An 'unprecedented' El Niño will trigger severe storms and power cuts that could leave millions offline this winter, experts have warned.
uncertain
experts → trigger → millions
Around 26.7 million Britons lost broadband connection last year, according to new research from Uswitch - up almost a fifth on the previous year.
uncertain
Britons → lose → year
Power cuts are now the leading cause of internet outages, eclipsing provider faults and contributing to 41 per cent of service failures.
asserted
cuts → lead → failures
Now, with a Super El Niño forecast to bring wet and stormy conditions this autumn and winter, Uswitch is warning households to prepare for even more service blackouts.
asserted
Uswitch → bring → blackouts
Max Beckett, Uswitch broadband expert, says: 'Your broadband is only as reliable as the electricity behind it, and power cuts are now the main reason people lose their connection.
asserted
people → say → connection
'Keep a charged mobile to hand, and if anyone in your home relies on the landline, ask your provider about a battery backup.'

Experts warn that this year's 'Super El Niño' could trigger storms and power cuts that will leave millions offline
Earth's climate engine is running hot, with unusually warm conditions forecast across much of the globe during the coming months as the powerful El Niño gathers strength.
uncertain
Niño → warn → strength

Stormy weather can cause power outages and disruptions as heavy winds, falling trees and lightning strikes damage power infrastructure or trigger automatic safety shutdowns.
asserted
winds → picture → shutdowns
When these power cuts hit, they also take down broadband and landline services with them.
asserted
they → hit → them
As the growing Super El Niño begins to affect British weather, events like this could become more common.
uncertain
events → grow → this
Experts say the phenomenon is now pushing into unprecedented territory, with vast swathes of the planet forecast to experience unusually warm conditions as the Pacific Ocean releases enormous amounts of stored heat.
asserted
Ocean → say → heat
Professor Adam Scaife, head of monthly to decadal prediction at the Met Office, says he has 'never seen an El Niño signal this intense in our forecasts'.
asserted
he → say → forecasts
While El Niño doesn't directly affect British weather, experts say warm ocean temperatures in the Pacific send 'waves' rippling through the atmosphere.
asserted
temperatures → affect → atmosphere
These waves push the world's most powerful weather systems – including the jet stream – off their usual course, wreaking havoc on Britain's winter weather.
asserted
waves → push → weather
El Niño is expected to bring wet and windy weather this autumn and early winter, with an increased likelihood of storms
Forecasters expect Super El Niño to peak in December and remain strong into the spring of next year; this is currently forecast to be the strongest El Niño on record
According to Uswitch, almost four million adults in the UK lost their broadband connection because of a storm, flood, or severe weather in the past year.
uncertain
adults → expect → year
In rural areas, the effects are even more severe as power grids rely on fewer connections in closer proximity to trees, with one in eight adults experiencing a storm-related outage.
asserted
adults → rely → outage
While some blackouts are brief, the majority leave homes in the dark for several hours.
asserted
majority → leave → hours
Of those affected by outages last year, two-thirds – or 17.6 million people – said that they were cut off for three or more hours.
asserted
they → affect → hours
When large storms strike, huge swathes of the country can be affected, meaning that it takes even longer for power companies to restore connections.
asserted
companies → strike → connections
In 2021, for example, Storm Arwen left over one million homes without electricity.
asserted
Arwen → leave → electricity
Of those, Ofgem, the national energy regulator, found that 400,000 customers were without supply for more than three days, and nearly 4,000 were off supply for over a week.
asserted
4,000 → find → week
Ofgem also found that the majority of the outages were triggered when strong winds blew trees and branches into power lines.
asserted
winds → find → lines
In their report on the outages, Ofgem wrote: 'Severe weather events are likely to become more common as the effects of climate change are felt, so it is imperative that all DNOs [Distribution Network Operators] are well prepared.'
asserted
DNOs → write → change
In 2021, Storm Arwen left over one million people without power, including 400,000 people who were in the dark for over three days
El Niño is part of a natural weather cycle, in which the trade winds that normally carry warm water westwards from the Pacific towards Australia slow or even reverse.
asserted
that → leave → Australia
This leads to a buildup of warm surface water in the Equatorial Pacific, off the coast of South America, which raises the global average temperature and disrupts global weather patterns.
asserted
which → lead → patterns
This winter, experts predict the jet stream will send storms towards the UK along powerful currents of fast-moving winds.
asserted
stream → predict → winds
Will Lang, chief meteorologist at the Met Office, previously told the Daily Mail: 'El Niño conditions increase the chance of storms in late autumn and early winter.'
With that increased risk of stormy weather, comes a higher chance of widespread power cuts and broadband outages.
asserted
chance → tell → cuts
Britons have already been warned to expect large storms this autumn and winter, with the Department for Environment, Food and Rural Affairs urging people last month to 'store a bit of food that can keep you going for a while'.
asserted
that → warn → while
But now, Uswitch says that a charged mobile phone and a backup 4G or 5G router may be just as important for keeping you connected to friends, family and help in case of an emergency.
uncertain
phone → say → emergency
