A Saharan dust cloud is set to bring vibrant sunsets and potential 'blood rain' to the UK as fine particles travel thousands of miles from North Africa. The displays could turn skies deep orange and gold, while warm air may push temperatures to 19C in southern parts of the country.
The Met Office said the colour visible in the sky depends on the amount of dust in the atmosphere. 'Blood rain' occurs when high concentrations of red-coloured particles mix with water droplets, but this time concentrations are expected to remain relatively low, meaning rainfall itself is unlikely to appear noticeably red.
Instead, a light film of yellowish or brownish residue may be left on surfaces after showers. People might also notice a light coating of dust on windows and vehicles, as well as slightly reduced visibility at higher altitudes. The Met Office advised those planning to wash their cars to wait until the end of the week.
No significant health impacts are expected, though those with respiratory sensitivity may notice an increase in airborne dust. Sky News weather presenter Jo Wheeler said the display would be noticeable, with hazy skies and vibrant orangey sunrises and sunsets. She noted that Saharan dust is not rare, but this event is fairly potent, driven by Iberian storm Regina and high pressure moving eastward from the UK.
The impacts are most likely today and tomorrow, with Europe expected to be more affected than the UK due to distance from the source.
