wildfireSmokeIndex0: No risk.
1: Minor risk - Concentrations of particulate matter may increase due to nearby wildfires, but should be of little risk to the population.
2: Moderate smoke concentrations possible - This area may experience increases in PM2.5 concentrations that could be risky to those who are unusually sensitive to pollution.
3: Significant smoke concentrations possible - Particulate matter concentrations could be significant enough that those at high risk could have adverse health affects.
4: Major smoke concentrations probable - This area is at high risk of smoke concentrations that could have adverse affects for the general population. Those in unusually sensitive groups should take precautions.
5: Extreme smoke concentrations likely - PM2.5 concentrations are likely to be high enough that everyone is at risk for health effects due to the poor air quality.
