The UK is currently facing an extraordinary weather phenomenon with a 600-mile wide “snow bomb” predicted to impact the country, reaching as far south as Cornwall and stretching from John o’Groats to Lands End. This announcement follows rare warnings from the Met Office regarding a “once in 250-year” weather event caused by three simultaneous Sudden Stratospheric Warmings (SSW), marking an unprecedented occurrence in weather patterns. These SSW events disrupt the normal westerly airflow, leading to significant drops in temperature and increasing the likelihood of snowfall and cold snaps across the UK. Cities including Inverness, Aberdeen, Edinburgh, Newcastle, Manchester, Birmingham, Cardiff, and Plymouth are expected to be affected, with the heaviest snow anticipated over the Grampians and Snowdonia. Meanwhile, rain is predicted to follow the snow towards northwest Scotland, Wales, and southwest England.

Temperatures are expected to plummet, with Scotland forecasting conditions between 0C and 1C, and northern England seeing slightly milder temperatures ranging from 2C to 5C. The country is advised to brace for unsettled conditions, with strong winds expected, particularly along the east coast. The Met Office has highlighted the difficulty in predicting accurate snow forecasts far in advance but stresses the importance of staying informed as the situation develops.

This unusual weather event, linked to the rare occurrence of three SSWs this winter—a first since records began—is expected to bring significant disruptions. The Met Office has assured that it can track these events in advance, allowing for preparations to mitigate adverse effects. The last significant SSW event in 2018 resulted in the “Beast from the East” snowstorm, which caused widespread chaos across the UK. While the current forecast does not predict an extreme scenario of that magnitude, the nation is urged to stay prepared and remain vigilant as the weather develops.

In a separate incident affected by extreme weather, Melbourne’s Moomba Parade has been cancelled, and festivalgoers in Victoria, Australia, are advised to return home due to soaring temperatures and fire warnings. The Pitch Music and Arts Festival in Victoria’s Grampians has also recommended attendees depart amid the extreme heat and elevated fire danger. This move to cancel events and encourage festivalgoers to leave sites early has been taken to prioritize the safety of all involved, in response to the heatwave conditions that are also affecting South Australia, Tasmania, and New South Wales.
