Smoke continues to spead across Northwest

Air quality today was not good, mostly because of the ongoing wildfires in the Northwest. PM 2.5 levels mostly stayed in the Moderate (Code Yellow ) levels across the nation, but in the Northwest, PM 2.5 levels rose to Code Orange (Unsafe for Sensitive Groups) and Code Red (Unsafe) levels, as seen in AirNow, PM 2.5 map, top right. The smoke coverage was shown in NOAA's HMS map, top right, which shows that the smoke from the wildfires most likely heavily contributed to the heavy PM 2.5 seen in the Northwest. Images of the smoke were captured by NASA's MODIS Terra satellite, which can be seen in the bottom right.
