The March 2026 flood, week by week, in community reports

Covers February through April 2026 · published 2026-07-08 HST

March 2026 was the highest community-reporting month in the covered year: 1,164 reports islandwide, against a next-highest month of 723. Much of the difference was the storm and flood. This is the weekly arc, from the record that combines the live reporting pipeline and the historical SSH community archive.

The arc, week by week

Weather and emergency reports (flooding, road water, evacuations, outages) ran at baseline through the week of March 2, with a single report islandwide. The week of March 9 logged 166; the week of March 16 logged 115; the week of March 23 fell to 21; and by the week of March 30 the count was back under 5. Traffic-incident reporting moved with it on a smaller scale: 32 in the week of March 2, then 44 and 47 across the two flood weeks, then 23 the following week. March's weather-and-emergency reports totaled 303 for the month, nearly five times the next-highest month in the covered year (62).

What the reports were

Across the two peak weeks (March 8 through 22), the weather-and-emergency reports broke down as weather alerts and warnings (171), power outages (42), flood reports (35), emergency alerts (9), and evacuations (8), with the remainder spread across smaller categories.

What was deliberately not counted

Alongside the incident reports, the community carried a heavy volume of mutual-aid coordination through those weeks: donation drives, shelter and supply questions, road-condition questions, and gratitude posts. During the historical-archive review each of those posts was read individually and excluded from incident counts. The figures above describe incident reporting, not total community activity, which the counts do not include.

After the water

April's community total settled at 649, within the range of the months before the storm. The flood remains visible in the year's records as a two-week signature: one category group moving two orders of magnitude while the official crime record for March (2,359 recorded incidents) stayed inside its usual band, a reminder that the two records measure different things.

How to read this. Everything we publish is descriptive: what was recorded, reported, noticed, and sought, in a stated past period, with caveats. Figures are aggregate and de-identified; person-linked counts under 5 are suppressed; per-capita rates use daytime population with 95% confidence bands. Never a forecast, score, ranking, or safety judgment. Full detail: the methodology page.
