New York City is under an air quality health advisory for ozone, effective from 11 a.m. to 11 p.m. in the Metro area. The advisory is activated when pollution levels are forecasted to exceed an air quality index value of 100, with ozone being the primary concern. Ground-level ozone is formed when sunlight reacts with nitrogen oxides and volatile organic compounds from vehicle emissions and out-of-state pollution. Forecasts indicate that the presence of wildfire smoke may enhance ozone production, prompting warnings for sensitive populations to limit outdoor activities.
