The Air Quality Index in my town is currently 260 (very unhealthy) due to a surge in wildfires in western Canada and the northwest US. There are additional smaller fires not shown on this map at this zoom level.
From the interactive map it looks like the worst air in the world right now.
I’m glad I don’t live in central Washington anymore. I still remember a few years back I was stopped at a sign and the smoke was so thick I could watch the dark red sun setting behind the even thicker smoke to west at 4 in the afternoon. It was surreal.
