Data collected by the rover's meteorological instruments indicates significant dust devil activity.
BBC News said:
Curiosity has spent several weeks now parked at a sand dune dubbed "Rocknest", where it has been testing procedures for digging up soil samples and delivering them to the robot's big internal laboratories.
Dust won't do the solar panels any good. They should have built in a way of cleaning the dust off them. I'm presuming they didn't.
That isn't a problem on Curiosity because it doesn't use solar panels, it uses a thermoelectric radioisotope generator thet utilizes the heat from decaying plutonium to charge a battery through thermocouples. This sysetm provides a steady amount of power regardless of environmental conditions and also warms vital instruments throughout the rover.
