Snow sprinkled the orange sand dunes of Ain Sefra, northwestern Algeria on Sunday, creating a rare and spectacular sight, more reminiscent of Mars than Earth.
The snowfall was caused by the large cutoff upper low over western Mediterranean, which also influenced northern Algeria. The snow was visible also in satellite imagery, standing out in the orange desert surface.
