REGIONAL SUMMARY:
During the eleventh week of 2026, a total of 13 disaster events were reported across the ASEAN region, including floods, landslides, storms, and wind-related disasters in Indonesia, Malaysia, and Thailand. In Indonesia, Badan Nasional Penanggulangan Bencana (BNPB) reported incidents across South Sumatra, West Java, Central Java, and West Nusa Tenggara. In Malaysia, Agensi Pengurusan Bencana Negara (NADMA) reported flooding and landslides in Sabah and Sarawak. In Thailand, the Department of Disaster Prevention and Mitigation (DDPM) reported storms and strong winds in Lampang, Chiang Mai, Mae Hong Son, Tak, Nan, Sukhothai, Phetchabun, and Lamphun.
HIGHLIGHT:
In Thailand, storms accompanied by strong winds affected several provinces in the Northern Region. According to the DDPM, the storms damaged a total of 519 houses across multiple districts. Local authorities, including provincial disaster prevention and mitigation offices and district administrations, conducted rapid damage assessments and coordinated assistance for affected households. Emergency teams and local officials also supported debris clearing and relief distribution while monitoring weather conditions.
HYDRO-METEO-CLIMATOLOGICAL:
For the past week, data from the ASEAN Specialised Meteorological Centre (ASMC) indicated medium to high 7-day average rainfall across Brunei Darussalam, Indonesia, Malaysia (Sabah and Sarawak), Myanmar (northern and eastern areas), the Philippines (Visayas and Mindanao, and Timor-Leste. The high rainfall accumulation east of southern Philippines reflected the development of Tropical Cyclone NURI. As of this reporting, no active tropical disturbance is being monitored within the ASEAN Region (JTWC).
GEOPHYSICAL:
Three (3) significant earthquakes (M>5.0) were recorded by Indonesia’s Badan Meteorologi, Klimatologi, dan Geofisika (BMKG). Mount Semeru (alert level III), Anak Krakatau (alert level II), Lewotobi Laki-laki (alert level II), Ili Lewotolok (alert level II), and Ibu (alert level II) in Indonesia, and Taal (alert level 1), Mayon (alert level 3), and Kanlaon (alert level 2) volcanoes in the Philippines reported recent volcanic activity according to Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) and the Philippines Institute of Volcanology and Seismology (PHIVOLCS).
OUTLOOK:
According to the ASEAN Specialised Meteorological Centre (ASMC), for the coming week, indicates drier than usual conditions over southeastern Mainland Southeast Asia, the northeastern Maritime Continent, and parts of the western–central equatorial region, alongside cooler than average temperatures across much of Mainland Southeast Asia and the northeastern Maritime Continent. A slight increase in the likelihood of very heavy rainfall is forecast over Timor and Timor-Leste, while the risk of extreme heat remains low across the region. La Niña conditions are continuing to weaken and are expected to transition to ENSO-neutral by March 2026, while the Indian Ocean Dipole (IOD) has remained in a positive phase since February 2026.
