Heat advisory issued for South Florida — and it could feel 105 to 111 degrees

Forecasters have issued a heat advisory for Friday in Miami-Dade, Broward and Palm Beach counties, with temperatures expected to feel like 105 to 111 degrees.

The advisory is in effect from 11 a.m. to 6 p.m. Forecasters have not issued any advisories for the weekend.

While actual air temperatures will stay in the 90s on Friday, the mix of humidity and temperature, known as the heat index, will make it seem hotter — and more dangerous.

“When you step outside, it feels like a steam room,” Said Lissette Gonzalez, CBS News Miami meteorologist.

Friday’s advisory covers southeast, southern and southwest Florida, with the strongest heat expected along the Gulf Coast, driven by an easterly wind flow. Some parts of the Upper Keys are included in the advisory.

The National Weather Service in Miami issues a heat advisory if the heat index is 105 degrees for at least a couple of hours. Before 2023, the weather service issued a heat advisory when the heat index hit 108 degrees.

Officials warn that the combination of extreme heat and humidity could lead to heat-related illnesses, especially for those working or spending extended time outdoors.

Weekend forecast

Will there be heat advisories this weekend?

It is still too early for a definitive answer, said National Weather Service meteorologist Robert Garcia. He said advisories are issued on a day-to-day basis.

But advisory or not, South Florida will still be in for a hot weekend, and Garcia recommended precautions.

According to the current weather service forecast, Saturday will bring more sun, with a high near 90 and a heat index as high as 102.

Sunday will bring a 20% chance of rain after 2 p.m., with a high around 90.

Taking precautions in the South Florida heat

People are urged to take precautions, including:

▪ Staying hydrated by drinking plenty of water

▪ Avoiding direct sunlight

▪ Taking frequent breaks in shaded or air-conditioned areas

Checking on vulnerable individuals, such as the elderly and young children

The Occupational Safety and Health Administration advises outdoor workers to schedule frequent rest periods and to be alert for signs of heat exhaustion or heat stroke. In the event of a heat emergency, call 911.
