Daily Canadian weather-alert intelligence from ECCC's keyless MSC GeoMet weather-alerts API. Active alert features are deduplicated into episodes (one issuance covering many regions = one episode), scored with a documented severity formula (risk colour x impact x confidence x alert type, max 100), and rolled into a dense 13-province/territory panel carrying episode counts by risk band and alert type, top-episode bilingual names and verbatim summaries, a documented 0-100 alert_pressure_score min-maxed across provinces, pressure_rank and pressure_tier. Primary key: (as_of, province_code). Cadence: daily; as_of is the UTC fetch date. Caveats: alerts are ephemeral — the snapshot covers what is active at fetch time; scores are a relative within-day gauge, not a forecast. Sample use: order by pressure_rank for the provinces under the most alert pressure today.

Les titres et les descriptions proviennent des sources de données, en anglais.

Colonne	Type	Description
as_of	string	UTC date of the fetch. The snapshot covers alerts active at fetch time; identical input produces an identical content hash. (unit: date)
province_code	string	2-letter province/territory code (closed set of 13). Together with as_of it is the primary key. (unit: code)
province_name_en	string	Province/territory name (English).
province_name_fr	string	Province/territory name (French).
country_code	string	ISO alpha-3 country code (CAN for every row). (unit: ISO 3166-1 alpha-3)
has_active_alerts	integer	1 when the province has >= 1 alert episode active at fetch time, else 0. (unit: flag)
n_features	integer	Raw active alert-region features in the province (before episode dedupe). (unit: count)
n_episodes	integer	Deduplicated alert episodes: one issuance (alert_code + province + publication_datetime) covering any number of regions counts once. (unit: count)
episodes_red	integer	Episodes whose ECCC risk colour is red (most severe band). (unit: count)
episodes_orange	integer	Episodes with orange risk colour. (unit: count)
episodes_yellow	integer	Episodes with yellow risk colour. (unit: count)
episodes_grey	integer	Episodes with grey risk colour (lowest band). (unit: count)
n_warnings	integer	Episodes of alert_type warning. (unit: count)
n_watches	integer	Episodes of alert_type watch. (unit: count)
n_advisories	integer	Episodes of alert_type advisory. (unit: count)
n_statements	integer	Episodes of alert_type statement. (unit: count)
n_alert_names	integer	Distinct ECCC alert names active in the province. (unit: count)
max_severity_points	float	Highest per-episode severity_points in the province (0-100). (unit: points)
total_severity_points	float	Sum of per-episode severity_points in the province; the alert-pressure score is min-maxed from this. (unit: points)
alert_pressure_score	float	0-100 alert-pressure score, min-maxed across the 13 provinces from total_severity_points (0 on an all-quiet day). (unit: 0-100)
pressure_rank	integer	Competition rank of the province by total severity points (1 = most alert pressure). (unit: rank)
pressure_tier	string	Activity tier from the score: severe (>=75), active (>=50), elevated (>=25), calm.
top_episode_code	string	ECCC alert code of the province's top-scoring episode (empty when no active alerts). (unit: code)
top_episode_name_en	string	ECCC alert name of the top episode (English, verbatim).
top_episode_name_fr	string	ECCC alert name of the top episode (French, verbatim).
top_episode_risk_colour	string	Risk colour of the top episode (red/orange/yellow/grey).
top_episode_n_regions	integer	Alerted regions covered by the top episode. (unit: count)
top_episode_summary_en	string	Verbatim truncation of the top episode's English alert text (sentence-boundary cut, 280 chars; never paraphrased per the ECCC licence).
top_episode_summary_fr	string	Verbatim truncation of the top episode's French alert text (sentence-boundary cut, 280 chars; never paraphrased per the ECCC licence).
source_url	string	Canonical ECCC MSC GeoMet weather-alerts items endpoint. (unit: URL)
row_hash	string	Deterministic 16-hex sha1 over the row's content fields. (unit: hash)
