A Saharan dust cloud is set to bring vibrant sunsets and 'blood rain' to parts of the UK this week. The fine particles, packed with minerals and sand, have travelled thousands of miles from North Africa and are expected to create striking displays in the sky on Thursday and Friday.
The Met Office said the dust could turn the sky deep orange and gold, particularly during sunrise and sunset. The warm air from North Africa may also push temperatures up to 19C in southern areas. However, the agency noted that the intensity of the colours depends on the concentration of dust in the atmosphere.
'Blood rain' refers to rain that appears reddish when it falls, caused by high concentrations of red-coloured particles mixing with water droplets. The Met Office said that while some dust may settle with rain, concentrations are expected to be low, so the rain itself is unlikely to look red. Instead, a light yellowish or brownish residue may be left on surfaces after showers.
Sky News weather presenter Jo Wheeler said the display would be noticeable in the UK, with hazy skies and vibrant orangey sunrises and sunsets. She added that while Saharan dust is not rare, this event is fairly potent, driven by storm Regina over Iberia and high pressure moving east from the UK.
The dust may also leave a light coating on windows and vehicles, and slightly reduce visibility at higher altitudes. The Met Office said there are no health concerns, though those with respiratory conditions might notice an increase in airborne particles. Car washing is best left until the end of the week.
