Fine sand from Sahara will travel thousands of miles and when mixed with rain can leave harmless coating on cars
A vast plume of Saharan dust is expected to light up the skies over much of the UK this week.
The fine sand lifted from the deserts of north Africa will travel thousands of miles on warm southerly air currents and is expected to coat cars and other outdoor surfaces, forecasters said.
It will also transform sunrises and sunsets into displays of deep gold, amber and burnt orange.
However, when mixed with rain, it can leave deposits on cars and windows, a harmless phenomenon known as blood rain.
