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. An Extreme Heat Watch means that the combination of heat and humidity could create a dangerous situation in which heat illnesses are possible. 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.

Air Quality Alert

Air Quality Alert issued July 2 at 3:05AM EDT by NWS Upton NY
Jul 2, 3:05 AM Jul 2, 11:00 PM
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.

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.
