Extremely "dangerous" weather is forecast for the Hudson Valley and many parts of New York State.

New York State Department of Environmental Conservation Commissioner Basil Seggos and State Department of Health Commissioner Dr. Mary T. Bassett issued an Air Quality Health Advisory for the New York City region and Hudson Valley for Thursday, August 4, 2022.

Air Quality Health Advisory Issued for New York City and Hudson Valley


"DEC and DOH issue Air Quality Health Advisories when DEC meteorologists predict levels of pollution, either ozone or fine particulate matter are expected to exceed an Air Quality Index (AQI) value of 100. The AQI was created as an easy way to correlate levels of different pollutants to one scale, with a higher AQI value indicating a greater health concern," the DEC stated. "People, especially young children, those who exercise outdoors, those involved in vigorous outdoor work and those who have respiratory disease (such as asthma) should consider limiting strenuous outdoor physical activity when ozone levels are the highest."

The advisory is in effect from 11 a.m. through 11 p.m on Thursday. The pollutant of concern is ozone, according to the DEC.

"Summer heat can lead to the formation of ground-level ozone, a major component of photochemical smog. Automobile exhaust and out-of-state emission sources are the primary sources of ground-level ozone and are the most serious air pollution problems in the northeast. This surface pollutant should not be confused with the protective layer of ozone in the upper atmosphere," the DEC adds.
