This is the first of several El Nino - driven storms that are in the queue
5 Jan 2015 0.75" (This was previously reported as 1.75", but I think that was an error. Title and this line fixed 1/13/16.)
Historically, the median rainfall during all of January is about 1.5", additionally, the historic median cumulative rainfall at the end of January is 3.8".
We're definitely headed for the predicted high rainfall winter given that nearly the entire month still lies ahead.
