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
A national hazards map coloured by warning type with a legend ordered by priority; each point forecast page has a "hazardous weather conditions" box first, then current conditions, a 7-day strip, an hourly graph (temperature, wind and gusts, precipitation chance as stacked charts) and the forecast discussion, the forecaster's own reasoning in text.
Forms: maps, warnings, timeline-hourly, radar, satellite, api, feed.
What it does best
The forecast discussion: the reasoning and the uncertainty in the forecaster's words, timestamped, next to the numbers. And an open alerts API in a standard format (CAP).
What we take from it
Publish the reasoning beside the numbers, signed and timed; keep the hazards box above everything else on the page.
