Bad air quality data for a whole region
It looks like this is what happens when a single source of weather data gets well and truly confused. For reference purposes, out the window right now, it does not look like Mordor here in the Bay Area. But, the vendor that feeds data to Apple thinks there's something evil going on, so all of the iOS devices think that, too.
I saw this on my stuff a few minutes ago and went digging. Here's what the vendor ("BreezoMeter") thinks is going on for this whole area right now:
I wonder, do they only have a single sensor here, and did someone back up a massive truck to it? Or maybe someone found it and decided to "roll coal" to see what it would do to all of our devices.
Well, there you go. According to them, we are in hell.
I just hope this isn't a prediction for the upcoming fire season.
