“Everyone was stunned to see snow falling in the desert, it is such a rare occurrence,” Bouchetata told the Independent. “It looked amazing as the snow settled on the sand.”
Bouchetata added that the snow lingered a day before melting.
Ain Sefra, founded in 1881, has a population of about 35,000. It’s in western Alegria about 28 miles east of the border with Morocco.
While it has a blistering hot summer climate, with average highs around 100, it’s somewhat chilly during winter. Perched at an elevation of more than 3,500 feet (1,078 meters), its average December high temperature is only around 50, with average lows in the upper 30s.
A weather map analysis from Monday shows that temperatures in the area were roughly 10 to 15 degrees colder than normal when the snow occurred.
An unusually strong area of low pressure at high altitudes was passing over the region, which forced the air to rapidly rise and cool, enabling the exceptionally rare snowfall.
The snow in the mountains adjacent to Ain Sefra was visible from NASA’s LandSat 7 satellite on December 19. The scene below is from southwest of Ain Sefra:
