Meteorologist sheds light on the phenomenon known as the Beast from the East as the UK experiences a sharp drop in temperatures, with parts of the country reaching as low as -7°C overnight. Weather and health warnings have been issued, with a yellow cold weather warning in effect, posing risks of ice and snow in certain areas. The UK Health Security Agency (UKHSA) has issued yellow cold health alerts for regions across England, including the North East, North West, Yorkshire and the Humber, and the South East starting from Friday at 9am until Tuesday at 9am.
Stephen Dixon, a spokesperson for the Met Office, shared insights on the current weather conditions, mentioning the potential for temperatures to plummet to as low as minus 7°C in rural parts of Scotland. Southern areas are also expected to experience sub-zero temperatures over the weekend, with rural parts of southern Wales likely to see temperatures as low as minus 4°C. This sudden cold snap can be attributed to a polar vortex, as explained by John Griffiths, a meteorologist with environmental monitoring experts KISTERS.
Griffiths elaborated on the meteorological phenomenon, stating that the term Beast from the East is often used to describe the occurrence when easterly winds bring cold air from the east, leading to icy conditions in the UK. This is typically a result of disturbances within the polar vortex, causing west-to-east winds to weaken and allow cold air from Siberia to move across Europe and the UK. The expected easterly cold weather is forecasted to persist throughout the middle of the month, potentially bringing significant snowstorms, particularly affecting regions like Scotland and Kent.
Advice from meteorologists highlights the importance of staying informed through the Met Office and weather warnings, as heavy snowfall can disrupt travel. As temperatures are anticipated to drop further, precautionary measures are advised, with the possibility of seeing snowfall in parts of south England and south Wales. Saturday is expected to be mostly overcast, with rain in southern regions, while Sunday may see showers but with comparatively drier conditions. Additionally, wintry showers are a concern for Monday, subject to monitoring by the Met Office.
The term Beast from the East refers to a weather phenomenon where cold air originating from Siberia moves towards western Europe, leading to extreme cold temperatures, heavy snowfall, and strong winds. This occurrence is often caused by high pressure over Scandinavia pushing frigid air from Russia into regions like the UK. Notably, one of the most significant Beast from the East events took place in February–March 2018, resulting in heavy snowfall, icy conditions, and widespread disruptions across the UK and Europe.
During this period, the UK experienced severe winter weather, with temperatures dropping well below freezing, significant snow accumulation, and transportation systems heavily impacted by the adverse conditions. The convergence of the Beast from the East and Storm Emma exacerbated the situation, causing blizzards, freezing rain, and strong winds, resulting in multiple fatalities and substantial economic losses. The notable effects included travel disruptions, school closures, and challenges for emergency services in reaching affected areas.
Overall, the phenomenon of the Beast from the East underscores the unpredictable nature of weather patterns and the importance of preparedness in dealing with extreme conditions. As the UK braces for colder temperatures and potential snowfall, vigilance and adherence to weather advisories remain crucial to ensure the safety and well-being of individuals across the affected regions.
