A rare and extraordinary weather event has brought life-giving rain to the Sahara desert, filling lakes and replenishing water sources. Satellite images from NASA show the impact of a cyclone that dumped over 8 inches of rainfall in just a few days, equivalent to an entire year's worth of precipitation. The deluge filled multiple ephemeral lakes in Algeria and Morocco, including the Sebkha el Melah lake, which covered 74 square miles and was approximately 7.2 feet deep.
