Heat advisory issued for Miami-Dade and Broward — and it could feel like 105
A heat advisory has been issued for Miami-Dade and Broward counties for Monday and will be in effect noon to 6 p.m.
South Florida also was under a heat advisory on Friday. Although the weekend was scorching hot in the region, the National Weather Service in Miami didn’t issue heat advisories for Saturday and Sunday.
Actual air temperatures will continue to hit the low-90s on Monday. But mixed with humidity, what’s known as the heat index could make it feel like 105 for several hours. That’s what triggered the advisory.
“It is a warm and sticky start,” said Lissette Gonzalez, CBS News Miami meteorologist. “Hydrate, hydrate, hydrate.”

Experts say that the heat and humidity combo could lead to heat-related illnesses, especially for those working or spending extended time outdoors.
Will South Florida see more advisories for the rest of the week?
It’ll still be hot, with highs around 90. But rain in the forecast will keep it a little cooler than last weekend and Monday, at least under the threshold that triggers a heat advisory.
Monday’s 20% rain chance will rise to 30% Tuesday, 60% Tuesday night and 50% Wednesday, according to the weather service.
Rain “will bring relief from the heat,” Gonzalez said.
But on Friday and through next weekend, the rain chance goes down again.
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.
