At least 49 families were hit in Flores, in the east of Indonesia’s extensive archipelago, Raditya Jati, a BNPB spokesman said in a statement.
“Dozens of houses were buried in the mud in the village of Lamanele … houses of residents washed away by the flood,” said Raditya, referring to the eastern part of Flores.
On the island of Adonara, east of Flores, a bridge collapsed and rescue workers were battling heavy rain, strong wind and waves, he added.
“Heavy rains and overflowing water drowned people’s homes and also claimed the lives of several victims,” East Timor’s deputy prime minister, José Reis, said in a statement.
“There are roads that collapsed, trees fell and made access to some areas difficult,” he said, calling the incident the worst in Timor-Leste in 40 years.
Power supplies have been cut and the presidential palace flooded due to heavy rains and strong winds that have battered Dili since Saturday night.
Civil protection officials in Timor-Leste could not be reached immediately for comment. Posts on social media showed collapsed buildings and vehicles submerged by floods.
Indonesia’s meteorological agency said a tropical cyclone was approaching the Savu Strait between the southern part of Nusa Tenggara province and the north coast of East Timor, warning that it could bring even more rain, waves and winds.
