Weather Patterns: Prevailing winds play a crucial role in transporting smoke. Northerly and easterly winds often carry smoke from inland fires towards the Puget Sound region. Atmospheric inversions can trap smoke near the ground, exacerbating air quality issues.
Climate Change: Rising temperatures and drier conditions, attributed to climate change, are increasing the frequency and intensity of wildfires, leading to more frequent and prolonged smoke events.

Understanding Air Quality Index (AQI)

The Air Quality Index (AQI) is a tool used to communicate the level of air pollution to the public. It uses a color-coded scale to indicate the health risks associated with different levels of pollution:

Green (0-50): Good – Air quality is satisfactory, and air pollution poses little or no risk.
Yellow (51-100): Moderate – Air quality is acceptable; however, for some pollutants, there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
Orange (101-150): Unhealthy for Sensitive Groups – Members of sensitive groups may experience health effects. The general public is not likely to be affected. Sensitive groups include children, the elderly, and individuals with respiratory or heart conditions.
Red (151-200): Unhealthy – Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects.
Purple (201-300): Very Unhealthy – Health alert: everyone may experience more serious health effects.
Maroon (301-500): Hazardous – Health warnings of emergency conditions. The entire population is more likely to be affected.

The AQI is based on several pollutants, but during wildfire events, the primary concern is particulate matter, specifically PM2.5. These are tiny particles, 2.5 micrometers in diameter or smaller, which can penetrate deep into the lungs and even enter the bloodstream.
