an astonishing whirlwind of dust observed in the south of the department

The facts took place this Monday, June 7, in Lys-Haut-Layon in Maine-et-Loire. A passerby filmed an astonishing meteorological phenomenon : kind of dust whirlpool, also called “dust devil”.

As reported West France, this phenomenon is similar to a mini tornado. The said passer-by, named Grégory, confided his astonishment to our colleagues: “I thought I saw thousands of birds circling over a field. I stopped and looking closely, I realized that this was like a mini tornado spinning hay. “

The one who was then in his car immediately got out of it, to immortalize the scene. “I felt the wind pick up. It was weird because there was no wind at all. It was moving and it even passed over me, but it was not very violent “, he specifies to the local daily. The previous day, he assures to have observed the same similar one, but this time within his commune, in La Tourlandry.

This phenomenon appears in good weather

Lionel Salvayre, an expert from Météo France, spoke on the question, always with West France. “This ‘dust devil’ type phenomenon is an impressive phenomenon, because it carries a lot of dust, but most of the time, it does not present any danger, he assures. It appears in good weather in a stable or slightly unstable atmosphere. When the sun locally overheats a surface, there can be a rapid rise and rotation of the air. “
