These storm clouds made their way south and were likely related to heavy rainfall and deadly flooding in Yemen on April 13-14, 2016. To the right side of the photo can be seen dark rock outcrops which can rise up to 300m above the surrounding desert floor. Cumulonimbus clouds can rise up to 12km from the ground.
