Smoke continues from Pacific Northwest wilfires; Hurricane Irma movies towards Florida

Air quality was very bad today, with a lot of Code Purple (Very Unhealthy) levels in the Pacific Northwest region, with lots of Codes Red, Orange, and Yellow (Unhealthy, Unsafe for Sensitive Groups, and Moderate, respectively) levels in the same area (AirNow, top left). This elevated PM 2.5 was due to the ongoing wildfires in the Pacific Northwest area, mostly in Idaho and Montana. One of the largest fires in the area, the Saphire Complex fire in Montana, currently spans over 40,000 acres and counting (InciWeb). The smoke coverage in this area can be seen in NOAA's HMS map, top right, which corresponds to the PM 2.5 coverage discussed earlier.
Ozone levels, however, were mostly good today, with mostly Code Yellow levels being seen in the Pacific Southwest, the Rocky Mountain States, and the Plains States (NOAA, bottom left).
Hurricane Irma continues to move towards Florida and the rest of the Southern East coast. It is currently moving towards the Turks and Caicos Islands. Part of the hurricane was captured in NASA's satellite images, bottom right.
