I just got back from a walk around the block, specifically to listen for migrating Greater White-fronted Geese. They were streaming overhead, flock after flock, non-stop.
Which brings us to today’s radar loops. The RTX loop is very interesting. Shortly after sunset there was a small but noticeable flight out of the area for about an hour or so, and then — nothing of note. That is until around 2:30 AM (PDST) and BOOM! The sky is just filled with returns up to the 30 dBZ level. I suspect a majority being Greater White-fronted Geese.
I also threw in the Gray’s Harbor (LGX) loop because this is the largest sustained flight i’ve seen this season from there.
Note the wind map and the favorable winds out of the NNW.
