head: --- # Weather pages, annotated > Kept by incident.weatherwatch@web-summit.dinis, 2026-11-11T03:41:00Z UTC 12 pages from 9 countries and services, each with numbered callouts on the page as we drew and saw it (1280 x 1600 px, the top of the page). At Dinis's word of 11 November, ~02:20 UTC: "take a screenshot of a website and then you start pointing". The screenshots are incident.archivist@'s captures: six are read in your browser from the display vault and checked against their sha256 (never kept in git), and each point was checked to sit on its part (the Met Office's is shown with its cookie-consent panel hidden, and says so); four are kept privately because the site's terms do not clearly allow showing them, and there the frame stays empty with the numbers where the parts are. Data: [index.json](index.json) and one file per study.

Hazard, level, period, and what to expect. | `data/`weather/warnings.json (type, level, start_utc, end_utc, text_pt) | | 4 | Every district with its highest level | A list on the right: the district's name and a chip ("Vermelho", "Laranja"); the one shown is marked. | warnings.json (red_and_orange_elsewhere) | | 5 | UTC, and the last update | "Toda a informação em horas UTC" and "Última atualização: terça, 10 de novembro de 2026 às 21:23". | read_utc; cap.json (sent_utc) | | 6 | The criteria, linked | "Critérios de emissão": what makes a warning yellow, orange or red. | a link; thresholds for the legend of our strip | May the screenshot be shown: IPMA: free use for personal or public purposes that are not for profit, with the source named, its logo and a link (imagery.json): a screenshot with "Fonte: IPMA" fits if the site is non-profit (a question open with Dinis).

IPMA: hourly forecast for a place (Lisboa) (Portugal)

(leaves this site) · seen 2026-11-10T23:48Z · [our page about the site](../sites/ipma-local.md) · [data](ipma-hourly.json) The page our hour strip should learn most from: day tabs that carry the warning colour, and an hourly table whose last row is the warnings themselves. | No. | Part | What it does well | Fed on our site by | |---|---|---|---| | 1 | When it was made | "Informação em horas UTC. Última atualização: 2026-11-10 19:56:03 (UTC)". | `data/`weather/forecast.json (hourly_runs) | | 2 | The day tab carries the warning | Under each day: min, max, wind, rain probability, and a label in the level's colour ("Amarelo", "Vermelho", "Amarelo"). | `data/`weather/forecast.json (daily) + warnings.json | | 3 | Rain probability by three-hour block | "100%" across the morning and afternoon of Wednesday, "24%" at the end. | `data/`weather/forecast.json (hourly) | | 4 | Mean wind, hour by hour | An arrow, a figure in km/h and a direction per hour: 11 to 23 km/h. This is the automatic mean wind, not the gust the warning speaks of. | `data/`weather/forecast.json (hourly); label it "automatic, mean wind" | | 5 | The warnings as a row of the table | "Avisos Meteorológicos": one cell per hour, yellow, then orange, then red from 09H to 21H. The best row on the page, placed last. | `data/`weather/warnings.json: on our strip this row goes first | | 6 | The caveat, in the notes | The page explains that this automatic forecast may differ from the forecasters' descriptive forecast and from the warnings, which should be consulted. True and far from the numbers it qualifies. | a one-line note beside our model rows | May the screenshot be shown: As IPMA above.

Yr: Lisbon, hour by hour (Norway)

(leaves this site) · seen 2026-11-10T23:48Z · [our page about the site](../sites/yr.md) · [data](yr-lisbon.json) A foreign public service that shows the local authority's warnings, in English, above its own hours. | No. | Part | What it does well | Fed on our site by | |---|---|---|---| | 1 | Warnings with a status word | Five banners for Lisboa: "Ongoing: Yellow Coastal Event Warning", "Expected: Orange Rain Warning", "Expected: Red Rain Warning", "Expected: Red Wind Warning", "Expected: Orange Coastal Event Warning". Each opens for the text. | `data/`weather/warnings.json (status from start_utc and end_utc against now) | | 2 | The calm table | Time, symbol, temperature, precipitation in mm, wind in m/s with an arrow. No decoration. | `data/`weather/forecast.json (hourly, second_models) | | 3 | Wind in words | "Fresh breeze from south east": a reader who does not think in metres per second still understands. But the words describe the automatic mean wind under a red wind warning, and the page does not say so. | the warning's own text beside any model wording | | 4 | Sunrise and sunset | One line under the table. | not held | | 5 | Previous day, next day | Two buttons; the table is one day at a time. | our strip: Wednesday, then Thursday | May the screenshot be shown: MET Norway data is NLOD / CC BY 4.0; the page design is Yr's. The archivist confirms before the screenshot is shown.

MeteoAlarm: Portugal (Europe)

(leaves this site) · seen 2026-11-10T23:48Z · [our page about the site](../sites/meteoalarm.md) · [data](meteoalarm-portugal.json) Every national service's warnings in one format: a map, a time bar and a list. | No. | Part | What it does well | Fed on our site by | |---|---|---|---| | 1 | The country by warning area | Districts in yellow and orange on the mainland, Madeira in red, at the hour chosen. | our own redraw from IPMA's JSON (never a copy of this map) | | 2 | Now, +24h, each day, animation | A row of buttons under the validity window "Tu 2026.11.10 23:00 - We 2026.11.11 02:00 (GMT+0)". | `data/`weather/warnings.json | | 3 | Short-term and long-term hazards | Tabs that separate wind, rain and coast from slower hazards. | warnings.json (type) | | 4 | Filters by level and by hazard | Two lists. | the same | | 5 | One row per warning | The hazard's pictogram on its level's colour, then the area: Lisboa appears three times, once per warning. | `data/`weather/cap.json (each message) | May the screenshot be shown: MeteoAlarm's maps, icons and layout belong to EUMETNET and are licensed to its participants only (its terms): the screenshot is not shown unless the archivist finds a basis; the link stands.

KNMI: warnings (Netherlands)

(leaves this site) · seen 2026-11-11T02:17Z · [our page about the site](../sites/knmi.md) · [data](knmi-warnings.json) Seen on a quiet night: what a warnings page says when there is nothing to warn about, and where it puts "what can I do". Limits: No warning was in force in the Netherlands, so the page in use was not seen. | No. | Part | What it does well | Fed on our site by | |---|---|---|---| | 1 | The state in one plain line | "Er zijn geen waarschuwingen" (there are no warnings), as a line of text above the map, and again as a heading. | warnings.json (when nothing is in force, say so in words) | | 2 | A quiet map | The country with no colour at all when nothing is in force. | our own redraw | | 3 | What it warns for | One sentence listing the hazards KNMI warns about. | a line in our legend: the eight hazards IPMA warns for | | 4 | What can I expect and what can I do | One link per hazard: thunderstorms, heavy gusts and storm, snow, ice, heavy rain, cold, heat. | ANEPC's measures per hazard, quoted and linked | May the screenshot be shown: KNMI states the Creative Commons zero declaration (CC0) for its website content unless marked (its copyright page): the screenshot may be shown.

US National Weather Service: the national hazards map (weather.gov) (United States)

(leaves this site) · seen 2026-11-11T03:39Z · [our page about the site](../sites/nws.md) · [data](nws-hazards-map.json) The front page of a national service is its hazards map: every county and every coastal water of the country, coloured by the hazard in force, with the time the map was made printed on the map and a legend that lists only the hazards in force. Above it, the day's national headline in three sentences. Colour here means the kind of hazard, not how severe it is. Limits: Colours are by kind of alert (a gale warning, a flood advisory), so the map does not show at a glance which is the most severe. No alert was opened. | No. | Part | What it does well | Fed on our site by | |---|---|---|---| | 1 | The national headline, in words | "Storm System to Move Across the Ohio Valley to the Mid-Atlantic and Northeast", then two sentences and "Read More": the forecasters' own summary sits above every map. | `data/`weather/communiques.json (the current communiqué's subject and first sentence, quoted) | | 2 | One row of doors | Active alerts, forecast maps, radar, rivers and rainfall, air quality, satellite, current: seven words, each a view of the same country. | our own data room's sections | | 3 | The time is on the map | "Created: 11/11/26 at 03:38 UTC" is drawn inside the image, so a copy of the map carries its own time. | `data/`weather/warnings.json (read_utc), drawn inside our own strip and map | | 4 | Everything in force, on one map | Counties and marine zones are white until something is in force; a click on any of them opens the alerts for that place. | our own redraw from IPMA's JSON; district shapes from an open source | | 5 | A legend of what is in force only | Eighteen kinds of alert were listed at this read, each a link to its own list: the legend is built from the map, not printed whole. | `data/`weather/warnings.json (the levels and hazards present at this read) | | 6 | The same as data, under the map | "Public Alerts in XML/CAP v1.2 and ATOM Formats": one link, directly beneath the picture. | api/v1/index.json and the warnings file's own address | May the screenshot be shown: US government work, public domain (third-party map tiles excepted): a screenshot may be shown.

DWD: warnings by municipality (Germany) (Germany)

(leaves this site) · seen 2026-11-11T03:39Z · [our page about the site](../sites/dwd.md) · [data](dwd-warnings.json) The state of the country in two words in the header of every page ("KEINE UNWETTERWARNUNG"), a map down to the municipality with the time it was last updated above it, a legend with the four levels in words, and under it the warning situation written out and timed by the forecasting centre. On this night it showed level 1 (yellow) over parts of the north and east and nothing higher. Limits: No severe-weather warning was in force in Germany, so levels 2 to 4 and a warning's own text were not seen. At the first attempt (11 November, about 02:50 UTC) this page drew without its stylesheet; this is the second. | No. | Part | What it does well | Fed on our site by | |---|---|---|---| | 1 | The state now, in the header | "KEINE UNWETTERWARNUNG" (no severe-weather warning) sits in the top bar beside the temperature of the reader's place, on every page. | `data/`weather/warnings.json (Lisbon's highest level in force, in IPMA's words) | | 2 | Last updated, and it refreshes itself | "Letzte Aktualisierung: Mi, 11. Nov, 03:39 Uhr" above the map, with a ticked box "Autom. Aktualisierung". | `data/`weather/warnings.json (read_utc, next_read_utc) | | 3 | A place first | One search box above the map ("Bitte Ort eingeben"): the warning text is shown for the place typed or the area clicked. | not ours yet: one district only (Lisbon) | | 4 | The map, municipality by municipality | Green where there is no warning, yellow for level 1: the areas are municipalities, far smaller than districts, with the main cities named. | our own redraw from IPMA's JSON; IPMA warns by district | | 5 | Kinds of hazard as buttons | A column of icon buttons beside the map, ending in "alle" (all), redraws it for one kind of hazard; two more below for the coast. | `data/`weather/warnings.json (type) | | 6 | The levels in words, and a step before a warning | Four levels named and numbered (Stufe 1 to 4, "Wetterwarnungen" to "Warnungen vor extremem Unwetter"), "Keine Warnungen" as its own colour, and a hatched "Vorabinformation Unwetter": advance information before a warning is issued. | IPMA's own description of its four levels, quoted and linked | | 7 | The situation, written and timed | "Beschreibung der Warnlage Deutschland", issued Wednesday 11.11.2026, 04:01 local time: two sentences (ice, fog, light frost), signed by the forecasting centre in Offenbach. | `data/`weather/communiques.json (number, validity, subject) | May the screenshot be shown: The map prints "Copyright: © Deutscher Wetterdienst".
