This week the UK was told to brace itself in preparation for #Snowmaggedon to sweep across the country.
As temperatures plummeted the Met Office issued yellow and amber warnings across the UK.
Monday and Tuesday saw widespread snow coverage and it wasn’t long until Cornwall plunged into chaos.
But why has this phenomenon happened? Why is the South West, so often neglected of the celebrated ‘snow day’, now feeling the impacts of a snow storm?
Dan Holley, Associate Fellow of the Royal Meteorological Society told Truthfal, “Storm Emma is primarily affecting South West England and South Wales because these are the areas with closest proximity to the area of low pressure responsible.
“Because the storm is slow-moving, bringing strong southeasterly winds, combined with a very cold air mass covering the British Isles, this is allowing snow to fall for several hours and pile up on southeast-facing up slopes.”
“Elevation plays a key role in how much snow you receive, in fact the Moors of the South West see more snow than many parts of South East England and East Anglia.”
“However, one of the main reasons for the North and East getting more snow is because cold air masses in the winter typically come from the North or the East, and so naturally it is these parts of the UK that generally have a better chance of snow.”
He added, “The West and South West is more prone to milder air from the Atlantic, making conditions, at times, more marginal for snow away from the high ground of the Moors.”
So ‘Storm Emma’ or Snowmageddon seems to be a one of, and this unusually positioned area of low pressure has caused no end of troubles for schools, universities and businesses across the UK.
The snowfall has been some of the worst in over 30 years and Holley predicts it could be another 30 before the county sees snow like this again.
Looking ahead to the weekend, the worst is over for Cornwall with the weather forecast predicting rain with highs of 9°C in the coming days.
