Well, it's that time of year again... (Fires were started by the thunderstorms a few days ago.)

Where are the fires? South of San Jose?

Both north and south of us. Smoke probably from the north. Maybe as shown in nitter.vloup.ch/davidbaron/statu… although probably some aren't showing up there yet.

Wow! @ljharb was just telling me about the smoke that suddenly appeared out of nowhere at his house. And that's the Bay area! Crazy town. Hope you all stay safe and healthy. ❤️
