The UK is experiencing significant disruption due to heavy snow and freezing rain, prompting amber weather warnings across northern England, the Midlands, and Wales. Accumulations of 20-40 cm of snow are expected, leading to suspended flights and travel chaos. Power outages are reported in several regions as local authorities advise cautious travel. Further adverse weather is anticipated, with milder temperatures later this week potentially causing flooding from melting snow. The Royal Meteorological Society warns of icy conditions as rain interacts with colder temperatures.
