A vast plume of Saharan dust is expected to reach the UK this week, creating vibrant sunrises and sunsets while potentially leaving a dusty coating on cars and outdoor surfaces. The fine sand, lifted from the deserts of north Africa, will travel thousands of miles on warm southerly air currents, according to forecasters.
When mixed with rain, the dust can create a phenomenon known as blood rain, leaving deposits on cars and windows. The Met Office warned: “The combination of warm air and Saharan dust may lead to some dusty deposits on cars or outdoor surfaces as the frontal rain washes the dust out of the atmosphere overnight into Friday.”
Saharan dust is relatively common in the UK when large dust storms in the Sahara coincide with southerly wind patterns. It can also affect air pollution levels, the Met Office noted.
The dust is expected to be in the UK’s atmosphere over the next couple of days and could coincide with the warmest day of the year so far on Thursday, when temperatures may reach 19C in southern parts. More widely, temperatures of 16-17C are forecast.
Honor Criswick, a Met Office meteorologist, said the band of cloud and rain on Thursday could be heavy at times. “There should be lots of long sunny periods until that rain starts pushing into the east,” she added. Friday will be cloudier across much of England and Wales with highs of 11C-12C, while Northern Ireland and Scotland will see more sunshine. The weekend will bring a mix of patchy cloud and sunshine, with highs of 12C-13C on Saturday and 14C on Sunday.
