A very large plume of thin density remnant smoke is covering most of the Gulf of Mexico. The smoke was produced by the seasonal and agricultural fires in Mexico and Central America. This large plume was seen reaching the edges of Florida around the Gulf and the edges of southeastern Louisiana, as seen i the NOAA HMS image, top left. The southern plains, specifically New Mexico, Texas, and Oklahoma, saw a large area of dust moving through portions of the region (VIRRS satellite image, top right, and MACC AOD image, mid left). The image on the bottom left shows the area of the southern plains affected by the dust. Ozone also affected the Southern US today. The southern Mississippi Valley and southeastern Plains saw elevated levels of Ozone; this was likely due to some of the remnant smoke moving into the area, the winds slowing down, and the temperatures rising, enhancing the production of Ozone in the region. Elevated Ozone levels were also seen in the Pacific Southwest, as seen in the AirNow O3 image, mid right. In spite of all these components that tend to worsen air quality, the vast majority of the US enjoyed good air quality today. However, the regions affected by smoke, dust, and ozone did see a few small patches of moderate, code yellow, air quality, as seen in the AirNow PM AQI image, bottom left.
