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.
Yeah I remember one year where it was so bad in Seattle you couldn’t see across Elliott Bay in Seattle to view either Bainbridge Island or West Seattle. When a ferry or water taxi would get even like 1/3 of the way across the water it disappeared into white space. The sun was blood red for 2 weeks. Just insanely creepy.
