Resource details

Summary: Three public alert records attributed to DHM, retained from a national startedOn-filtered search. Alert start, database creation, expiry and later embedded observations remain distinct. These records do not establish delivery, receipt, evacuation or a complete issuance history.
Review findings: Automated metadata assessment; independent human eligibility and manuscript inclusion remain unassigned. No component-specific open licence established. Public API access does not establish redistribution permission. Only descriptive metadata and source links are published; retrieved source responses remain private.

Preserve alert start, database creation and embedded observation times separately; obtain archived issuance/update evidence before reconstructing the warning timeline.
Keep the description water level separate from the later embedded reference measurement; they are not a single issuance-time observation.
Establish component-specific reuse terms before redistributing upstream observations or alert contents.

Public BIPAD alert attributed to DHM. Its stated start is 2026-08-25T21:10:00+05:45; database creation is 2026-08-25T21:15:09.946486+05:45. The embedded reference observation is 2026-08-25T16:15:00Z, 50 minutes after the alert start. Description and embedded reference water levels differ. These fields must not be combined into one issuance-time measurement. Expiry is 2026-08-25T22:15:04.284556+05:45; expiry is not a proven return to safe conditions.
No component-specific open licence established. Public API access does not establish redistribution permission. Only descriptive metadata and source links are published; retrieved source responses remain private.
Public access and structural inspection do not establish scientific accuracy; station points and alert demography are not a measured flood footprint or affected-person count.
