Met Office warns of record-breaking El Niño with uncertain UK impact

Summarised from 2 outlets · Updated 9 Oct, 12:44 · Archive

The Met Office has warned that the developing El Niño is the largest in recorded history, though its effects on the UK remain uncertain. The weather phenomenon, which occurs in the tropical Pacific, affects temperature and rainfall patterns worldwide, but the UK's distance from this region means impacts are harder to predict.

El Niño can increase the likelihood of wetter, stormier and generally milder conditions in the UK during late autumn and early winter. Later in winter, following the peak of El Niño, the stratospheric polar vortex can weaken, which may raise the chance of cold weather events. However, Grahame Madge of the Met Office stressed that these are shifts in probability rather than guarantees, and determining the potential for specific parts of the UK such as Lancashire is beyond current forecast capabilities.

Madge said: 'There are known teleconnections for the UK including a trend towards a wetter and windier late autumn and winter period and the potential for a colder end to winter. However, although these connections may be a factor for UK weather over the next six months, they are by no means guaranteed.'
