Via Laura Paddison in cnn.com: Striking images from the Sahara Desert show large lakes etched into rolling sand dunes after one of the most arid, barren places in the world was hit with its first floods in decades. The Sahara does experience rain, but usually just a few inches a year and rarely in late summer. Over two days in September, however, intense rain fell in parts of the desert in southeast Morocco, after a low pressure system pushed across northwestern Sahara. Preliminary NASA satellite data showed nearly 8 inches of rain in some parts of the region.
