Ireland is set to be hit with massive amounts of Saharan dust this week which will leave the capital and beyond with dusty skies.
The 'outbreak' - as described by Severe Weather Europe - will see a new and very dense wave of dust being pushed into the UK and Ireland on Tuesday.
The weather event is caused by a "broad cutoff upper low over the Iberian peninsula and the western Mediterranean."
These low-level winds are pushing northwards and firing the thick wave of dust from Algeria across Europe.
The dust reaches the ground through raindrops - as they fall they collect particles of dust and when the raindrops evaporate, they leave behind a layer of dust.
People who suffer from respiratory problems are told to be aware of the rising level of pollution over the next few days.
The event is set to last for "several additional days, with models indicating thick dust over the UK and Ireland on Tuesday and Wednesday".
Severe Weather Europe said that although this type of weather event is not rare, the current one is "very extensive and is producing major dust loads".

As previously reported by Belfast Live, it was warned that dust from the Sahara Desert brings potentially dangerous levels of air pollution to Ireland and the UK.
In February, moderate and “possible” high levels of pollution were forecast according to the Department of Agriculture, Environment and Rural Affairs.
They said that the “symptoms of people with lung or heart disease may worsen” in these conditions.

A spokesman said at the time: “These pollution levels are the result of the weather conditions we are currently experiencing, with light winds, which can lead to the build-up of local emissions from vehicles and home heating. There may also be a more widespread component of pollution from continental sources and Saharan dust.
“During periods of High Air Pollution the symptoms of people with lung or heart disease may worsen. Healthy people are unlikely to experience any ill effects.”
