Stormwalker (Su): The shaman can move through non-magical fog, rain, mist, snow, and other environmental effects without penalty (see Weather). She is never slowed by such effects, and she doesn't need to attempt Acrobatics skill checks to move across such surfaces. She can also move through magical environmental effects that she created. At 10th level, the shaman can see twice as far as normal through environmental effects, whether or not they are magical in nature.
As the title says, does this remove penalties from flying through non-magical wind? I would think RAW, yes, because you've moving through an environmental effect (wind) which would normally have penalties. However, not sure about the RAI, or if I'm reading too much into it.
