| 11 Nov, 11:28 UTC | fact | Lisbon 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 (gust… |
| 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, 10:28 UTC | fact | Lisbon 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:… |
| 11 Nov, 09:22 UTC | hypothesis | analysis (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 we… |
| 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, 07:27 UTC | fact | Madeira, observed: 249.5 mm of rain in six hours at IPMA's station Areeiro, its largest six consecutive hourly values so far (was 232.1 mm at the 04:23 read); this is the measurement behind the "more than 240 mm in six hours" an IPMA meteorologist gave Lusa (s-1111T0642). Madeira airport at 07:00: w… |
| 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, 06:25 UTC | fact | Madeira's red warnings ended at 06:00, as IPMA had scheduled: its warnings page now shows orange as the highest level for Madeira's north coast, mountain regions and south coast (red at the 05:23 read); in its open data the red rain (all three areas, from 21:00 Tuesday) and the mountains' red wind c… |
| 11 Nov, 05:22 UTC | fact | Lisbon airport's forecast issued at 05:00 lengthens the strong wind by two hours: at times 30 kt gusting 45 (83 km/h) from 09:00 to 18:00 (the 23:00 forecast had it to 16:00); the 30% chance of thunderstorm gusts of 58 kt (107 km/h) stays 10:00 to 18:00; west 12 kt from 18:00 to 20:00. Observed at 0… |
| 11 Nov, 04:37 UTC | evidence | the first count for the mainland: 66 occurrences at 03:30, reported by Lusa (carried by Notícias ao Minuto, 04:01, and on SAPO's front page) as civil protection's figure. Title read only; no count read at ANEPC itself, whose notice is still no. 21. IPMA unchanged at the same hour (communiqué no. 2; … |
| 11 Nov, 01:46 UTC | fact | Madeira, observed: 230.5 mm of rain in six hours at IPMA's station Areeiro (the hours 20:00 Tuesday to 01:00 Wednesday; 133.9 mm in the six hours to 22:00); next: Santo da Serra 124.4, Pico do Areeiro 123.9, Pico Alto 116.7 mm in six hours |
| 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, 23:53 UTC | fact, decision | IPMA moved Lisbon's red rain warning three hours earlier: Wednesday 09:00 to 18:00 (was 12:00 to 18:00; supersedes s-1110T1742); orange rain now 00:00 to 09:00; red wind unchanged (12:00 to 21:00). IPMA sent the change at 21:23 (its CAP message); its open-data feed showed it only from the 23:51 read |
| 10 Nov, 18:36 UTC | fact | Vicky's weather desk full check: IPMA's two red warnings for Lisbon unchanged since 17:42 (wind 12:00 to 21:00, rain 12:00 to 18:00); no Web Summit change |
| 10 Nov, 17:42 UTC | fact, decision | IPMA raises Lisbon's rain warning to red, Wednesday 12:00 to 18:00 (IPMA sent it at 16:30:01, by its CAP message; 17:42 is when the weather desk first read it) |
