Are Hilton Head Island beaches safe to swim after Tropical Storm Debby? What to know

Now that the brunt of Tropical Storm Debby has passed, Hilton Head’s beach patrol said it’s safe to swim at the island’s beaches. However, swimmers should take notice that a rip current advisory is in place until 8 p.m. Thursday.

Rip currents are forceful currents of water flowing away from shore at surf beaches and usually extend from near the shoreline, through the surf zone and past the line of breaking waves, the National Oceanic and Atmospheric Administration said .

When under certain conditions, the currents reach dangerous speeds and pose a threat to swimmers if they’re pulled offshore and unable to keep themselves afloat. Rip currents can pull underwater even the strongest swimmers.

Those who make it out to Hilton Head’s beaches Thursday will see yellow flags , which indicates “medium” hazards at the beach.

Shore Beach Service Operations Manager Mike Wagner said lifeguards with the service will be posted at their normal stations and keep their typical hours. Wagner warned beachgoers to watch for the beach patrol’s flags, especially purple for stinging marine life. He said jellyfish have been especially prevalent.

Rip currents usually form at low spots or breaks in sandbars, NOAA said. They’re also found near structures like groins, jetties and piers.

If you’re caught in a rip current, relax and do not try and swim against it. Swimmers should work to swim parallel to the beach, perpendicular to the current in either direction. If a person can’t escape, float or tread water and wave for help.
