Air Quality Alert
Issued: 6:38 PM Jun. 11, 2026 – National Weather Service
...AIR QUALITY ALERT IN EFFECT UNTIL 11 PM EDT THIS EVENING...

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

Nassau and Suffolk.

until 11 PM EDT this evening.

Air quality levels in outdoor air are predicted to be greater than
an Air Quality Index value of 100 for the pollutant of Ground Level
Ozone. 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.

Heat Advisory
Issued: 5:34 PM Jun. 11, 2026 – National Weather Service
...HEAT ADVISORY REMAINS IN EFFECT UNTIL 8 PM EDT FRIDAY...

* WHAT...Heat index values around 100 expected.

* WHERE...In Connecticut, Northern Fairfield, Northern Middlesex,
Northern New Haven, Southern Fairfield, and Southern New Haven
Counties. In New York, Northern Nassau, Northwest Suffolk,
Southern Nassau, and Southwest Suffolk Counties.

* WHEN...Until 8 PM EDT Friday.

* 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.
