Smoke from Plains States wilfires spreads to Southwest

PM 2.5 levels were mostly good today, except for in the Pacific Southwest region (AirNow, top left). PM 2.5 levels ranged from Code Yellow (Moderate) levels to Code Red (Unsafe) levels in this region, most likely because of smoke that spread from wildfires in the southern Plains States and Mexico. The layout of the smoke can be seen in NOAA's HMS map, top right. This smoke was also captured in NASA's MODIS Terra images, bottom left. In this image, light plumes of smoke could be seen mixed in with some cloud coverage. Ozone levels were more widespread, with Code Yellow levels appearing in the Plains States, the Rocky Mountain States, and the Pacific Southwest.
