DDM offices in the affected area are providing the necessary assistance of food items and Non-Food Items (NFIs) by coordinating with the respective state/region Disaster Management Bodies. An estimated 196.75K USD worth of assistance has been provided to the affected community from Myanmar Authorities.

The AHA Centre remains committed to liaising with NDRRMC-OCD for the dispatch of the requested DELSA relief items and stands ready to provide further support as needed.
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 Cambodia, Indonesia (Northern Sumatra, Kalimantan, Sulawesi, Maluku, and Papua), Lao PDR, Malaysia, Myanmar, Southern Thailand, and Viet Nam. As of reporting, Tropical Disturbance INVEST 91W was estimated based on all available data at 1,075 km east-northeast of Extreme Northern Luzon. Invest 91W is tracking towards the west southwest and will continue to do so over the next few days, but no significant development is expected at this time (JTWC).
GEOPHYSICAL:
Six (6) significant earthquakes (M>5.0) were recorded by Indonesia’s Badan Meteorologi, Klimatologi, dan Geofisika (BMKG) and the Philippine Institute of Volcanology and Seismology (PHIVOLCS). Mount Semeru (alert level II), Lewotobi Laki-laki (alert level III), and Ibu (alert level III) in Indonesia, and Mayon Volcano (alert level 1), Taal (alert level 1), Kanlaon (alert level 2), and Bulusan (alert level 1) in the Philippines reported recent volcanic activity according to Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) and the Philippine Institute of Volcanology and Seismology (PHIVOLCS).
OUTLOOK:
According to the ASEAN Specialised Meteorological Centre (ASMC), for the coming week, drier conditions are predicted over southern and eastern Mainland Southeast Asia, the Philippines, and southern Maritime Continent; while wetter conditions are predicted over much of the equatorial region. Warmer than usual temperature is predicted over much of southern and eastern Mainland Southeast Asia, the Philippines, and western and southern Maritime Continent. For the regional assessment of extremes, there is a moderate increase in chance for very heavy rainfall conditions to occur over parts of northern Myanmar and parts of the equatorial region; and a moderate increase in chance over the Philippines and southern Sumatra, and very likely over parts of southern Mainland Southeast Asia and southern half of Lao PDR for extreme hot conditions. La Niña conditions are expected to develop during August-September 2024 (ASMC).
