NOAA HMS (top left image) reported the presence of remnant smoke across southwestern Northwest Territories, northeast British Columbia, Alberta and west-central Saskatchewan. This area of smoke is believed to also be associated with the wildfires southwest of Great Slave Lake.In southern Texas there is an area of aerosols, believed to be smoke mixed with haze/pollutants. Also, fires located south of the border in eastern Mexico are contributing to the high AOD readings (top right image) along the Gulf of Mexico. This may be impacting the PM2.5 AQI levels in southern Texas as concentrations reached Moderate levels (PM2.5 AQI animation below)
Code Yellow to Orange AQI levels for ozone and PM2.5 were reported today for the state of California, as shown in the AQI animations below. The Great Lake states experienced Moderate PM2.5 concentrations.
