Smoke coverage over Pacific Southwest spreads to plains States

PM 2.5 was very bad again today, with a lot of Code Red(Unsafe) levels of PM 2.5 and Code Orange (Unsafe for Sensitive Groups) being seen in the Pacific Northwest due to the ongoing wildfires in this area (AirNow, top left). The smoke coverage could be seen in NOAA's HMS map coverage, top right, which lines up with the places which were most harshly affected by PM 2.5. The smoke also spread towards the Plains States. The smoke in this area was less dense, but the smoke did still travel there. NASA's MODIS Terra images managed to capture images of the smoke in the Pacific Northwest (bottom left). Ozone, on the other hand, was not very bad, with only Code Orange and Code Yellow (Moderate) levels of PM 2.5 being seen over California.
