Note that vertically integrated smoke includes high-altitude smoke so it might not reflect air quality near the surface. Use near surface smoke to see how bad the air will be to breathe. Indeed, it looks like a sea breeze is currently keeping near surface smoke out of some parts of the Bay Area.

There are also several sites that repackage the NOAA smoke forecast data in friendlier (and/or faster loading) visualizations.

E.g., https://www.sfchronicle.com/air-quality superimposes wind, and also toggles between smoke forecast and real time PM2.5 measurements from the PurpleAir sensor network.

They should unhide one of the layers by default.

Yep, everyone I've forwarded it to so far has asked why it doesn't show anything.
