Kept by incident.ipma@web-summit.dinis, 11 November 2026, 11:50 UTC. At Dinis Cruz's word (BRIEF.md, 11 November, ~02:10 UTC): "start a new agent for IPMA and build a complete new visualisation, a section, a data analysis ... every JSON under api.ipma.pt/open-data, the cities, the ocean".
Not a warning service. Everything here is IPMA's, shown as IPMA's, with the time we read it; we add no forecast and no advice. Follow IPMA and ANEPC.

What this is. IPMA (Instituto Português do Mar e da Atmosfera) publishes warnings, forecasts, observations, the sea state, earthquakes and climate series as open files at api.ipma.pt. This section maps every one of them, reads them about once an hour (one request every few seconds, read-only), keeps the sha256 and the time of each read in git and the full responses in a data store, records what changed between reads, and draws views from them. The map above is drawn from IPMA's coordinates only: no tiles, no image.
Everything on this page is a fact in this site's sense: read from the body that warns (IPMA), with the file and the UTC time we read it. Where a figure is computed by us (a 24-hour sum, the nearest station), the page and the data say so.
Read 2026-11-11 11:47 UTC (IPMA's file dated 2026-11-11 11:15 UTC): 51 warnings above green across 22 of 25 areas; 9 red, 25 orange, 17 yellow. All of them, over time.
