The Fairfield County is now under a Heat Advisory, along with the entire New York City metro area and most of Connecticut, the weather service said.
The oppressive heat and humidity is expected to last through the weekend, with the Heat Advisory in effect util 8 a.m. Saturday.
An Excessive Heat Watch is in effect from Saturday morning through Sunday evening.
Heat index values for Thursday evening will be 100 to 103 — a combination of the temperature (in the low 90s) and humidity.
The heat index for Friday, Saturday and Sunday is 100 to 105 degrees.
The heat will be at the worst in the mid to late afternoon — with high temperatures in the low 90s. There is also a 50 percent chance of heavy rains, with thunderstorms possible.
The combination of high heat and humidity will increase the risk of health issues, especially for the elderly, those with chronic problems such as lung and heart disease, those working outside and other heat sensitive groups.
A Heat Advisory is issued when the combination of heat and humidity makes it feel like it is 100 to 104 degrees for two consecutive days.
An excessive heat watch means the combination of heat and humidity could create a dangerous situation, with heat-related illnesses possible.
The National Weather Service offered these tips:
- Take precautions if you work or spend time outside.
- Reschedule strenuous activities until early morning or evening.
- Wear lightweight and loose-fitting clothing.
- Know the signs and symptoms of heat exhaustion and heat stroke.
- Drink plenty of water
- Check on family members, neighbors and friends
- Schedule frequent breaks if working outdoors, and seek shade or air conditioning
- Anyone overcome by heat should be moved to a cool and/or shaded location.
- In an emergency, call 911.
Homes without air conditioning can be much hotter than outdoor temperatures — use air conditioning or go to a place with air conditioning to stay cool.
