13 October 2015 – PNW Migration Update

Another night of heavy, but not widespread, migration across the Pacific Northwest.

The RTX loop shows the continuing pattern of migration concentrated along the Cascades.  Also note the late night, south bound flight out of Nisqually.

The ATX loop shows a heavy and sustained flight across the Straight and onto the Olympic Peninsula.  And another late night flight originating off the southern Sound around Olympia.
