...EXTREME HEAT WARNING REMAINS IN EFFECT UNTIL 8 PM EDT TUESDAY...
* WHAT...Dangerously hot conditions with heat index values up to 110
expected.
* WHERE...Portions of southern Connecticut, northeast New Jersey,
and southeast New York.
* WHEN...Until 8 PM EDT Tuesday.
* 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...The highest heat index values will take place
each day during the afternoon.
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.
