Severity: Unknown Urgency: Unknown

The New York State Department of Environmental Conservation has issued an Air Quality Health Advisory for the following counties: Nassau and Suffolk. from 11 AM to 11 PM EDT Thursday. 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.

Northern Fairfield; Northern New Haven; Northern Middlesex; Southern Fairfield; Southern New Haven; Northwest Suffolk; Southwest Suffolk; Northern Nassau; Southern Nassau Jun 11, 02:49 AM - Jun 11, 04:00 PM
Severity: Moderate Urgency: Expected

In New York, Northern Nassau, Northwest Suffolk, Southern Nassau, and Southwest Suffolk Counties. * WHEN...From noon today to 8 PM EDT Friday. * IMPACTS...Hot temperatures and high humidity may cause heat illnesses.

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.
