KIAWAH ISLAND — Thunderclouds loomed on the horizon at the Ocean Course all day Monday, and forecasters say there’s a good chance of thunderstorms through the week.

On the exposed dunes of the Atlantic Ocean, the protocol is simple if lightning is around: Leave.

“You have to seek the nearest point of shelter” if weather warnings go up around the course, said Brett Sterba, PGA of America championship director.

Where is that point? “Your car.”

Now, that can be a little problematic when your car is parked at a remote lot on the far end of Kiawah Island.

The protocol calls for passengers to load en masse onto the shuttle buses to be routed back to the shuttle parking areas. Tickets will be honored if weather passes and play resumes.

There are one or two tent-sheltered areas open to the general public on the course, such as the golf shop. But a tent with a metal frame — even a big one — isn’t safe shelter, Sterba warned.
