12 May PNW Migration Update

The high pressure ridge proved a bit more tenacious than i had anticipated.  I took a quick peak at the radar on Sunday morning.  Migration was a happening event at moderate to heavy levels across the region.  And last night, even with less than ideal wind conditions, birds were heavily on the move again.

The radar in Seattle (KATX) is down.  The operators didn’t leave a message on the NOAA hot line so i’m not sure of the future status.  So, we’ll take a look to the south today and put up a loop for Medford (KMAX).  Mainly because the heavy migration through there last night was about as good as it gets in that area.  Yea!  more birds on the way.
