I don't know if any cachers in the area have been personally affected by the fires, but aside from smoke bugging my lungs, the only issue I have is I think one of my caches is in an evacuation area.
I hope geocaching is never responsible for one of these. We were at a cache recently and removed some matches from the container.
If anybody's looking to cache in the area, here's an unofficial map showing some of the burn areas and the evacuation alert/order areas
