Motorists in Bristol are finding their cars covered in dust today, and it's come all the way from the Sahara.
The strange substance is currently covering the country and has even been causing breathing problems for some.
Cars across Bristol have been left covered in the muck, which will have been exacerbated by the recent rainfall.
Saharan dust is a mixture of sand and dust from the Sahara, the vast desert area that covers most of North Africa.
According to the MET office, strong winds in the south have brought the dust from the African desert over the last week, reaching the British Isles today.

Forecaster Bonnie Diamond said: "Dust from the Sahara has been carried across the UK from a south easterly direction.
"It's not uncommon for Saharan dust to reach the UK. How that can affect us is it can cause sunrises and sunsets to look red."
Wind can blow strongly over deserts, whipping up dust and sand high into the sky. If the winds in the upper part of the atmosphere are blowing north, the dust can be carried as far as the UK, explains the MET office.
Once it is lifted from the ground by strong winds, clouds of dust can reach very high altitudes and be transported worldwide, covering thousands of miles. Met Office forecast: Bristol to see four days of rain as humid hot weather ends
Meanwhile, health experts have warned that the Saharan dust could pose a risk to people with asthma as it blanketed the sky, The Mirror reports.
Those with respiratory problems are urged to stay indoors and be aware that the weather situation could worsen their symptoms, such as shortness of breath and wheezing.
Dr Andy Whittamore, clinical lead at Asthma UK, told The Mirror: "Saharan dust could post a serious risk to the 5.4million people in the UK with asthma.
"Toxic air can leave people struggling for breath and can cause wheezing, coughing, shortness of breath and even a life-threatening asthma attack.
"People with asthma must make sure they carry their reliever inhaler (usually blue) with them at all times in case their symptoms worsen."
Cars across the UK have been left coated in a thick film of grime thanks to unusual weather conditions.

People have been taking to social media across the country sharing pictures of their cars and vans after returning to them to find they were not as clean as before.
The grey/brown film has been caused by dust from the Sahara being carried 2,000 miles north on winds caused by high pressure over Scandinavia.
The dust has then fallen across the UK, leaving cars coated in dirt. The Met Office reported it would take 36 hours to pass over the UK.
One resident said: "All the cars in the car park had a light dusting on them, I thought it was strange. And then when I went to the west end to pick up my son from school I noticed all the cars in the area were also covered."
