A day after beachgoers reported seeing a swimmer go under water before he went missing off the Huntington Beach coast, search-and-rescue crews suspended a formal search and said they would "on the lookout" Saturday.

The incident started when a person saw the swimmer "twirling" near the shoreline. Unsure if he needed help, the witness reported the sighting to officials around 9:30 p.m. Friday, Huntington Beach Police Department Lt. Kent Ferrin said.

The reporting party lost sight of the person between towers four and six, and never saw him get out of the water.

Crews searched overnight for the man, said to be wearing a tank top and shorts, and suspended the search by 3 a.m., Sgt. Mendez said.

Although police initially said search efforts would resume Saturday, and include a police helicopter, they later said it would only be treated as a case of "be on the lookout."

Early Saturday morning, officials located a surfer who had suffered a heart attack while in the water and went into cardiac arrest.

Police initially said the man died, but later said he was resuscitated and did not know his condition.

The surfer was not believed to be the missing person, according to police.

Both instances happened as a beach hazard statement was issued for L.A. and Ventura counties.

The statement warned of increased risk for drowning in the ocean on Saturday because rip currents could pull surfers and swimmers out to sea and sneaker waves could wash people off beaches and rock jetties, according to the National Weather Service.

Waves between 3 to 5 feet, with the highest surf being at south to southeast-facing beaches, was expected.
