Andrea Hayward-Maher, media liaison officer of the Australian Maritime Safety Authority (AMSA), said that bad weather continued to affect visibility in the search area to locate debris that might be linked to the missing jet, Xinhua reported.
The AMSA had on Thursday said that two objects, with the larger one about 24 metres long, had been spotted in the southern Indian Ocean on satellite imagery and that they might be related to the missing airliner.
The area where the objects were spotted is approximately 2,500 km southwest of Perth, the capital of Western Australia state.
Due to the bad weather condition, Australian aircraft have not till now found any object related to the missing plane.
"It is a large area and the weather is difficult (to search)," Hayward-Maher said.
According to the media, a Royal Australia Air Force(RAFF) P3 Orion plane was unable to locate the debris on Thursday, with Flight Lieutenant Chris Birrer telling reporters the weather conditions were so bad that "we were unable to see for very much of the flight".
Search planes from Australia, the US and New Zealand will continue the hunt on Friday, while merchant boats are also heading to the 23,000 square km search zone.

Haywayd-Maher told Xinhua that the AMSA tasked the Gulfstream jet "because of its endurance".
In addition, a Norwegian ship has arrived in the search zone on Friday night and another merchant ship is due to arrive on Friday night. But Hayward-Maher said she could not provide details of the second vessel, including its nationality.Due to the distance to and from the search area, the aircraft involved have a "loiter" time of approximately two hours.
Air Commodore John McGarry said at a press conference on Thursday that it would take four hours for the aircraft to arrive at the area from RAAF Base Pearce near Perth.
One merchant vessel is currently in the search area. A second merchant vessel is due to arrive Friday night.
According to a report from Beijing, more Chinese vessels will set out for the southern Indian Ocean to join the multinational search operation.
Chinese rescue vessels Haixun 01 and Nanhaijiu 101 will sail to the search area.
