06 Mar 2015 — Migration Update

Looks like the birds are enjoying the unseasonal weather as well.  Last night we got our first peak at some rather heavy movement.  Green radar returns for a good portion of the night and more widespread than last night’s assault on Mt Hood.  That assault repeated, but we had heavy movement up the Willamette Valley and into the Puget Trough.

I still think these are staging waterfowl and not vanguard neo-trops.  List chatter is only reporting Turkey Vultures and Rufous Hummingbirds.  Much further south, like Anzo Borrego, Swainson’s Hawks are on the move.

I threw in the Hydrometeor loop today, just to confirm what is pretty obvious, these returns are indeed biological.
