    Air Quality Alert - 3:28pm Fri Jul 17 2026

    ...AIR QUALITY ALERT IN EFFECT UNTIL MIDNIGHT EDT SATURDAY NIGHT...

    The New York State Department of Environmental Conservation has
    issued an Air Quality Health Advisory for the following counties:

    New York, Bronx, Kings, Queens, Richmond, Nassau, Suffolk,
    Westchester, Rockland, Orange, Putnam.

    until midnight EDT Saturday night.

    Air quality levels in outdoor air are predicted to be greater than
    an Air Quality Index value of 100 for the pollutant of Fine
    Particulates. The Air Quality Index, or AQI, was created as an easy
    way to correlate levels of different pollutants to one scale. The
    higher the AQI value, the greater the health concern.

    When pollution levels are elevated, the New York State Department of
    Health recommends that individuals consider limiting strenuous
    outdoor physical activity to reduce the risk of adverse health
    effects. People who may be especially sensitive to the effects of
    elevated levels of pollutants include the very young, and those with
    preexisting respiratory problems such as asthma or heart disease.
    Those with symptoms should consider consulting their personal
    physician.

    For additional information, please visit the New York State
    Department of Environmental Conservation website at,
    https://on.ny.gov/nyaqi, or call the Air Quality Hotline at
    1 800 5 3 5, 1 3 4 5.
