Dangerous rip currents are being blamed for the death of 15-year-old swimmer in the waters off Sandy Hook on Sunday afternoon.

The National Park Service say the incident occurred around 4 p.m.

Six other people were rescued from the waters.

According to the National Park Service, two people were taken to Jersey Medical Center and two were sent to Monmouth Medical Center.

They said one denied medical attention.

There is a sign posted that warns beachgoers that it is an unprotected beach, meaning that there are no lifeguards. It also says that swimming is prohibited.

There is another a sign at the entrance to the beach that also warns beachgoers that it is unprotected and water conditions are subject to sandbars and severe drop-offs. The national park service tells News 12 Beaches C, D and G have lifeguards through Labor Day from 10 a.m. to 6 p.m.

It warns that swimming could put people in danger.

The National Park Service did not say exactly what happened as of Sunday night, but it did mention swimming happening at the beach.

Officials have warned those who will be going to the beach this Memorial Day weekend to just be mindful of those signs and put their safety first.

The rip tides are also resulted in 4 rescues in Seaside Heights on Saturday.
