Hello.  I read this post and also the one linked to it which went over the wet winter of 2016-17 in California.  And, based on that, I had four questions:

1. How strong is the La Niña this year compared to a normal one?  That is, is it normal, strong, or weak?

2. Does it appear to be weakening or strengthening?  

3. Any idea what else has been going on in the atmosphere to push these atmospheric rivers into California over the past few weeks rather than further north? 

4. When a La Niña ends or is ending, do weather impacts from that tend to be observed simultaneously across the U.S., or do its impacts tend to be observed earlier in some areas than others? 

Thank you for reading this, and I look forward to hearing from you.
