Larry knows this, of course. But for Washington and Oregon,Monarchs are
uncommon and found, either resident or migrating, mostly East of the
Cascades. One story is that their Milkweed food sources are only found
'East'. As a colorrary, planting milkweed to attract or sustain them is
not really realistic 'West'.
I've lived SE of Portland for 50+ years on a rural property and only seen a
Monarch a single time, long ago, and that was likely in retrospect a
misidentification on my part. There are 'look-a-likes'.
Here are the iNaturalist sightings for Washington State.

Of course, as Larry says, this is indeed a big deal for the eastern 1/2 of
the US
