Just looking at what is coming at us at THIS LINK (click on 'Loop 12) makes prior storms pale in comparison. There is one bright side to it - for the time being it looks like this will sail through rather rapidly, rather than sitting on top of us for days or hours within days.
Forgot to say - look at the monster-amount of rain just west of Hawaii - all of it (or most of it) appears headed California way pretty fast...
Thanks,...looks like the really heavy stuff is up toward San Francisco.
