‘Blood rain’ and fiery sunsets as Saharan dust sweeps UK

When Saharan dust mixes with rain, it creates what is commonly known as blood rain.

Tiny dust particles suspended in the atmosphere are captured by raindrops and deposited on surfaces, leaving a fine, sandy, reddish-brown residue.

Cars, windows, garden furniture and other outdoor items can become noticeably coated and sometimes require washing to remove marks.

Parts of England and Wales are expected to experience the most significant impacts as dust concentrations are forecast to be highest due to the prevailing winds and the location of the high pressure system.

Even in lighter dusty areas, a faint film may appear on surfaces after rain.

Despite its dramatic name and unusual appearance, this type of rain is completely harmless.

The dust does not pose any health risks to most people, and any impairment is largely cosmetic.

This is a natural consequence of Saharan dust being transported long distances by the atmosphere and offers a rare and sometimes complex reminder of how far-reaching global weather systems can be.
