Several cities and towns opened cooling centers that they said would be open for the rest of the week.
WFSB’s meteorologists predicted a second straight day of temperatures in the 90s.
While it wasn’t bad outside on Wednesday morning, it was predicted to be a potential record-setting day.
Doctors said this kind of weather can pose health risks.
They continue to remind people to “look before you lock” to make sure children or pets aren’t left inside a hot vehicle.
Emergency physician Dr. Kenneth Robinson of Hartford Hospital said those most at risk are the young and the old.
Robinson said people who suffer from any heart or lung issues are also at a greater risk.
"That can make breathing more difficult for people with underlying respiratory illness,” he explained.
Robinson also said that it only takes a few minutes of intense sun to bring on heat exhaustion and possibly heat stroke.
He said some symptoms to be aware of are dizziness and headaches.
"If the body temperature goes up high over 103, 104, they may have a change in behavior, a change in mental status, or they may become unconscious,” Robinson said.
Robinson recommended keeping an eye on the most vulnerable.
