How Web Summit's Day 2 was called off (as text)

Kept by incident.stories@web-summit.dinis, 11 November 2026, 07:57 UTC

Not a warning service. For warnings follow IPMA and ANEPC. This page makes no forecast and gives no advice of its own.

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.

State: developing. Written 11 Nov, 02:33 UTC on the data read at 11 Nov, 07:38 UTC. The page with toggles: index. The graph: story.json.

IPMA's red warnings for the Lisbon district

Both channels are IPMA's; for each kind of weather this shows the newest message by the time IPMA sent it, and no level of our own. Kept in cap.json (IPMA's messages, CAP, as MeteoAlarm relays them; read 11 Nov, 11:26 UTC) and warnings.json (IPMA's open-data feed; read 11 Nov, 11:26 UTC).

Tuesday morning: the warning, and "um local fechado"

Tuesday afternoon: the mayor, the water, the recommendation

  • evidence d4 At 13:19 Lisbon's mayor said "Tudo indica que a Web Summit não poderá funcionar amanhã", and that the decision was the Interior Ministry's and the organisers'.
    Lisbon's mayor, as reported by Jornal Económico; said or sent 10 Nov, 13:19 UTC; read 10 Nov, 18:45 UTC. Support: row s-1110T1319 (evidence); decision edge mayor-expects-closure in graph.json.
  • evidence d5 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.
    Jornal de Negócios, live blog; said or sent 10 Nov, 17:07 UTC; read 10 Nov, 18:50 UTC. Support: row s-1110T1519 (evidence); row s-1110T1707 (evidence).
  • evidence d6 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".
    the Government, as reported by Jornal de Negócios' live blog (no government page was found); said or sent 10 Nov, 17:53 UTC; read 10 Nov, 18:58 UTC. Support: row s-1110T1753 (evidence); graph.json edges[id=gov-recommends-suspend].decision; row s-1110T0930 (evidence).
  • fact d7 For more than an hour nothing came from the organisers: no statement at 18:25, none at 18:53, and at 19:05 no decision on their home page, news list, sitemap or official Bluesky.
    this site's desks, reading Web Summit's channels (the 18:25 and 18:53 reads are of press pages: evidence); said or sent 10 Nov, 19:05 UTC; read 10 Nov, 19:05 UTC. Support: row s-1110T1825 (evidence); row s-1110T1853 (evidence); row s-1110T1905 (fact).

19:09

What it left open

  • fact d11 On Thursday the 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".
    Web Summit, "Important event update" (the renderings are evidence: RTP, Diário de Notícias); said or sent 10 Nov, 19:09 UTC; read 11 Nov, 01:36 UTC. Support: decision edge websummit-thursday in graph.json; row s-1110T1946 (evidence); row s-1110T1949 (evidence); incident.json thursday.
  • fact d12 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.
    Web Summit's blog listing, as watched; this site's desks; said or sent 10 Nov, 21:53 UTC; read 11 Nov, 01:36 UTC. Support: row s-1110T2132 (fact); row s-1110T2153 (fact); decision edge websummit-n6 in graph.json.
  • fact d14 Web 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.
    Web Summit's schedule pages, as read; said or sent 11 Nov, 02:55 UTC; read 11 Nov, 02:55 UTC. Support: row s-1111T0255 (fact); decision edge pitch-semifinal in graph.json.
  • fact d15 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.
    IPMA, warnings (a CAP message through MeteoAlarm); said or sent 11 Nov, 07:16 UTC; read 11 Nov, 07:38 UTC. Support: row s-1111T0738 (fact); cap.json lisbon_messages[identifier=2.49.0.0.620.0.PT.261111071630.PO-01-1932].event_pt; cap.json lisbon_messages[identifier=2.49.0.0.620.0.PT.261111071630.PO-01-1932].sent_utc; cap.json lisbon_messages[identifier=2.49.0.0.620.0.PT.261111071630.PO-01-1932].onset_utc; cap.json lisbon_messages[identifier=2.49.0.0.620.0.PT.261111071630.PO-01-1932].expires_utc; cap.json lisbon_messages[identifier=2.49.0.0.620.0.PT.261111071630.PO-01-1932].description_pt; cap.json lisbon_messages[identifier=2.49.0.0.620.0.PT.261110212300.PO-10-6290].onset_utc.

What is not known

  • 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.
  • 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.
  • What happens to Wednesday's talks, the PITCH semi-final, side events and tickets: unannounced at our last read.
  • Whether Day 3 runs: the organisers' word is "aims". For that, the page itself and IPMA's warnings for Thursday.
  • 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

  • 11 Nov, 07:57 UTC: 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.
  • 11 Nov, 07:53 UTC: 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.
  • 11 Nov, 03:28 UTC: 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.
  • 11 Nov, 02:33 UTC: First telling, on the timeline (made 02:23 UTC) and the decision graph (updated 02:25 UTC): 13 sentences.
