There were some amazing variations and storm totals in the precipitation...
Take a look at the table below from the National Weather Service.
At the UW we had 1.4 inches for the entire storm (last 48h), and Everett had even less
...1.04 inches. Sea Tac had 3.42 and Olympia 6.03. That's a rainshadow. The most
amazing amounts were in the mountains where some locations had 10-15 inches.
Heavy precipitation was the big reason for the flooding, but the melting of lowland snow
was also important. This is also true of some other big flood events like the Feb 1996
flood, which was even more damaging than this one. High mountain snow actually works
against flooding, since the snowpack can absorb some of the water, where it can refreeze.
Interestingly some of the high mountain sites showed very little change in snow water
equivalent...the amount of water in the snow...during this event. But the snow depth can
change dramatically...at Snoqualmie pass the snow depth has gone from 78 to 43 inches in
two days.
Right now have pro frontal conditions with showers in the mountains and a Puget Sound
convergence zone north of Seattle (see radar). Tomorrow will be dry and temperatures
40s. Some showers over the weekend...and some amazingly dry conditions the middle of
next week.
