The National Weather Service in Miami issued a heat advisory, which remains in effect through 7 p.m. A heat index combines temperature and humidity, leading to a higher “feels like” temperature.

Some counties — Miami-Dade, Broward, Palm Beach, Collier and Monroe — may see extreme heat, the National Weather Service said. People could experience long durations of high temperatures with little to no overnight relief from the swelter.

Those who work outdoors should stay hydrated and take breaks in the shade as often as possible, according to the National Weather Service. Check up on older adults and people who are sick, especially those without air conditioning.

“Heat can be very taxing on the body and can lead to heat related illnesses or make existing health conditions worse,” the National Weather Service said. “Everyone can be vulnerable to heat, but some more so than others.”

Infants and young children are particularly vulnerable to heat-related illness and death, and pregnant women are also at higher risk during extreme heat events.

Drivers are reminded that it “is NEVER safe to leave a child, disabled person or pet locked in a car, even in the winter,” the National Weather Service said. Children can die in hot cars in around 10 minutes, and 31 kids reportedly died in hot cars last year.
