Well that was quite a night! I, for one, am tired of this wind and rain and will be super happy to see some sun.
But did you know that in the winter of 1861-62 California was hit with a 43 day storm that put parts of it under water for 6 months?
These two photos are of Sacramento during that flood.
Scientific American has an article about it here. And just Googling "California flood 1861" will bring you lots more information.
