Sounds to me like she's about to shed...and it's gonna be a rough one. It will likely come off in a million little pieces and she may have a lot of stuck shed afterward.
I would make sure the humidity is increased, although it is probably too late for that effort to make much difference. Let her get as much of it off on her own as she can without bugging her. And THEN, if she does, indeed have a lot of stuck stuff...then I'd soak her and help her off with the rest of it.
