An air quality advisory is now in place due to high concentrations of fine particulate matter that are expected to persist until weather conditions change.
The advisory was invoked Tuesday, shortly before 4 p.m.
Officials said the event is a particular concern for people with underlying health issues as well as pregnant women, infants, and older adults and they're urged to avoid strenuous activity while the advisory is in effect.
Also open burning restrictions are now in effect until at least Thursday morning. No new fires may be initiated and no additional material may be added to existing fires.
