The Atacama Desert in Chile, normally one of the driest places on Earth, was recently photographed covered by millions of pink mallows.  Heavy rains in March provided some areas with up to seven years’ worth of rain in 12 hours.  You can see pictures and read a description here.  While the story does not say so, it is likely that the current El Niño, which was developing at the time the rains occurred, most likely contributed to the rain storms.
