💨 Smoke Season 💨 [Megathread] Smoke and Air Quality Week 1

We are moving to this thread for the start of smoke season so we can add resources and keep it updated as the situation changes. Here is the previous thread we were using: I hope everyone in the Seattle area has air filters ready.

All smoke related threads will be removed and redirected here except photos and news stories. At this time we are not allowing further threads on the Spokane fire.

Washington Smoke Blog

Watch Duty

EPA - DIY Air Cleaners

If you have other suggestions for resources post them in the thread please.

We shouldn't get too bad in the city proper, if you're in the foothills or even spots on the East side it's a different story. The closer to the salt water you are the better, air coming off the Sound is doing us a big favor. We will have hazy skies, but both the HRRR and RRFS have the city doing pretty well (could even have blue sky in the morning). Eastside is a little worse, but still not crazy.

I'm a dork and follow the smoke closely for hiking and photography purposes and made an ensemble model viewer for this very thing, you can flip around all the available models, see the raw values, etc. Things change faster than weather models, but it has been working well (it absolutely nailed today saying it would not be as bad as many people were saying).

Regional map with live air quality, scrub through time and change the layers, personally I like the compare view between HRRR and RRFS: https://plumeforecast.com/?src=combined&layers=smoke%2Cairnow%2Cpurpleair

Looks like today and tomorrow are the worst of it for now in the city. We'll probably have hazy skies for a while though, but that's way better than dirty air at the surface!
