The Maryland Department of the Environment has issued a Code
ORANGE Air Quality Alert Saturday for
the Baltimore City Metro and Annapolis region.

Concentrations of fine particulate matter due to wildfire smoke will
persist at levels consistent with an Air Quality Index of Unhealthy
(Red Alert) to Very Unhealthy (Purple Alert) Friday night into
Saturday morning. Air quality begins to improve Saturday afternoon.

Code Purple and Code Red Air Quality Alerts mean that air pollution
concentrations within the region are unhealthy to very unhealthy for
the general population.

A Code Orange Air Quality Alert means that air pollution
concentrations within the region may become unhealthy for
sensitive groups. Sensitive groups include children, people
suffering from asthma, heart disease or other lung diseases and
the elderly. The effects of air pollution can be minimized by
avoiding strenuous activity or exercise outdoors.
