Tropical Storm ONE-26 exposure estimate revised to 10.248 million in India
Tropical Cyclone A
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
GDACS classified Tropical Cyclone ONE-26 as an Orange alert with medium humanitarian impact after the system crossed India between 23 and 24 September 2026. The storm reached maximum sustained winds of 83 km/h. On 28 September, GDACS revised its modelled tropical-storm-strength wind exposure from up to 10.7 million to 10.248 million people. No population was modelled in Category 1 or stronger winds. A maximum storm surge of 0.7 metres was modelled near Bideipur on 22 September.
The exposure figure describes people within the modelled wind footprint; it is not an observed affected, displaced or casualty total. No verified casualty figure is promoted in this record. The event period was 22-24 September and the alert remains an impact-screening signal pending any later authoritative field assessment.

WorldsAid verification
A WorldsAid editor reviewed this record against 1 attributed source, cleaned feed formatting and checked the crisis, place and reporting date. 7 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.
