Kept by incident.social@web-summit.dinis, 11 November 2026, 11:51 UTC. At Dinis Cruz's word (BRIEF.md, 11 November, ~02:10 UTC): "on Bluesky, this is really cool, I like that we can capture that and actually get data. So let's create a whole Bluesky bit". Last read of the accounts: 11 Nov, 11:49 UTC.
Everything here is evidence: an account's own words, read at the address given, at the time given. A post by an outlet or a volunteers' association about a warning is a report or a relay, never the warning: the fact is on the body's own channel. Where we compare two times it is our analysis and says so. Not a warning service: follow IPMA and ANEPC.
not_on_bluesky: where we looked). Their own sites are their channels.s-1110T1909); at our read (11 Nov, 11:47 UTC) the account had posted nothing since: 14 posts since 8 November, none on the weather, Wednesday or Thursday.s-1111T0015). Lusa, the news agency, posted Web Summit's cancellation 53 minutes after the organisers' page.Analysis (ours): the time in the first column is the body's own (the timeline row's, or the time IPMA sent the message); the post is the earliest one by a listed account that we tied to the row (links.json).

Posts by anyone that match a search, since 8 November: how many, from how many accounts, the busiest hour, the languages the posts declare. No post, text, handle or address of these is kept: conversation.json holds numbers per hour and nothing else. The searches overlap and are not added up. A "+" means capped.

Read the same way (mastodon.json, read 11 Nov, 11:51 UTC; the reader: tools/social-mastodon.mjs). No body that decides or warns here has an account we could find, and neither has Web Summit: IPMA, ANEPC (civil protection), Web Summit, the Câmara de Lisboa, VOST Portugal, AEMET, Met Office, Météo-France, Copernicus, MeteoAlarm, Euronews. The organisations' accounts that exist are dormant or unverified:
| Account | Who | What shows it is theirs | Posts in all | Last post (day) |
|---|---|---|---|---|
eumetsat@mastodon.social | EUMETSAT (as the account names itself) | nothing verified | 48 | 2026-11-09 |
ECMWF@fediscience.org | ECMWF (as the account names itself) | nothing verified | 6 | 2024-02-06 |
Publico@masto.pt | Público (as the account names itself) | nothing verified | 41 | 2022-12-29 |
Lusa@masto.pt | Lusa (as the account names itself) | nothing verified | 8 | 2022-12-22 |
So there is nothing official to put on the time axis from Mastodon. The public conversation under the storm's tags, as counts only (each server sees only what reached it):

Not readable without logging in: the organisers' and the authorities' profiles answer with an empty page to a client that is not logged in (incident.researcher@'s read, data/decisions/sources.json, platforms_without_login). We do not log in and we keep nothing from it. If a body's post on X matters, it is cited from where the body or the press quotes it.
Each with the reason it counts as official or public-role, and who decided: accounts.json. Each handle opens that account's page. "Kept" is what we store: every post for the organisers, the posts about the storm for the others (matched by words: a few are about other weather, and say so by their text).

Left out, for the conductor to decide (nothing of theirs is stored): camaralisboa.bsky.social (not verified, not on the Câmara's domain, no posts: nothing shows it is the Câmara's); perturbacoes.pt (says itself that it is unofficial; who runs it is not stated: it could be a private person's); vostspain.bsky.social (not verified, not on its own domain; Spain is outside this incident's core); named journalists and meteorologists posting as such (a public role is a judgement per person: none is added without incident.conductor@'s yes. In round 1 their posts are inside the counts only.).
What we call (Bluesky's public API, no account, no login, one request every 3 seconds, a client named storm-charles-social-reader):
| Call | For | What we keep from the answer |
|---|---|---|
public.api.bsky.app/xrpc/app.bsky.actor.getProfile?actor=<handle> | each listed account: does it exist, is it verified | name, verification, follower and post counts |
public.api.bsky.app/xrpc/app.bsky.feed.getAuthorFeed?actor=<handle>&limit=100&filter=posts_no_replies | each listed account's own posts, back to 8 November (6 pages at most) | per post: time posted, time read, address, text (press: 200 characters), links, hashtags, what media it carries (not the media), counters, Bluesky's content id |
api.bsky.app/xrpc/app.bsky.feed.searchPosts?q=<search>&sort=latest&since=…&until=… | the public conversation | numbers only: posts per hour, per language, how many distinct accounts |
What is public: every post read here is public on Bluesky to anyone without an account; so are the handles, the counters and the content ids. The search answers only its first page without a login, so we walk back in time by asking again with until set to the oldest post of the page before.
What we refuse to keep:
What a card shows: who (and why the account counts), the time posted, the text, the timeline row it bears on and how, when we read it, the counters at that read, the content id, our record, and last the address on Bluesky, marked as leaving this site. Screenshots of the official posts are incident.archivist@'s (asked: the list is in capture-asks.json); when captured, the card will show our capture first.
The files: accounts.json (the list, the reasons, where we looked and found nothing, who was left out), posts.json (the index; posts/ holds one file per day: 2026-11-08, 2026-11-09, 2026-11-10, 2026-11-11), links.json (post to timeline row), offers.json (24 things the timeline lacks, offered to the conductor), conversation.json (the counts).
