"Entering the rainy season, the possibility of floods, landslides, and whirlwind increases," Sutopo Purwo Nugroho, the BNPB spokesman, noted in a statement, here, Thursday.
Precipitation will continue to increase, and the rainy season will peak in January, so the disaster threat is higher, according to Nugroho.
Floods have struck the districts of Tasikmalaya and Pangandaran in West Java Province, among other things.
In Tasikmalaya, 498 households in six villages located in three sub-districts were affected. The floods claimed five lives and rendered one person missing. Rescue personnel have been deployed to look for the missing victim.
A bridge, over Ciandum River in Cipatujah Village and connecting Tasikmalaya and Garut, collapsed, as the river overflowed its bank following incessant heavy rains.
In Pengandaran, 602 households in nine villages in six sub-districts were flooded. The disaster claimed the life of a villager and forced four families comprising 10 people to evacuate to higher ground.
