The snow and blizzards expected to hit Britain due to a phenomenon called Sudden Stratospheric Warming (SSW) will arrive in a few weeks, the Met Office has said, as temperatures remain mild this week.
The forecaster has said that an SSW could hit Britain at the end of February, with maps and separate forecasts showing the first snowfall would arrive on 3 March and spark a 24-hour snow blitz in the North Sea.
