Smoke, High AOD Levels, and Unhealthy AQI Levels in Florida, Gerogia, and South Carolina

NOAA's Hazard Mapping System (HMS, top) reports smoke over the Gulf of Mexico, Florida, Georgia, South Carolina, and the Atlantic Ocean. The smoke originated from fires in southern Georgia from Honey Prairie, Okefenokee swamp, and northeastern and southern Florida. The smoke from these fires was visible on the MODIS TERRA true color image (middle left). The MODIS Terra AOD map (IDEA, middle right) shows high AOD values due to the smoke in Florida, Georgia, and over the Atlantic Ocean. PM2.5 levels (bottom left, courtesy AIRNow) along the Georgia and Florida coasts reached Code Orange (Unhealthy for Sensitive Groups) with Code Red levels reported in Florida. Code Yellow (Moderate) PM2.5 levels were observed further inland in Florida, Georgia, and South Carolina. Ozone levels (bottom right, courtesy AIRNow) reached Code Yellow and Orange in those three states, as well as in North Carolina.

HMS reports smoke from the fires in Arizona spreading into New Mexico as well as remnant smoke from the fires over Texas and Oklahoma. Smoke from fires in Mexico is also drifting into Texas. The highest PM2.5 levels have been reported in Texas and Oklahoma as Code Yellow. Smoke from the Alberta wildfires was reported by HMS over Oregon, Washington, and Idaho, however PM2.5 levels remained Code Green in these states.

Code Yellow PM2.5 levels were observed in southern California, Great Lakes region, and Northeast. Ozone levels reached Code Orange in southern California, Nevada, Ohio, Wisconsin, and Illinois.
