Severity score45 / 100 · Moderate

How the score is calculated

The score starts at 8. It adds points from recorded affected, deaths, displaced and casualty counts, plus terms found in the story title, event type or status. For each count, only its highest matching band is used.

Affected people: 1–999: +5 · 1,000–9,999: +12 · 10,000–99,999: +20 · 100,000–999,999: +28 · 1 million+: +35
Deaths: 1–9: +8 · 10–99: +14 · 100–999: +22 · 1,000+: +30
Displaced people: 1–9,999: +6 · 10,000–99,999: +12 · 100,000+: +18
Casualties: 100 or more: +8
Story wording: +10 for terms such as catastrophe, famine, war, conflict, major earthquake, mass casualty or critical. Otherwise, +5 for active, ongoing, emergency, outbreak, cyclone or hurricane.

Score bands: Watch 0–24 · Moderate 25–49 · High 50–74 · Critical 75–100. Scores are capped at 100. Missing or unparseable figures add no points.

Situation

Sustained monsoon rain pushed rivers above danger levels across low-lying parts of Myanmar's Ayeyarwady Region. A breached embankment near Myit Kyo Village on 30 July sent water into Laymyatna and surrounding settlements, damaging homes, farmland, roads and public infrastructure. Red Cross reporting identified impacts across 169 villages in Laymyatna, Yegyi and Hinthada townships. About 28,455 people from 8,907 households moved to 28 evacuation sites. Separately, GDACS event FL 1104011 reports a national multi-episode aggregate of 15 deaths and 10,393 displaced people across 4 July to 16 September 2026. That national aggregate is retained as a scope-separated observation and is not added to, subtracted from or treated as a revision of the Ayeyarwady figures. Broader NUG reporting of 25 deaths, two missing and more than 440,000 affected, UNICEF's estimate of about 600,000 affected by the end of August, and September local reports from Kale Township and Monghsu use different geographies, periods and definitions and are therefore not arithmetically merged.

A separate GDACS national multi-episode observation through 2 October reports 18 deaths and 11,013 displaced; this remains distinct from the Ayeyarwady event figures above and supersedes only the earlier 28 September GDACS national snapshot of 18 deaths and 10,993 displaced. GDACS episode reporting for Tanintharyi on 26–28 September separately records three deaths, 10 missing and 500 displaced. These scopes are not added together.

Local Launglon reporting remains provisional and conflicting: Global New Light of Myanmar cites rescue workers reporting around 10 deaths and nearly 20 missing, and officials saying 8,431 flood victims from four wards were relocated to Pan Taw Wa Monastery. An AFP report on 28 September separately said eight bodies had been recovered and 20–30 people were missing. A later AFP report dated 30 September narrowed its scope to the Ka Det Nge Htein village landslide, where a local emergency-service team reported nine bodies recovered and eight people still missing. These local statements are preserved as source- and date-specific observations and are not reconciled arithmetically with each other or with GDACS.

WorldsAid verification

A WorldsAid editor reviewed this record against 8 attributed sources, cleaned feed formatting and checked the crisis, place and reporting date. 13 human-impact figures were separated from the narrative and dated where the source allowed. Earlier observations remain in the evidence history instead of being silently overwritten.
