We have had something similar for the last few days, due to the wildfires up in the Canadian northwest. It seems that smoke and ash has been carried by the jet stream to a goodly part of the US. It has given, for example, a reddish cast to the moon and, at times, you can even smell the smoke. But it has been nothing like what she has been enduring, nor for so long.We managed to actually talk for 20 minutes at about 3 o'clock this morning. She says that the air quality is somewhat better, although not nearly normal...by a long shot. Apparently, there are particulates in the air, and are ALL OVER THE PLACE. She says it is nationwide, and that some areas are seeing visible particulates, not just her. BUT, very bad in her area.
