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.

The article doen't indicate how strong these dust devils are, but I sure hope that one doesn't damage Curiousity.

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.

Believing when there is no compelling evidence is a mistake.  The idea is to withhold belief until there is compelling evidence and if the universe does not comply with our predispositions, okay, then we have the wrenching obligation to accommodate to the way the universe really is.  - Carl Sagan

i remember reading that these dust devils are really weak, if you experienced one it would be like someone blowing on you. so not even a light breeze.
