HIGHLIGHT:
In Week 24, heavy rainfall events caused significant disasters in several areas in the region. In the Northern Region of Viet Nam, the VDDMA reported widespread flooding and landslides in several provinces. The floods swept away 2 persons and another 1 died from a landslide. The widespread flooding inundated and damaged 2.4K houses, 2.4 ha of rice and crops, 157 ha of aquaculture areas. In addition, 513 cattle heads and 230 poultry were also reportedly swept away. According to the VDDMA, the heavy rainfall also induced landslides in several areas, with a total volume of over 21.4K cubic metres of soil, rocks, and concrete. The combined impacts of these flooding and landslides affected about 9.6K persons in Northern Viet Nam. In Thailand, the DDPM also reported widespread flooding that affected about 1.8K persons in Chanthaburi. Meanwhile, in Indonesia, high average rainfall in Sumatra, Sulawesi, and Papua resulted to flooding and landslide disasters that affected a total of 12.4K individuals as reported by the BNPB. Authorities conducted emergency response and provided immediate assistance to affected communities.
HYDRO-METEO-CLIMATOLOGICAL:
For the past week, data from the ASEAN Specialised Meteorological Centre (ASMC) indicates a 7-day average rainfall ranging from medium to high across Brunei Darussalam, Cambodia, Indonesia (Sumatra, Kalimantan, Sulawesi, Maluku, and Papua), northern Lao PDR, Malaysia (Peninsular, Sabah, and Sarawak), Myanmar, the Philippines, Thailand (Northern, Northeastern, and parts of Central) and Viet Nam (Northern, Southern, and parts of Central). Currently, there is no active tropical disturbance being monitored in the ASEAN region (JTWC).
GEOPHYSICAL:
Six (6) significant earthquakes (M>5.0) were recorded by Indonesia’s BMKG Malaysia’s Jabatan Meteorologi Malaysia (JMM), and the Philippine Institute of Volcanology and Seismology (PHIVOLCS). Mount Ibu (alert level IV), Mount Semeru (alert level III), Mount Marapi (alert level III), Mount Lewotobi Laki-Laki (alert level III) in Indonesia, and Kanlaon (alert level 2), Mayon Volcano (alert level 1), Taal (alert level 1), and Bulusan (alert level 1) in the Philippines reported recent volcanic activity according to Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) and PHIVOLCS.
OUTLOOK:
According to the ASEAN Specialised Meteorological Centre (ASMC), warmer than usual temperature is predicted over most of the Maritime Continent. Warmer than usual temperature is also predicted over the southern half of Mainland Southeast Asia. There is a moderate increase in chance for extreme hot conditions to persist over southern Thailand and northern Peninsular Malaysia. There is also a small increase in chance for extreme hot conditions over parts of central and southern Mainland Southeast Asia, Sumatra, and the eastern Maritime Continent. The El Niño has transitioned to ENSO neutral conditions.
