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.

What changed

Updated verified snapshot

This record was first dated 2026-08-18 and last verified 2026-10-06.

Situation

GDACS event FL 1104122 now records a national multi-episode aggregate of six deaths and 627 displaced people across the broader period from 18 August to 3 October 2026. This is two additional deaths and 458 additional displaced people compared with the retained 27 September snapshot. The source does not establish that these additional impacts occurred on 3 October, so they are treated as a revised cumulative aggregate rather than fresh same-day casualties or displacement.

The earlier two-death, three-death, four-death and 169-displaced observations remain preserved below. Thai Department of Disaster Prevention and Mitigation reporting corroborates continuing flood-response activity. The aggregate spans multiple episodes, provinces and observation dates, so it must not be treated as the denominator for one single flood incident. Figures remain provisional as water levels, returns and government assessments are reconciled.
