An unusual weather phenomena happens in the UK this week, a thin layer of red dust covering cars in southern England was blown in from the Sahara Desert. A storm swept up sand and dust from the western Sahara into the atmosphere, and it then spread into the Atlantic before arriving in the UK, around 2000 miles away in northwest Africa. The airborne particles were blown north to the UK where they combined with the warm air and was deposited during showers.
The Met Office has forecast a ten out of ten level of air pollution for London for tomorrow and Wednesday, with warnings that the dust will this week cause one of the worst smogs of the year.
