"Temperatures early this week are topping out 10-15 degrees above normal from interior New England down through the mid-Atlantic," said AccuWeather Senior Meteorologist Heather Zehr. "A large high pressure area over the Southeast is pumping heat and humidity into the Northeast."

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.

The NWS said:

Heat is one of the leading weather-related killers in the United States, resulting in hundreds of fatalities each year. Heat can be very taxing on the body; check out the heat related illnesses that can occur with even a short period of exposure. Everyone can be vulnerable to heat, but some more so than others. According to The Impacts Of Climate Change On Human Health In The United States: A Scientific Assessment the following groups are particularly vulnerable to heat.
  • Young children and infants are particularly vulnerable to heat-related illness and death, as their bodies are less able to adapt to heat than are adults.
  • Older adults, particularly those with pre existing diseases, take certain medications, are living alone or with limited mobility who are exposed to extreme heat can experience multiple adverse effects.
  • People with chronic medical conditions are more likely to have a serious health problem during a heat wave than healthy people.
  • Pregnant women are also at higher risk. Extreme heat events have been associated with adverse birth outcomes such as low birth weight, preterm birth, and infant mortality, as well as congenital cataracts.

Check on vulnerable friends, family members and neighbors.

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

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.

In cases of heat stroke call 9 1 1.

Meanwhile, stay more comfortable while saving on energy costs by following these tips from Orange & Rockland Utilities:

  • Turn down or turn off air conditioning in your home while you are away or at work to help lower your energy bill. Set your air conditioner to the highest temperature your comfort and health will allow to help you save cooling money.
  • Close all doors and windows in your home while the air conditioning is running to keep things cooler at a lower price.
  • Cook, bake or perform other household activities that produce heat and humidity during the cooler times of the day and night.
  • Pull your curtains and shades closed to help block out the sun and the heat of the day.
