Temperatures were to be in the upper 80s over the weekend but return to the 90s by early next week.

MIAMI — Good news: the unbelievably hot and humid weather conditions have broken.

But don’t celebrate too much because the 90-degree-plus heat will be back.

Craig Sullivan with the National Weather Service office in Tulsa said temperatures should be more seasonal for at least the next week or so because after all, it’s July.

“It’s not been anything super unusual,” Sullivan said. “Most years you will have a spell like that.”

While temperatures had been in the mid to upper 90s for most of the last 10 days, a low-pressure system rolled into the area, bringing a little rain and cooler conditions.

Temperatures were to be in the upper 80s over the weekend but return to the 90s by early next week.

Integris Miami Hospital has not noticed an increase in cases, according to Integris spokesperson Kristi Wallace.

The City of Miami Solid Waste Department has been running routes earlier since Memorial Day, starting shifts at 6 a.m. through Labor Day.

“They drink more water,” said Miami solid waste manager Kevin Horn. They have water available for them to drink more. Drink before you need it and drink after you need it.”

Horn said employees are told to take breaks when needed.

“We tell them to take a break and get in where it's cool; when it gets really hot, take a break in the shade somewhere or hop up in the cab with the air conditioner on.”

There are two forms of heat-related illness: heat exhaustion and heat stroke, which is the most serious of the two.

Heat stroke occurs when the body temperature rises above 104 degrees.

Signs and symptoms are dizziness and fainting, extreme fatigue, nausea, vomiting, rapid heartbeat, mental confusion, seizures, lack of sweating and severe headache.

“You really only have 20 to 30 minutes to cool those people off, or they can have serious lifetime, or even fatal, consequences,” Dr. Mark Osborn said.

There are two types of heat exhaustion: water depletion — excessive thirst, weakness, headache and loss of consciousness — or salt depletion — nausea and vomiting, muscle cramps and dizziness.

Osborn hasn’t seen an increase in heat related issues, “but it’s coming.”

High school football practices begin Aug. 7. The same day, high school and middle schools begin playing softball.

“The No. 1 sport for heat stroke in the United States is football,” Osborn said. “When I was growing up, kids worked outside or hauled hay. Now they are not as acclimatized to getting out in the heat.

“The coaches are better. When I was in football in 1973, that was when they just started letting people drink water. They are better that way. The key thing is for coaches to be able to recognize who is in trouble.”
