The Air Quality Index shot above 400 in some places (including NYC), well into the danger zone for human health. Thankfully, shifting air currents and weather improved air quality over the weekend. Already Canadian smoke is dipping back down into the lower 48 while, of course, continuing to inundate parts of Canada as well. In both these instances, the smoke has hovered relatively high up in the atmosphere, causing minimal air quality impacts lower down. The summer is just getting started, and this summer is only the beginning.
