RED pollution advisories indicate that either current air quality is poor or conditions are expected to worsen later in the day or the next day. Red advisories trigger mandatory wood burning restrictions and voluntary driving reductions. 
BLUE pollution advisories indicate that air quality is good or moderate and no restrictions are required while the advisory is in effect.
