The sun sets over Wright Patman Lake amid a recent cloud of Saharan dust. A second wave of the African plume has hit the area in as many weeks, though the National Weather Service says it is less dense than the previous "Godzilla" cloud that caught the attention of astronauts aboard the International Space Station. The plume, known as the Saharan Air Layer, forms each year over the Sahara Desert before moving across the Atlantic in waves between mid-June and mid-August, according to the National Oceanic and Atmospheric Administration.
