How Web Summit's Day 2 was called off
19:09 on Tuesday, and what led to it: a red warning before breakfast, a minister who said the venue was indoors, a mayor who said it could not run, water in a pavilion, a recommendation, and then a page on a path we were not watching.

Tuesday morning: the warning, and "um local fechado"
timeline rows-1110T0917evidencethe alert situation was announced in the morning: the Interior Minister at ANEPC's press conference, "o Governo decidiu declarar situação de alerta"; schools and non-essential services close. The government's page with the measures is timed 12:10 (the row above at 12:10); the minute he spoke is not established (09:14 is the earliest entry)Its source: observador.pt (leaves this site)
evidence Through the afternoon the storm was already at the venue, by the press's account: a thin audience at 15:19; at 17:07, water entering a pavilion between halls 4 and 5 and participants leaving early. d5
evidence At 17:53 the government's position had changed: it recommended suspending Web Summit on Wednesday ("Já emitimos a nossa recomendação de que os trabalhos desse evento possam suspender-se"), and left the decision with the organisers. That is 8 hours 23 minutes after the minister's "local fechado". d6

What it left open
fact On Thursdaythe organisers' own words are an aim: "Web Summit aims to proceed with Day 3 (Thursday, November 12) as planned, following the passing of Storm Charles". The press rendered it three ways: "conforme planeado" (RTP), "if the weather allows" (Diário de Notícias), and the page's own "aims to proceed". d11
fact The post was modified at 20:06 with its text on Day 2 and Day 3 unchanged, and by 21:53 there was no further statement. Still unannounced then: what happens to Wednesday's talks, the PITCH semi-final, side events and tickets. d12

factWeb Summit's own schedule had not caught up when it was read: the PITCH semi-final's page still showed "November 11, 2026 • 5.00PM - 6.00PM Centre Stage" with no word of the storm, and the schedule for 11 November still listed Wednesday's sessions, unmarked. d14

fact The warning this story begins with did not last to its own start: at 07:16:30 on Wednesday, with Day 2 already called off, IPMA lowered Lisbon's wind warning from red to orange, from 09:00 to 21:00, with gusts up to 120 km/h. The red rain warning for 09:00 to 18:00 stands. d15changed in the last telling
What passed between the government, ANEPC, PSP and the organisers, and when: the organisers' page speaks of the government's "direction"; the only time we have for the recommendation is the first press report, 17:53. Watched in graph.json
Why the minister's position at 09:30 and the government's at 17:53 differ: no source in the data room says. The red rain warning (sent 16:30) and the water at the venue (17:07) fall between them; nothing here says either was the reason.
The email to attendees has no public address: it is in this story only as relayed (evidence), at 19:38.
How this story has changed
The box at the top is now drawn from both of IPMA's channels, as the front page draws it: the newest message for each kind of weather, and what the open-data feed still lists where the two differ (before, it was drawn from the open data alone and showed red wind after IPMA's 07:16 message had lowered it to orange). The supports for Lisbon's red rain warning (09:00 to 18:00) now point at IPMA's kept message (PO-10-6290, sent 10 Nov 21:23) rather than the open-data list, which drops a warning when it ends; no sentence changed.
One sentence added: IPMA lowered Lisbon's wind warning from red to orange at 07:16:30 on Wednesday (row s-1111T0738). Nothing in the telling of Tuesday changes. Added: d15.
One sentence added from a new timeline row (s-1111T0255): Web Summit's schedule still lists Wednesday's sessions and the PITCH semi-final at 17:00 on 11 November, unmarked. Added: d14.
First telling, on the timeline (made 02:23 UTC) and the decision graph (updated 02:25 UTC): 13 sentences. Added: d1, d2, d3, d4, d5, d6, d7, d8, d9, d10, d11, d12, d13.
Every sentence above carries its label: fact (read from the body that decides or warns), evidence (reported by others, with the source) or hypothesis (analysis, with its confidence). Words said on air and not in a written record are marked said aloud; a model's output is marked a model; a sentence that sets two items of the data room side by side is marked our comparison and takes the weakest label among them.
Support under a sentence opens what it rests on: the timeline row, the field of the data file with the value it holds now, the decision edge; then the outside address, marked as leaving this site.
The switches show or hide sources, times, the hypothesis layer and what changed since the last telling. Nothing is removed from the data: story.json has all of it.
The page is rebuilt on every push from story.json by tools/stories-build.mjs. Each support is resolved again; if a field no longer says what a sentence was written on, the page says so beside that sentence.
