Indonesia hit by floods, landslides and strong winds across five provinces after heavy rainfall

Indonesia’s National Disaster Mitigation Agency (BNPB) has confirmed a surge in wet hydrometeorological disasters over the weekend, with flooding, strong winds and landslides affecting multiple regions across the country.

As of 21 December 2025, BNPB recorded disaster events in at least five provinces: South Kalimantan, Lampung, West Java, Central Java and East Java.

Flooding impacts South Kalimantan communities

In South Kalimantan, heavy rainfall on 19 December 2025, triggered flooding in five districts of North Hulu Sungai Regency.

Abdul Muhari, head of BNPB’s Disaster Data, Information and Communication Centre, said 563 houses and several public facilities were affected.

Floodwaters inundated residential areas, disrupting daily activities and forcing residents to limit movement.

By last Saturday, conditions were reported to be gradually improving as water levels began to recede.

Flooding was also reported in Banjar Regency, South Kalimantan, where rain affected 20 districts and submerged at least 384 houses.

The local Disaster Mitigation Agency (BPBD) established an emergency disaster post, distributed food and basic supplies, and coordinated with village authorities to monitor water levels and assess additional needs among affected households.

Central Java river overflow forces evacuations

In Central Java, intense rainfall caused the Bener River to overflow in East Purwokerto District, Banyumas Regency.

At least 24 houses were flooded, with water depths reaching up to 50 centimetres in some areas.

The Banyumas BPBD evacuated elderly residents as a precaution, delivered emergency assistance and carried out joint clean-up operations with local communities.

According to BNPB, floodwaters in the area receded by Saturday.

West Java experienced a combination of flooding, landslides and strong winds. In Parung District, Bogor Regency, heavy rain caused the Rengas River to overflow, inundating 28 houses on Friday.

On the same day, strong winds hit Dramaga District, damaging five houses — two severely, one moderately and two lightly. Local authorities, assisted by residents, conducted debris removal and temporary repairs to affected homes.

In Lampung Province, extreme weather struck Sribhawono District in East Lampung.

Homes damaged by extreme weather in Lampung and East Java

Strong winds and heavy rain damaged four houses severely and 17 lightly, while six animal pens were also reported damaged, affecting local livelihoods.

BPBD teams assessed structural damage and provided initial assistance to residents.

East Java was also hit by severe weather on Saturday.

 In Pasuruan Regency, rain accompanied by strong winds damaged houses across five districts. BNPB recorded 17 lightly damaged houses, two moderately damaged houses and one heavily damaged house.

In Singosari District, Malang Regency, strong winds damaged three houses moderately and 13 lightly.

Authorities warn of further risks as rain continues

Local disaster officials, together with residents, carried out communal clean-up efforts on Sunday to clear fallen trees and debris.

Separately, prolonged rainfall triggered landslides in six districts of Sukabumi Regency, West Java.

The Sukabumi BPBD reported one lightly damaged house, 11 other affected homes and damage to two public facilities.

Joint response teams have since cleared landslide material to restore access and reduce the risk of further incidents.

BNPB has urged regional governments and communities to remain vigilant, warning that continued rainfall could trigger additional flooding and landslides in the coming days, particularly in areas with saturated soil conditions and river systems already at high levels.
