Wow! On par with the heaviest migration this season. Last night’s flight was heavy, widespread, and continuous. RTX was just rocking. The radar out of Seattle (ATX) was really jamming in the south of it’s range in the Puget Trough. We’re still seeing decent flights across the Straight as well, not as dense but still in the green.
Take a look at Paul’s archived National Composite (here) and you’ll see that the PNW was the migration hot spot last night – that doesn’t happen very often.
