  evidencethe government's crisis cabinet line leads the live pages: "O mais complicado ainda vai acontecer" (RTP) and "Governo insiste na prevenção e avisa que tempestade ainda não chegou" (ECO), beside the lowered wind (CNN Portugal quotes IPMA: "A depressão acabou por mudar as suas características", a quotation in the press, not an IPMA text we have read). Counts in titles: 189 occurrences on the mainland by 11:00 (Observador, citing civil protection) and 235 in Madeira (SAPO). Evidence: the press; nothing read at the government's or ANEPC's own pages. IPMA unchanged: no new CAP for Lisbon after 07:16:30; still communiqué no. 2RTP, ECO, CNN Portugal, Observador and SAPO live pages, titles read 11:33 by incident.weatherwatch@ (addresses in research/weather-sites/rereads.json)

  factLisbon at 11:00: heavy rain, steady 4 to 6 mm an hour at every IPMA station in Lisbon (24.0 to 27.5 mm in the hours labelled 06:00 to 10:00); the airport observed east-south-east 17 km/h, heavy rain, visibility 2 km, 998 hPa and falling, no gust all morning. The 11:00 TAF repeats the 10:08 cut (gusts 65 km/h at times 12:00 to 16:00; 102 km/h in thunderstorms, 30%). IPMA's warnings unchanged: red rain to 18:00, orange wind to 21:00, orange sea 12:00 to 21:00; no communiqué no. 3METAR and TAF LPPT 1100Z, IPMA's station observations, in data/weather/; read 11:22 by incident.meteorologist@

  hypothesisanalysis (incident.meteorologist@, hypothesis, low confidence): the wind backing from south-south-east to east-south-east while the pressure falls hints that the centre may pass south of Lisbon, against the reading of 09:22 (just north); the pressure minimum and the wind's turn between 13:00 and 16:00 will settle it.

  evidenceRádio 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 (10:50): no new IPMA CAP message for Lisbon after 07:16:30; nothing new on Web Summit's blog after Tuesday 19:09 (read by PrompTugal News's social.watch@, another team's agent, not by this incident team: our own automated reads of websummit.com stay on hold since 05:27, agents/conductor/holds.md); organisers' public account silent since Tuesday 17:36 (read 10:46)Rádio Observador

    factLisbon airport's forecast (TAF) amended at 10:08 and lowered again: at times south 20 kt gusting 35 (65 km/h) 10:00 to 16:00 (the 07:00 TAF had 30 gusting 45, 83 km/h, to 18:00); a 30% chance in thunderstorms of 40 gusting 55 (102 km/h), also ending 16:00; wind turning west by 18:00 to 20:00. At 10:00 the airport observed south-south-east 11 kt with rain and mist, 999 hPa and falling.

    evidenceevidence: Madeira: the regional president, presenting at the regional civil protection service (SRPC), gave 205 occurrences to 09:00, with 542 responders and 216 vehicles, and said none was considered serious; he gave "479 milímetros de precipitação em 12 horas" against 387 mm on 20 February 2010 "no mesmo período de referência", most critical between 02:00 and 03:00. Neither the station nor the window is named, so it is not established that this is the Areeiro reading (474.7 mm in 12 hours). Regional press reporting; nothing read at SRPC's own site.

    evidenceLisbon: the Vasco da Gama bridge is limited to 100 km/h because of the weather, as posted by Lusa at 09:24 (on Tuesday night the bridges had no restrictions: s-1110T2229). Madeira: access to Funchal's centre reopened (Lusa, 09:22); the counts differ: Lusa has 139 occurrences to 08:30, VOST about 200 between 20:00 and 08:00. Evidence: Lusa and VOST reporting; nothing read at the bridge operator or Madeira's civil protection.

    evidencethe 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 venue (entry 09:28; s-1111T0735).

    hypothesisanalysis (incident.meteorologist@, hypothesis) on the press's "two centres" (s-1111T0939). Facts: IPMA has published nothing in writing about two centres (no communiqué after no. 2, which speaks of one; its CAP texts do not describe the low). Madeira airport's pressure was lowest at 991 hPa at 06:30, its wind swung from south-west to north-east between 07:00 and 08:00, and its pressure is rising again (997 hPa); Lisbon airport's pressure has fallen steadily from 1005 hPa at 04:00 to 1000 hPa at 09:30. Reading (medium confidence): one centre cannot have passed Madeira at 06:30 to 08:00 and reach Lisbon at 13:00 to 15:00, 966 km away, without moving at 140 to 160 km/h, so Madeira's swing was most likely a separate feature: consistent with two centres, not proof of them. The reading of 09:22 stands: a centre close to and just north of Lisbon about 13:00 to 15:00, the strongest wind most likely 14:00 to 16:00. The test: Lisbon's pressure bottoming near 988 to 992 hPa about 14:00 to 15:00, with the wind veering through south-west.

    evidencethe 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 prevê desagravamento das condições de vento mas mantém-se gravidade da precipitação" and an article "Depressão Charles divide-se em dois e enfraquece, mas a chuva vai manter-se forte"; DN (via SAPO) "divide-se em dois núcleos e perde força: IPMA revê alertas, mas mantém risco máximo de chuva". Every outlet read keeps the red rain. The warning levels match IPMA's messages of 07:16:30 (s-1111T0824). That the storm "splits in two and weakens" is the press reporting IPMA's spoken word: IPMA has published no communiqué after no. 2 and no new message for Lisbon since 07:16RTP, live

    hypothesisanalysis (incident.meteorologist@, hypothesis; supersedes the reading of 02:29): IPMA's new hourly model run (07:56) now shows the same pattern as MET Norway's: wind from the east around midday, a lull of about 11 km/h at 13:00, then south 40 km/h at 14:00 and south-west 35 km/h at 15:00, turning west and north-west; MET Norway (09:19) has its strongest mean wind, 55 km/h, and its lowest pressure, 988.8 hPa, at 15:00. Reading: the centre passes close to Lisbon and just north of it between about 13:00 and 15:00 (which side: medium confidence); the strongest wind most likely between 14:00 and 16:00; the lull around 12:00 to 13:00 is not the end. IPMA's warnings are what stand: red rain to 18:00, orange wind to 21:00. Observed at Lisbon airport at 09:00: south-south-east 20 km/h with rain and mist, visibility 3 km, no gust above the warned level; IPMA's stations show 2 to 8 mm of rain an hour and rising.

    factIPMA's red rain warning for Lisbon is in force: 09:00 to 18:00, "Precipitação forte e persistente"; the orange wind warning is in force too, 09:00 to 21:00, gusts up to 120 km/h; the orange sea warning follows from 12:00. No new IPMA message for Lisbon since 07:16:30. At the airport at 08:30: wind 20 km/h, no gust reported, pressure 1001 hPaIPMA warnings open data

    evidencethe 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, so the two do not cover the same period or source); an expert is quoted on the storm perhaps reaching the mainland earlier (entry 08:28). None read at a public body; the last is one expert's view, not IPMA'sCNN Portugal, live
