The ADEC issued an air quality advisory today due to the eruptions of Mt St Augustine.
According to the NOAA HYSPLIT trajectory, the ash is expected to advect southeastward.
It is still very cloudy in the north and the east. The AQI is good in most of the country (EPA AirNow). A site in southern California is under code orange which means that the PM2.5 concentration is higher than 40.5 ug/m3. Today's HMS map shows that there are some smoke plumes in Texas.
