Luxembourg braces for the arrival of warm winds from North Africa on Tuesday, heralding a fresh wave of desert dust blanketing Europe. This atmospheric event may give rise to the so-called "blood rain" phenomenon.

A new cloud of Saharan sand is set to disperse across eastern France, the Benelux countries, south-west Germany, Switzerland, and Italy, as reported by Meteolux. Originating from the Sahara Desert in North Africa, the world's largest sand desert, this migration of sand particles is a seasonal occurrence, typically observed during spring and autumn.

Residents in affected areas should anticipate overcast skies and heightened levels of particulate matter during this period. Motorists are advised to exercise caution when cleaning vehicles, as the fine Sahara sand may settle on paintwork and windows. Despite these conditions persisting until Thursday, meteorologists anticipate relatively low concentrations of dust in the atmosphere.

In addition to the dust phenomenon, meteorologists forecast the possibility of "blood rain," an occurrence resulting from the interaction of precipitation with Saharan sand particles. This event may lead to the deposition of sand on the ground.
