| 11 Nov, 11:09 UTC | evidence | Rádio Observador (10:38) reports the overnight reassessment moved Charles's track further south, toward the Algarve, with heavy rain in Lisbon about 11:00 to 15:00 easing after about 18:00 (the press, not IPMA's written word; consistent with Faro keeping red wind, s-1111T0824). At the same sweep (10… |
| 11 Nov, 09:55 UTC | evidence | the cancellation reaches the international trade press: Deadline, "Web Summit Cancels Day Two As Storm Charles Hits Lisbon" (posted 09:10). In Lisbon, CNN Portugal's live blog: the riverside almost empty with access restricted (entry 09:20) and photos of cars partly submerged at Oriente, next to the… |
| 11 Nov, 09:39 UTC | evidence | the press now reports IPMA's wind change, and attributes more to IPMA than IPMA has written. Titles read: Observador's live blog "Vento. IPMA reduz nível de alerta em Lisboa, Setúbal e Beja"; TSF "Previsões do IPMA melhoram: apenas Faro está sob aviso vermelho para vento"; RTP's live blog "IPMA prev… |
| 11 Nov, 08:51 UTC | evidence | the press on the morning ahead (CNN Portugal's live blog): intense rain may coincide with high tide and hinder drainage in the big cities (entry 08:27); civil protection counted 60 incidents by 06:00, Greater Lisbon the most affected with 26 (entry 08:26; the count for 03:30 reported earlier was 66,… |
| 11 Nov, 08:44 UTC | fact | IPMA's open-data feed now agrees with its 07:16:30 message: Lisbon's wind warning is orange, 09:00 to 21:00, "Rajadas até 120 km/h."; the red wind entry is gone (it was still listed at 08:22). The feed followed the message by between 66 and 88 minutes. Red rain 09:00 to 18:00 stands; the orange rain… |
| 11 Nov, 08:22 UTC | fact | Observed at the airports at 08:00. Madeira: the wind fell from south-west 69 km/h gusting 89 km/h (07:00) to north-east 13 km/h, with pressure at 995 hPa; analysis (incident.meteorologist@, hypothesis): the storm's centre passed close to Madeira airport between about 07:30 and 08:00. Lisbon: south-s… |
| 11 Nov, 06:42 UTC | fact | Checked: the "winds of 130 km/h in Madeira" in press headlines (SAPO's front page, read 06:39; Lusa, 06:37, "Charles causou ventos de 130 km/hora na Madeira") matches the figure in IPMA's warning text, and no such observation is in IPMA's open data. Lusa's article (published 06:28, read 06:37 by inc… |
| 11 Nov, 03:28 UTC | evidence | RTP's 03:00 radio bulletin is titled "IPMA: depressão Charles vai atingir mais o sul do país" (the title only; the bulletin was not listened to). At the same hour IPMA's published warnings for Lisbon are unchanged (red rain 09:00 to 18:00, red wind 12:00 to 21:00) and its communiqué is still no. 2; … |
| 11 Nov, 02:55 UTC | fact | Web Summit's own schedule, as read: the PITCH semi-final's session page still reads "November 11, 2026 • 5.00PM - 6.00PM Centre Stage", with no word of the storm, and the schedule for 11 November still lists Wednesday's sessions (62 pages), unmarked. So the semi-final's original slot was Wednesday 1… |
| 11 Nov, 00:29 UTC | evidence | the press now reports the track further south and a weaker wind: Público's live blog headline "Charles passa mais a sul do que o previsto e vento deverá ser menos intenso"; Observador "IPMA admite que Charles entre mais a sul do que o previsto"; Notícias ao Minuto "Tempestade muda de trajetória; CP … |
| 10 Nov, 23:50 UTC | evidence | (unofficial, unverified) a public weather page on Facebook shows the storm's track further south than first forecast, toward Lisbon and just south of it; the image is undated and the page is not IPMA. To compare with IPMA's next communiqué; IPMA's own text keeps "entre Sines e o Cabo Carvoeiro" with… |
| 10 Nov, 23:24 UTC | hypothesis | analysis (incident.meteorologist@, labelled): the TAF's peak (09:00 to 16:00) and IPMA's model peak (19:00 to 20:00) disagree, so the peak is widened back to 12:00 to 18:00; end 21:00; Thursday morning behind the storm, medium confidence; a weaker airport forecast is not a downgrade of IPMA's warnin… |
| 10 Nov, 19:49 UTC | evidence | Thursday resumes "if the weather allows" (DN's wording; RTP's "as planned, after the storm"; the organisers' own page: "aims to proceed") |
| 10 Nov, 19:46 UTC | evidence | organisers will hold Thursday "conforme planeado, após a passagem da tempestade Charles"; people affected will be contacted directly |
| 10 Nov, 19:09 UTC | fact, decision | PRIMARY: Web Summit's own page, "Important event update": "Day 2 (Wednesday, November 11th) will not take place"; "Web Summit aims to proceed with Day 3 (Thursday, November 12) as planned, following the passing of Storm Charles"; reasons: tidal flooding, disruption to public transport, high winds on… |
| 10 Nov, 17:07 UTC | fact | IPMA communiqué no. 2 on CHARLES (edited 17:07:58): worse weather from early Wednesday morning; the centre most likely to pass "entre Sines e o Cabo Carvoeiro"; gusts 100 to 120 km/h, locally 140; "elevada incerteza" in track and strength |
| 10 Nov, 17:00 UTC | fact | Dinis: the storm is our case study (a dynamic team, the decision graph) |
| 10 Nov, 15:19 UTC | evidence | the storm leaves Web Summit with a thin audience |
| 10 Nov, 08:46 UTC | evidence | IPMA expects the storm earlier, Wednesday morning; Lisbon among the hardest hit; avoid unnecessary travel (Lusa) |
| 9 Nov, 20:30 UTC | fact | ANEPC's public warning, Aviso 21, on CHARLES (before any red warning) |
| 9 Nov, 13:17 UTC | fact | IPMA names the storm CHARLES (communiqué no. 1): expected north of Madeira at 00:00 on 11 Nov, then toward the mainland, "com elevada incerteza na trajetória e intensidade"; orange warnings to be issued |
| 9 Nov, 10:20 UTC | evidence | AEMET, Spain's meteorological agency, says in public that the storm is named Charles, 2 h 57 min before the 13:17 this timeline gives for IPMA's communiqué no. 1 (row s-1109T1317). AEMET's post is timed 10:20:11 (read through Bluesky's public API). IPMA's communiqué no. 1 can no longer be read (its … |
