Met Office Rejects Super El Niño Snow Claims Across UK

Claims that a Super El Niño event will bring a major snow outbreak to the UK have been challenged by the Met Office, which said the climate pattern may influence weather probabilities but does not confirm a severe winter scenario.

The current El Niño event is developing in the Pacific and has been described as unusually strong, but the Met Office said its effects on Britain are less direct than in other regions. The agency said forecasts indicate wetter and windier conditions rather than an immediate extreme cold event.

A research paper from the US government NOAA Chemical Sciences Laboratory examined links between El Niño and the polar vortex, a circulation of winds around the North Pole that forms each winter.

"tends to promote the breakdown of the polar vortex, especially in late winter" said NOAA Chemical Sciences Laboratory research paper.

The Met Office explained that any polar vortex changes would affect probabilities rather than guarantee specific outcomes for the UK. The organization also linked possible late-winter changes to Sudden Stratospheric Warming events.

"Later in winter, following the peak of El Niño, the stratospheric polar vortex can become weaker," said the Met Office.

"This may raise the chance of Sudden Stratospheric Warming events, which can increase the potential for cold weather." said the Met Office.

Nicola Maxey, a Met Office spokesperson, said El Niño remains only one factor among several that influence British weather. She said the event generally has a more indirect effect on the UK compared with other parts of the world.

"While El Niño is one of several factors that can influence the UK’s weather, its impact here is less direct than in some other parts of the world." said Nicola Maxey, Met Office spokesperson.

Maxey added that stronger El Niño conditions can increase the likelihood of unsettled weather patterns during late autumn and early winter, while not determining exact conditions.

"A strong El Niño can increase the likelihood of wetter and more unsettled conditions during late autumn and early winter, but it does not determine exactly what weather the UK will experience, nor does it automatically lead to an increase in extreme weather events." said Nicola Maxey, Met Office spokesperson.

Ilan Kelman, Professor of Disasters and Health at UCL, said El Niño could be associated with broader seasonal trends, though outcomes remain uncertain.

"There’s nothing definite, but in general we would expect a milder, wetter, and stormier autumn, a colder winter, and then a possibility of a hotter summer next year," said Ilan Kelman, Professor of Disasters and Health at UCL.

Some reports suggested preparations for a "551-mile wall of snow", but the Met Office said there was no forecast showing such an event. Government advice on storing supplies relates to wider resilience planning, including concerns such as "hybrid war", rather than an expected snowstorm.

Reports of temperatures "plummeting" were also disputed by the Met Office, which said cooler conditions were expected but not an exceptional cold spell.

"Daytime values are expected to be close to or a little below average" said the Met Office.

"Friday’s temperatures should be mostly near average and could sit slightly above normal in the south and east. Saturday is likely to be rather cool in places, with blustery winds, sunny spells and scattered showers. This is a recognisably autumnal pattern rather than an exceptional cold spell." said the Met Office.

The Met Office said longer-range forecasts pointed toward increased chances of wind and rain later in autumn and early winter rather than widespread snowfall.

"Our current longer-range outlook indicates an increased likelihood of wetter and windier conditions, particularly later in the autumn and early winter." said Nicola Maxey, Met Office spokesperson.

The near-term forecast described by the Met Office includes rain moving across England and Wales, showers in northern areas, and cooler but typical autumn conditions.
