Situation
Thailand's 2026 monsoon flooding has moved beyond monitor-only status. GDACS event FL 1104122 now records a national multi-episode aggregate of three deaths and 169 displaced people across the broader period from 18 August to 26 September 2026. This is one additional death compared with the 19 September snapshot. The source does not establish that the additional death occurred on 26 September, so it is treated as a revised cumulative aggregate rather than a fresh same-day casualty.
The earlier two deaths were reported in Nan Province during August and 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.
