The death toll has climbed to at least 91 dead and 68 missing in Indonesia, after flash floods that struck following torrential rains, officials said Thursday, according to CNN.

At least 91 people have been injured, and more than 900 people have been displaced.

The hardest-hit area is the remote location of Teluk Wondama, about eight to 10 hours by ship from Manokari, West Papau, officials said. Communication lines also have been disrupted. About 80 percent of the town of Wasior, in the Teluk Wondama district, has been damaged.

Help and supplies -- such as tents, blankets, clothes and food -- have arrived in the region, said Priyadi Kardono, a spokesman for the National Disaster Mitigation Agency.

It`s monsoon season in Indonesia, and flooding is not unusual. However, the Bureau of Meteorology, Climatology and Geophysics is forecasting unusually heavy rains this year.
