Flood warnings are in effect for the Pacific Northwest as rain continues to pour into the region. For fun I pulled up our HAMrad II Storm Total Precipitation product (note below), and as of the time of this writing respectable rainfall totals in the 6-8″ range have already occurred.
The state of Washington has several advisories issued associated with the event, including flood warnings, high wind warnings, and associated watches and statements (note graphic below). For updated advisories please see our Advisory Center.
A sample of the flood warnings are included below:

The setup for the southwestern United States has the beginnings of another Santa Ana event as an upper level high from the Pacific Basin will push on shore and basically sit and spin over California by the weekend. NWS offices will likely issue red flag warnings Friday or Saturday as wind gusts increase to ~70mph and relative humidity values plummet to the single digits.
As always stay tuned to your favorite weather outlet, stay informed, and stay safe!
