The rain rate has really picked up around the area..take a look at the latest radar (9:33 PM)...lots of yellow (heavy rain). You can see the rainshadow over central Puget Sound--but it has really attenuated. Another rainshadow east is of Vancouver Is. There is heavy precipitation over the mountains...but the radar beam is blocked so you can't see it.
The infrared satellite image shows the pineapple express plume of moisture stretching far back into the Pacific. The next 24-h will bring heavy rains to the mountains..with the moisture plume slowly moving south.
A number of mountain sites have already gotten 2-4 inches. And this is just beginning.
The NWS has a nice hydrology site for those who want to see current river levels and what their models are predicting:

Or check out the UW Hydrology page:

Both are going for major flooding....
