The discoveries have been made during a search for victims of a possible serial killer.
Newsday says divers will concentrate on Hemlock Cove on Wednesday.
Suffolk County Police Commissioner Richard Dormer is planning an afternoon media briefing on the investigation.
On Tuesday, police in neighboring Nassau County confirmed that two sets of remains found this week were human.
The findings come after police in Suffolk uncovered eight sets of human remains since December along the same highway.
Authorities haven't linked all the remains found in the past five months to the same suspect. However, they theorize that the first four bodies could be victims of a serial killer.
