The smoke from all the persistent fires combined with regional scale pollution and increased temperatures created very hazy conditions in the entire U.S east of the Mississippi river. Aerosol optical depth levels were over one for both MODIS AOD and GOES GASP, and were especially high over Michigan. Fine particle concentrations were moderate to unhealthy.
Further south, fires continued to burn in Mexico and Central America. The NOAA Hazard Mapping System exaggerates the smoke and fires a little, but shows the extent of the smoke in the western Gulf and the location of the fires.
