A search of the Great South Bay for a man who State Police said jumped from the northbound main span of the Robert Moses Causeway Bridge was suspended midmorning Tuesday because of weather conditions.
Police said the incident was reported in a 911 call from a motorist about 4:30 a.m. and that marine and aviation units from the Nassau and Suffolk county police departments had been involved in the search.
The U.S. Coast Guard and a marine unit from the Bay Shore Fire Department also had searched bay areas.
But State Police said in a statement at 9:57 a.m. that the search has been suspended.
Officials said prolonged survivability was unlikely because of water conditions. The National Weather Service had issued a small-craft advisory Tuesday for South Shore bays and the Atlantic Ocean.
Police said that after the 911 call, which reported "a suspicious vehicle" stopped on the main span, arriving troopers found the car in the right lane of the northbound span and located "a male subject hanging from the bridge beam." Police said a trooper "engaged the subject in a brief conversation," but that the man then "let go" -- and fell from the span into Great South Bay.
Police said the case is being considered a possible suicide.
