Households are being urged to stock up on six essential food items this winter, should fears of a bitterly cold, snow-laden season caused by the El Niño weather phenomenon materialise. A polar vortex could unleash colder conditions and even snowfall across the UK this winter, as El Niño drives a chillier season, according to climate experts.
El Niño and the Polar Vortex
El Niño has been a primary force behind this year's sweltering temperatures, with the warming of the ocean's surface having a dramatic knock-on effect on global weather systems, generating far warmer than average conditions. It is thought to have been one of the contributing factors behind the UK's five record-breaking heatwaves this summer.
While nothing is certain as yet, the El Niño weather front triggers shifts in high and low pressure patterns. The strength of a polar vortex - the mass of cold air that ordinarily swirls over the North and South poles - is susceptible to disruption from jet streams, reports the Express. When thrown off course, it can drive freezing air into the US and Europe, sparking a cold snap and snowfall.
Essential Food Items to Stock
Direct Energy advises that households facing the prospect of snow should stock up on non-perishable food and essential supplies in case they are unable to reach their local supermarket or experience a power cut this winter. According to the energy firm, households should make sure they have bottled water as well as these six food items: bread, milk, tinned goods (especially warming foods like soups and stews), snack foods (such as crisps, crackers and cookies in sealed packages), cereal and granola, and dried pasta and jars of sauce.
It is also advised that households have an emergency kit at home consisting of essential items such as a battery or wind-up torch, portable power bank, battery or wind-up radio, spare batteries, a first aid kit, hand sanitiser and wet wipes, bottled water, non-perishable food, and baby supplies.
Expert Warnings and Government Guidance
According to experts, El Niño could interact with the polar vortex this winter. "The polar vortex above the Arctic is linked to the jet stream. Both can be impacted by El Niño, and bring about changes in our weather patterns", Darryn Waugh, a professor in Earth and Planetary Sciences at Johns Hopkins University, told USA Today.
The Met Office said: "Through the latter part of the winter, following a peak in El Niño, the stratospheric polar vortex (SPV) can become weaker, leading to an increased chance of Sudden Stratospheric Warming (SSW) events unfurling, increasing the potential for cold weather." However, significant as El Niño is, it is important to emphasise that it alone does not determine precise weather patterns and other outcomes remain possible.
The Government has unveiled a nationwide campaign to help Britons understand the appropriate provisions, essential items to store in their cupboards, evacuation routes, and emergency contacts to have. Security Minister Dan Jarvis said he wants to ensure communities are as resilient as possible as he admitted there are likely to be "a number of challenges" facing the country this winter.
According to GOV.UK, a significant El Niño is likely to occur towards the end of 2026, "with some forecasts predicting the strongest event on record". "There are clear signals indicating further development of the current El Niño event", with its peak expected in December 2026.
In its online guidance on preparing for snowstorms, Direct Energy stated: "After heavy snowfall or blizzard conditions, you could find yourself snowed in for days." Getting cut off from your local grocery store could be made worse by a prolonged power outage, which would leave you with just a few hours to enjoy the remaining contents of your fridge safely. But if you stock your pantry with filling shelf-stable foods, you won't go hungry while waiting for the snow to be cleared.
