MELBOURNE, Australia (AP) — An Australian warship on Monday rescued a Lithuanian solo rower who had encountered a tropical cyclone while attempting to cross the Pacific Ocean from California.

Aurimas Mockus was taken aboard Royal Australian Navy landing ship HMAS Choules, where he was undergoing a medical assessment, Vice Adm. Justin Jones said in a statement.

“Because of highly unfavorable sea conditions, Mr. Mockus’s boat could not be recovered except for two oars and some personal items,” the Australian Maritime Safety Authority, which coordinated the rescue, said in a statement.

The 44-year-old adventurer had been stranded for three days in the Coral Sea around 460 miles east of the Queensland state coastal city of Mackay. He had rowed there in an enclosed boat nonstop from San Diego headed for the Queensland capital, Brisbane.

He began the 7,500-mile journey in October and was days away from Brisbane when he ran into the storm, which is forecast to cross the Australian coast within days.

Brisbane is 500 miles south of Mackay by air.

Mockus activated an emergency beacon on Friday after rowing into stormy seas and 50 mph winds generated by Tropical Cyclone Alfred, the rescue authority said.

The authority sent a plane that made radio contact with Mockus on Saturday. Mockus reported he was “fatigued,” the authority said.

The warship is taking Mockus south beyond Brisbane to Sydney in New South Wales, the navy said.

The cyclone has continued to track south and on Monday was 280 miles east of Brisbane, authorities said.

The cyclone is forecast to turn west and cross the Australian coast on Thursday or Friday.

Solo rowers have crossed the Pacific Ocean nonstop in the past

Mockus was attempting to become one of the few rowers who have crossed the Pacific alone and without stopping.
