Wednesday’s highs will hit the lower 90s with feels like temps in the triple digits – 105 to 110 degrees. A Heat Advisory was issued for Miami-Dade, Broward, Palm Beach, and Monroe counties until 6 p.m.

It wasn’t enough to keep Brian Stellberg and his friend David Giraldo off their bicycles, however.

“Just try to hydrate a lot,” said Stellberg. “My only option is to ride during the middle of the day, just kind of get used to it and let your body acclimate to the heat.”

Harry Levine and his dog, Dr. Watson, have a cool routine for the climbing temperature, hosing down at the dog park.

“The heat can kill dogs,” said Levine. “We have to be very careful.”

A Heat Advisory means that a period of hot temperatures is expected. The combination of hot temperatures and high humidity will combine to create a situation in which heat illnesses (heat exhaustion and dehydration) are possible. Drink plenty of fluids, stay in air-conditioned rooms, and stay out of the sun.

On Tuesday, Roberto Diaz began feeling lightheaded and nauseous while operating a chipper machine for All American Tree Service. He said the heat forced him to stop working and go home.

“My body started to shake, I was trembling,” he said. “When you start to feel that way, you have to stop. Being alive is more important that doing a job.”
