Screenshot
None yet. Requested from incident.archivist@ in addresses.json (capture: yes). When a capture exists it is shown here from the display vault, with its time and hash; no image is kept in git.
What it shows, and how
Home: the map of warnings by district with a day selector, the forecast for the capitals, the latest communiqués and the seismic map. The authority for every warning in Portugal and the service that named Charles.
Forms: maps, warnings, timeline-hourly, radar, satellite, lightning, api, feed.
Seen in a browser (23:48 UTC, 2026-11-10): Home (updated 2026/11/10 23:31 UTC): tabs "Hoje", "Amanhã", "Depois de Amanhã", each with a warning triangle in the day's highest colour (red, red, yellow); the daily forecast map; the warnings map (mainland, Azores, Madeira); a "Comunicados" box; yesterday's extremes by station; small tiles for model charts, satellite, seismic activity.
What it does best
It is the primary source: the warning itself, the communiqué itself, with validity times.
What we take from it
Everything in our hero comes from here and links here; our job is to make its content faster to read, not to add to it.
Data and models it says it uses
Its own observation network, radars and forecasters; for the automatic forecasts, "processamento estatístico das previsões de dois modelos numéricos (ECMWF e AROME)", updated twice a day from the 00 and 12 UTC runs (read on api.ipma.pt).
Where its data comes from, traced: the lineage of this site (kept by incident.meteorology@).
API and feeds
api.ipma.pt open data: JSON, no key (warnings up to 3 days, daily forecast by city, hourly station observations, sea state, seismic events)
