Indonesian authorities are examining photos of debris that could be from missing AirAsia Flight QZ8501, a government official said Tuesday.

The debris spotted by a search team is located off the coast of Indonesia's central Kalimantan province, Djoko Murjatmodjo, an aviation official at the Transport Ministry, told reporters.

Debris photos show at least one triangular metallic object floating in the water, the official said.

Ships, planes and helicopters have been searching for Flight QZ8501 since it went missing Sunday on its way from the Indonesian city of Surabaya to Singapore.

Officials are concerned about currents in the area. If bad weather persists, currents could spread the possible debris before crews get to it.

The Airbus A320-200 with 162 people on board lost contact with air traffic control early Sunday shortly after the pilot requested permission to turn and climb to a higher altitude because of bad weather, according to Indonesian officials.
