Central Oklahoma’s first heat alert of the summer was issued at noon Tuesday. The Emergency Medical Services Authority responded to five heat-related illnesses between 9 a.m. and noon, and at 4:30 p.m. responded to a sixth. Two people were taken to Integris Southwest Medical Center, one to the Veterans Affairs Medical Center and another to St. Anthony Hospital, while two others were treated on the scene. "This shows that the morning isn’t cooling enough for folks like they think it is,” said Lara O’Leary, EMSA spokeswoman. "Being out in the heat takes a toll on public safety. People need to taper off their activities, stay indoors and make sure to check on their elderly loved ones. It’s worth the drive to walk into their home and make sure it’s cool enough.” A heat alert is issued when five or more heat-related medical calls are made to EMSA in a 24-hour period and dangerously hot weather is expected to continue. By 3 p.m., EMSA reported five patients with heat-related illnesses in Tulsa — three of those children. Kids cannot regulate body temperatures or perspire as much as adults, which aids in cooling down, EMSA reported. So kids need extra attention and care. The Oklahoma Mesonet site at Fairview reached 105 degrees Tuesday afternoon, the highest temperature reading this year at a Mesonet site.
