Possibly!  As Emily documented earlier, the October-December La Nina average (the 3mo. season nearly completed) doesn't have a lot of drier than average conditions over California. (more wet than dry).  It's really during the later winter and spring when the La Nina signal starts to emerge.  See the January-March La Nina average, which has more of a tendency toward drier than average conditions over California.  As always, official climate outlooks are probabilistic.
