SAHARAN dust clouds will bring red skies over Britain today, as sand from North Africa sweeps in.
The sand, which is expected again today, fell in “blood rain”. This is rain that appears red from the high concentration of Saharan dust, which has been whipped up by strong winds and carried for thousands of miles. The dust is mixed into the atmosphere, absorbed by the clouds, and eventually falls as rain.
The Department for Environment, Food and Rural Affairs has warned the South East of moderate air pollution today, but these levels will lower from tomorrow until Friday.
