The sound of a lifeguards whistle is something most kids dread. It normally means they're doing something wrong, or that it's adult swim time.
But tomorrow, that sound might ring through pools because of something worse...lightning.
The next two days could bring severe weather storms and Lubbock Aquatics Supervisor, Katie Yandell says that's something to be concerned about.
"It's a dangerous environment," Yandell said."We are the highest thing at this point and so you want to make sure you're taking every precaution."
Their precautions include some rules that all pool-goers should follow:
1.) Always listen to the lifeguard or parent supervision. They are looking out for your safety and know when the water is unsafe.
2.) Always wait at least 30 minutes before getting back in the water after seeing lightning or hearing thunder.
3.) Seek shelter immediately if lightning is seen.
"Just be aware of your surroundings," Yandell said. "Then the weather that's about to occur and respect the lifeguards and their decisions to get you out of the water because they are doing it for your safety."
