused flooding carnage all over the country this morning, after the Met Office issued its highest level warning with heavy rain and fierce winds of up to 91mph lashing Britain.

At about 11am on Sunday there were 250 flood warnings, meaning immediate action is required, and 344 flood alerts warning people to be prepared, covering an area from Scotland’s River Tweed to the rivers of west Cornwall. 

The situation was said to be particularly ‘life-threatening’ in South Wales, where the Met Office issued the red warning due to heavy rainfall and flooding risk. It is the first red warning issued for rain since 2015. 

‘It’s quite an extreme move but we have seen widespread rainfalls across the whole region,’ forecaster Greg Dewhurst said. 

A high street in Pontypridd, South Wales was flooded as the River Taff burst its banks, with ambulances among several vehicles submerged in water. Several high street stores, including Costa Coffee and Boots, have been blocked by the rising floodwaters.  

Meanwhile, a search is also underway for a woman feared to have been swept to her death on Brighton seafront in huge Storm Dennis waves today.

She was seen in the water around 2.45am and despite hours of searching, there was no sign of her with rescuers fearing the worst. An 11-year-old boy was found safe and well in Dundee, Scotland, after going missing last night.

Nearly 30,000 homes in towns and villages across Dorset were left without electricity and heating after torrential rain and howling gales from Storm Dennis knocked out power supplies, while residents were forced to evacuate their homes in parts of the Scottish Borders and in Wales.

Severe flood warning were issued for the Scottish Borders and for the River Neath in South Wales, while the River Taff burst its banks and left cars floating in roads with water rising up to invade neighbouring homes.

Homeowners say they received flood alerts at 4am telling them to take immediate action and move to safety.

One mother-of-two said: ‘I was woken up by a phone call and then had a voicemail saying to get to safety. It was really frightening as I’ve never experienced flooding like this before.’

An ambulance was spotted stranded in the water at nearby Nantgarw following a night of heavy downpours, while a high street was also submerged.

Natural Resources Wales warned the ‘very high’ river could have ‘significant impact downstream towards Cardiff.’ 

Gwent Police told residents in Skenfrith, Monmouthshire, to leave their homes due to flooding. Emergency centres are also being set up in a string of towns to provide cover for those affected.

Merthyr Tydfil County Borough Council also set up centres at Merthyr and Aberfan Leisure Centre. Villagers in Tonna near Neath, were evacuated by bus on Sunday morning.

In the 24 hours to 7am, Tredegar in south-eastern Wales received four inches of rain, while the fastest gust recorded in the same period was in Aberdaron where 91 mph was measured at 6pm on Saturday.

Weather station monitoring Storm Dennis winds has £4,000 of equipment blown away by the gales 

Staff manning a weather station on the Isle of Wight were counting the cost of the storm today.

Their valuable equipment to measure wind speed was blown away and they are still trying to find it.

The equipment, worth about £4,000, was checking the terrifying wind speeds when it was torn from its mountings.

Isle of Wight Weather Centre meteorologist David Carrington posted online: ‘The weather centre was also a causality of the storms. One of our Stevenson Screens worth over £1,000, plus £1,500 worth of equipment inside the screen, plus one of our pro weather stations attached to the outside of the screen worth another £1,500 was totally blown away by the strong winds.

“The equipment, set up as a remote station in a secure and secret location on Wroxall Downs, stopped transmitting data to us.

“We went up to have a look and it was just gone. We are gutted to say theleast.”

He’s hoping it will be handed back by anyone finding it and it hasn’t been smashed beyond repair.

Rail services were suspended across South Wales after tracks were submerged by rain, while the line between Derby and Long Eaton was also closed.

Flooding saw the M54 westbound closed at Telford, along with the A616 around Stocksbridge in South Yorkshire and the A52 between Stragglethorpe and Gamston in the East Midlands, Highways England said.

It comes as two people were killed by Storm Dennis yesterday, an 18-year-old man who got into difficulty in the sea off Kent and another who fell overboard from a fuel tanker near Margate Harbour. 

Relief from Storm Dennis is still some distance away, the Met Office’s Mr Dewhurst said, adding that ‘heavy rain and strong winds’ would continue across large parts of the UK today.

‘South Wales will see a lot of rain fall before Dennis moves north later to Scotland and Northern Ireland.’ 

Earlier, the Ministry of Defence deployed British Army personnel to assist people in West Yorkshire areas badly hit by flooding during last weekend’s Storm Ciara.

Flights have been grounded for safety reasons, with British Airways and easyJet confirming cancellations.

More than 230 easyJet flights in and out of the UK on Saturday were cancelled, while several sporting fixtures were also called off due to the weather.

Two bodies were pulled from rough seas on Saturday, before the worst of the storm hit.

One man was found following a huge search operation off Margate after an early-morning distress call, while another was found at Herne Bay.

Costa and Boots submerged by Storm Dennis floodwaters as River Taff bursts its banks 

The River Taff in Pontypridd, South Wales burst its banks this morning, leaving ambulances stranded and cars floating in floodwater. 

Footage posted on social media shows Pontypridd High Street submerged in floodwater with Boots and Costa unreachable, as Storm Dennis ravages the nation.

The fast-moving floods have also invaded homes in the town, which is near Cardiff.  

Homeowners say they received flood alerts at 4am telling them to take immediate action and move to safety.

One mother-of-two said: ‘I was woken up by a phone call and then had a voicemail saying to get to safety. It was really frightening as I’ve never experienced flooding like this before.’

Virgin cancelled four long-distance flights from Heathrow to Hong Kong and Boston scheduled for yesterday and today.

Passengers were booked on to other services. Meanwhile, British Airways confirmed 40 short-haul flights to and from Heathrow last night and this evening had been cancelled, with routes to Amsterdam and Glasgow the worst affected.

Under European air passengers’ rights rules, airlines that cancel flights have a duty of care to provide replacement transport, as well as hotels and meals if necessary.

BBC journalist Christian Fraser and his wife Topaz were among the holidaymakers whose travel plans were ruined.

They were due to fly to Gran Canaria yesterday on a £3,500 easyJet package break, but were told the flights were cancelled and given no other information.

‘No one’s helped us and no one seems to know what’s going on,’ Mr Fraser told The Mail on Sunday.

‘We now don’t know whether to try to get to Gran Canaria through our own means. We tried to contact easyJet for help on Friday night but the call centres shut at 8pm.’

Both the A14 Orwell Bridge in Suffolk and the M48 Severn Crossing eastbound between Monmouthshire and South Gloucestershire were shut due to strong winds while drivers were warned that other bridges and roads may be closed.

Desperate search for woman swept out to sea by huge waves in Brighton caused by Storm Dennis

A search is underway for a woman feared to have been swept to her death on Brighton seafront in huge Storm Dennis waves today.

She was seen in the water around 2.45am and despite hours of searching, there’s was no sign of her with rescuers fearing the worst.

The Coastguard helicopter spent more than two hours with floodlights scanning the surface of the sea between the Marina and Palace Pier. The search is resuming now it’s daybreak.

A spokesman for Sussex Police said ‘The alarm was raised by members of the public at about 2.45am after a woman was seen in the water.

‘She has not yet been located and the Coastguard are preparing to recommence their search shortly.’

A body was found after a seven-hour search in what the coastguard described as ‘very rough’ seas.

In Yorkshire’s Calder Valley, which was still recovering from the damage caused last week by Storm Ciara, 75 members of the 4th Battalion, Royal Regiment of Scotland, and another 70 reservists were deployed to help erect barriers and repair flood defences.

John Curtin, the Environment Agency’s executive director of flood and coastal risk management, said he was most concerned about Cumbria, Lancashire and Yorkshire.

‘This storm could be a step up from what we have seen before,’ he added. 

‘We had a big storm last weekend, [now we have] saturated catchments, snowmelt and rainfall, so it is the perfect storm.’

The Environment Agency, which issued 34 flood warnings and 246 alerts, said preparations were under way to operate defences, flood storage reservoirs and temporary barriers to protect communities.

Environment Secretary George Eustice said: ‘We are fully focused on ensuring that communities are protected and have access to the support and advice they need to stay safe this weekend.’

The Met Office last night confirmed that Storm Dennis was a ‘bomb cyclone’, which means its air pressure has dropped by 24 millibars or more in 24 hours.

Met Office chief meteorologist Steve Willington said: ‘Storm Dennis will bring another very unsettled spell of weather this weekend with a risk of flooding, particularly in parts of England and Wales and also southern Scotland, where snowmelt will add to the flood risk.

‘Following Storm Ciara last weekend and further spells of rain this week, the ground is already saturated in places. Our advice is to keep an eye on the latest forecasts and weather warnings and to follow the safety advice.’

What is a ‘Bomb Cyclone’?

A bomb cyclone is formed when the air pressure of a storm plummets by at least 24 millibars in 24 hours, causing huge storms and wind speeds of up to 100mph.

A millibar is simply a unit of measurement used by meteorologists to describe air pressure – the force exerted by the air’s weight.

The standard surface pressure on Earth is 1013.2 millibars, and the lower the pressure drops within a cyclone, the more severe a storm it creates.

On Thursday, Storm Dennis was classified as a bomb cyclone after the pressure dropped by 46 millibars in 24 hours.

The name developed in the 1940s and 1950s when experts at Bergen University in Norway began calling storms created over the sea ‘bombs’ because they formed far more quickly than those over land.

By the 1970s, the terms ‘explosive cyclogenesis’ and ‘meteorological bombs’ were being used by Professor Fred Sanders from the Massachusetts Institute of Technology in scientific journals. The term ‘bomb’ has proved controversial. 

When European researchers argued the term was too warlike, Prof Sanders asked: ‘So why are you using the term front?’

Soldiers drafted in as village faces being swamped for the SECOND time in a week

By Jacinta Taylor for the Mail on Sunday 

They were warned to brace themselves for another storm but it was still a sight that threatened to break hearts and undermine Yorkshire grit.

Residents in the close-knit village of Mytholmroyd woke yesterday to find soldiers on their streets, the clearest sign that the Calder Valley was due for another devastating flood.

Since 2012, the village has flooded three times – the last only a week ago when torrential rain from Storm Ciara caused the River Calder to swell to a record 16ft.

Some 500 homes and 400 businesses were flooded.

Many people whose homes back on to the river have either temporarily moved out or carried everything they own upstairs and out of harm’s way. Those who have chosen to stay have stocked up on food and bottled water. Soldiers are pictured placing sandbags along a river in Doncaster this week

Soldiers on the streets meant that once more, those homes and treasured possessions, potentially even lives, were under threat. Around 100 troops were helping to build temporary metal flood defences ready for Storm Dennis.

Last week’s muddy brown floodwater had overwhelmed the town, prompting anger that a £30 million flood defence scheme was taking too long to complete.

Resident Cynthia Stringer, 68, said: ‘They built the new wall about a foot lower than the old one – that’s never going to work, is it? The water just poured over the top.’

Many people whose homes back on to the river have either temporarily moved out or carried everything they own upstairs and out of harm’s way.

Those who have chosen to stay have stocked up on food and bottled water.

They certainly know the drill. First, there is a warning text message from the Environment Agency, followed by the flood sirens sounding in Mytholmroyd and other communities along the Calder Valley.

Resident Nick Ames, 51, said from his stone cottage: ‘There’s no point in crying about any of this – all you do is just add to the flood level. I think most people here have a ‘keep calm and carry on’ approach.’
