JACKSONVILLE, Fla. -- Summer officially kicks off this Saturday and with it, temperatures will be close to triple digits.
With that in mind, safety advocates are warning parents about the dangers of leaving their children in hot vehicles.
This year, 13 children have already died after being left in blistering hot vehicles, according to Lesley Seaton with Wolfson Children's Hospital.
She said 52 percent of children left in cars were done so by accident.
"It's just an accident and was unintentional," she said.
The latest tragedy happened Wednesday in Georgia. Officials said a 22-month old boy died after his father accidentally left him in a hot car for at least seven hours while he was at work.
The father has now been charged with murder for the death of his son.
"It's very hard to wrap your head around the concept of someone leaving their child in the car, but a lot of times they fall asleep and they're really quiet," Seaton said.
Seaton said you should never leave your child in a hot vehicle no matter how brief your trip is. Temperatures can rise to dangerous levels in a matter of minutes. She tells parents to place subtle reminders in their vehicles so they don't accidentally leave their child behind.
"I always recommend for parents and caregivers to put their laptop or their purse in the backseat so they have to go to the back before they go into work," she said.
Authorities said if you see something, say something. You should call 911 immediately if you see a child alone in a hot vehicle, because you could wind up saving their life.
