They said that spending the day outside is like smoking 8 cigarettes.

Maybe I'll go for an unhealthy ride this evening. It may even get to "unhealthy for sensitive groups" around 6:00 -- and then back to hazardous. -- Jay Beattie. |

Since my lungs have had enough for one lifetime I won't ride until we have descent air quality. Maybe an easy ride this weekend. |

Definitely changes fast. aqicn.org (currently) doesn't even try to forecast more than three days in advance for Salem, and only seems to update the forecast once or twice daily. Consequently, I've taken to assuming the worst rather than basing too much on the forecast. So far, I've been right. Yesterday's forecast for *now* was around 150, actual is 412 ("Hazardous"). I don't blame them; I suspect their models are essentially weather models; what we have going on right now is not exactly "weather." I think the fires even screw up the wind pattern forecasts.

But here it's all in the upper atmosphere. No breathing problems. Glad it's not down on your level where you have to breathe it. Just to be fussy, I think you're seeing southern California's smoke, based on a satellite photo I've seen (band of smoke direct from So Cal to upper midwest). For a while ours (Oregon) was going out to sea and building up quite a "reserve" so that when the wind reverts to a more normal westerly direction, we'll still have smoke for a few days. Oh fun. Current local AQI: 394; Over 300 is "Hazardous." Mark J. |
