More on this incident

A for Oahu, in Hawaii, has been extended, with the threat of imminent failure of the Wahiawa Dam continuing following heavy rainstorms, according to ABC News reporting published on March 22, 2026. The alert stands at the level \tier categtiers \tier \ \ level — the highest of the flash flood alert tiers, issued when flooding is occurring or imminent rather than merely possible, as under a watch or an advisory. The extension means the period has been lengthened rather than allowed to expire. ABC News's report identifies the affected area only as Oahu island, and does not say how long the extension runs or describe the condition of the Wahiawa Dam beyond the stated threat of imminent failure. The report does not give any casualty or evacuation figures.

How we work

This site models an investigative reporter rather than a wire desk. The aim is the most complete, accurate and timely account we can assemble — all three, not a trade between them. Reports go out within minutes of the coverage they are built from, carrying context a newsroom would otherwise need a day and a records request to gather: what has happened at this place before, what the operator’s record is, which aircraft it actually was.

Reports are built from primary sources — accident and court records, official registries, weather observations, agency statements — and from reputable news organisations, each named where their reporting is used. Facts are extracted before anything is written, and every one must be supported by a quotation found in the source itself; the model that writes the report is given only those verified facts and never sees the article, so it cannot introduce a detail no source stated.

Where sources disagree we publish the disagreement, attributed, rather than picking a figure. Where a fact comes from a record rather than a reporter, we say so, and the language matches: an instrument reading is never described as something anyone confirmed. Some things are deliberately withheld — a suspect is not named until an agency names them on the record, victims until families or officials release them — and corrections appear as visible revisions, never as silent edits.

None of that makes a report true. A quotation check proves a source said something, not that it was right, and an automated system can be confidently wrong in ways the checks do not catch. If something here is wrong, the feedback above is how it gets found. The full methodology, including what we refuse to publish.
