The talking TV weatherheads are predicting a MAJOR storm for PDX this weekend... 4-6 inches of rain.
They call it the "pineapple express" when these big storms come out of the SW Pacific.
The last such event was 1996, when the Willamette River (thru downtown Portland) had
really major flooding.
Here is a link to a
"real time" weather radar map I use to follow the storm fronts thruout North America.
Easy access to lots and lots of data, graphs, pics, etc.
Right now (6 am PST) the front seems to be reaching Salem, OR... about 50 miles S of Portland.
