An air quality health advisory has been issued for the Hudson Valley region for the second consecutive day, due to high ozone levels and smoke from Canadian wildfires. The advisory is in effect from 11 a.m. to 11 p.m. for Rockland, Westchester, Dutchess, Putnam, Sullivan, and Ulster counties. The New York State Department of Environmental Conservation (DEC) and the State Department of Health (DOH) issued the advisory as ozone levels are expected to exceed an Air Quality Index (AQI) value of 100, indicating potential health risks.
According to the New York State DEC, ground-level ozone forms when sunlight reacts with emissions from vehicles and industrial sources. This can lead to photochemical smog, which is particularly concerning for individuals with respiratory conditions, young children, and the elderly. The DEC advises these groups to limit outdoor activities during peak ozone hours, typically from afternoon to early evening.
The ongoing wildfires in Canada are contributing to the elevated pollution levels, affecting much of the northern United States. As of early Wednesday (June 4), the AQI in the Lower Hudson Valley was measured as "Moderate," with an AQI score of 54 and an ozone level of 101, making the air unhealthy for sensitive groups.
Residents are encouraged to minimize automobile travel and use public transportation to help reduce emissions. For the latest air quality levels, visit airnow.gov.
