    Heat Advisory - 2:30am Wed Jul 15 2026

    ...HEAT ADVISORY REMAINS IN EFFECT UNTIL 9 PM EDT THIS EVENING...

    WHAT: Heat index values up to 101.

    WHERE: Portions of southern Connecticut, northeast New Jersey,
    and southeast New York.

    WHEN: Until 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.
