A heat advisory will be in effect in Norwich and several other Connecticut communities through 8 p.m. on Wednesday, July 30.
The National Weather Service is predicting "high heat and humidity" through most of Southern New England, except the Berkshires and the Cape and Islands.
High temperatures are expected to be in the 90s, with heat indices between 95 and 100 degrees Fahrenheit.
The heat advisory was launched the morning of Monday, July 28.

Safety tips for the heat advisory
The hot temperatures and high humidity can cause heat illnesses, such as heat exhaustion and heat stroke, according to the National Weather Service.
People are advised to stay in air-conditioned locations as much as they can, drink fluids even when they do not feel thirsty, and take cool showers or baths to cool down, according to the CDC.
You should schedule outdoor activities carefully and wear loose, lightweight, light-colored clothing and sunscreen, the CDC said.
The CDC also said it is important to check on friends and neighbors, especially older adults, young children, and people with chronic medical conditions.
People on certain medications, such as antidepressants, might feel especially hot as well.
Symptoms of heat exhaustion include heavy sweating, faintness, dizziness, fatigue, low blood pressure upon standing, muscle cramps, nausea, headache, and a weak, rapid pulse, according to the Mayo Clinic.
If you think you have heat exhaustion, you should stop all activity and rest, move to a cooler place, and drink cool water or sports drinks, the Mayo Clinic said.
The clinic recommends contacting your doctor if symptoms get worse or do not improve within an hour.
Seek immediate medical attention for a person with heat exhaustion if they become confused or distressed, lose consciousness, or are unable to drink, the Mayo Clinic said.
