    Weather Alerts
    Heat Advisory - 2:30am Wed Jul 15 2026

    ...HEAT ADVISORY REMAINS IN EFFECT FROM 11 AM THIS MORNING TO 9 PM EDT THIS EVENING...

    WHAT: Heat index values up to 101 expected.

    WHERE: In Connecticut, Southern Middlesex and Southern New London
    Counties. In New York, Northeast Suffolk, Southeast Suffolk, and
    Southwest Suffolk Counties.

    WHEN: From 11 AM this morning to 9 PM EDT this evening.

    IMPACTS: Hot temperatures and high humidity may cause heat
    illnesses.

    PRECAUTIONARY / PREPAREDNESS ACTIONS:

    A Heat Advisory is issued when the combination of heat and humidity
    is expected to make it feel like it is 95 to 99 degrees for two or
    more consecutive days, or 100 to 104 degrees for any length of time.

    Seniors and those with chronic health problems or mental health
    conditions are at an increased risk. Homes without air conditioning
    can be much hotter than outdoor temperatures.

    Use air conditioning to stay cool at home or go to a place that has
    air conditioning. If you don't have home air conditioning, continue
    to seek out cool spaces each day as long as it remains hot, and for
    a few days after if your home is still hot. Check on vulnerable
    friends, family members and neighbors.

    To reduce risk during outdoor work, the Occupational Safety and
    Health Administration recommends scheduling frequent rest breaks in
    shaded or air conditioned environments. Anyone overcome by heat
    should be moved to a cool and shaded location. Heat stroke is an
    emergency! In cases of heat stroke call 9 1 1.

    Air Quality Alert - 9:45am Wed Jul 15 2026

    ...AIR QUALITY ALERT IN EFFECT UNTIL MIDNIGHT EDT TONIGHT...

    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 tonight.

    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.
