A rare weather event is affecting 26 regions across the United Kingdom, prompting the Met Office to issue a snow and ice warning. This yellow alert is one of many currently active for today and tomorrow, encompassing parts of northern England and Scotland. In these areas, up to 5cm of snow may accumulate in lower areas, while higher ground could see up to 20cm of snowfall.
The weather warning is set to remain in effect until 2pm today. The Met Office has cautioned that vehicles might get stranded on roads, train services could face delays, and there is a possibility of power outages. Additionally, there is a risk of injuries from slips and falls due to the icy conditions.
Moreover, the warning area is expected to experience “freezing rain” this morning, potentially leading to the formation of “black ice” in certain locations. Individuals are advised to exercise caution on roads and ensure they have necessary supplies in their vehicles, including warm clothing, food, water, a blanket, a flashlight, and an in-car charger.
Freezing rain, a rare form of liquid precipitation that instantaneously freezes upon contact with a cold surface, has been described by the Met Office. This phenomenon, which requires specific conditions, is uncommon in the UK. It occurs when snow passes through warm air, turns into rain, and then encounters colder air, resulting in supercooled droplets with a temperature below zero that freeze upon contact with the ground.
The National Weather Service in the United States explains that freezing rain poses particular risks to bridges, overpasses, and elevated roadways, as well as to tree branches and power lines due to rapid icing. The Met Office highlights the extreme hazards freezing rain presents to aircraft operations.
