    Extreme Heat Warning - 11:11am Fri Jul 3 2026

    ...EXTREME HEAT WARNING REMAINS IN EFFECT UNTIL 9 PM EDT SATURDAY...

    WHAT: Dangerously hot conditions with heat index values 105 to
    110.

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

    WHEN: Until 9 PM EDT Saturday.

    IMPACTS: Extreme heat and humidity will significantly increase
    the potential for heat related illnesses, particularly for those
    working or participating in outdoor activities.

    ADDITIONAL DETAILS: This is a multi-day extreme heat event with
    near record high temperatures and little overnight relief. This
    level of heat can be deadly for those without adequate cooling and
    hydration. Impacts to transportation infrastructure and electrical
    and water systems are also possible.

    PRECAUTIONARY / PREPAREDNESS ACTIONS:

    An Extreme Heat Warning means that the combination of heat and
    humidity is expected to make it feel like it is 105 degrees or
    greater. Take extra precautions if you work or spend time outside.
    When possible, reschedule strenuous activities to early morning or
    evening. Know the signs and symptoms of heat exhaustion and heat
    stroke. Wear light weight and loose fitting clothing when possible,
    and drink plenty of water.

    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.
