...EXTREME HEAT WARNING NOW IN EFFECT FROM NOON WEDNESDAY TO 9 PM
EDT FRIDAY...
...EXTREME HEAT WATCH NOW IN EFFECT FROM FRIDAY EVENING THROUGH
SATURDAY EVENING...
* WHAT...For the Extreme Heat Warning, dangerously hot conditions
with heat index values up to 111 expected. For the Extreme Heat
Watch, dangerously hot conditions with heat index values up to 101
possible.
* WHERE...Portions of southern Connecticut, northeast New Jersey,
and southeast New York.
* WHEN...For the Extreme Heat Warning, from noon Wednesday to 9 PM
EDT Friday. For the Extreme Heat Watch, from Friday evening
through Saturday evening.
* 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 has potential to be 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.
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. Wear light weight and loose fitting clothing when
possible, and drink plenty of water.

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. Wear light weight and loose fitting clothing when
possible, and drink plenty of water.

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.
from 11 AM to 11 PM EDT Wednesday.
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.

Department of Environmental Conservation website at,
