Take a look at the 24h precipitation ending 5 PM Sunday and Monday (below). Some mountain areas will be getting 2-6 inches, with moderate rain even over the lowlands (particularly late Sunday and early Monday).
And what about winds? Look at the pressure forecast for 11 PM Sunday night. With an intense low far offshore, we still have very large pressure differences in the coastal waters and over NW Washington--which means strong winds.
The wind forecast for the same time shows 45 kt sustained water in the coastal waters and 35 kts over NW Washington. Gust could be considerable larger. Time to batten down the hatches and enjoy some storm watching! And the models are showing significant snow above 4000 ft this week.
