Example alerts

Historical advisories re-rendered in the current alert layout — from the busiest email the system produces down to the quietest, plus the no-exposure cyclone monitoring format. Exposure alerts come in two versions: the condensed email subscribers receive, and the full-detail page it links to (all maps and per-threshold exposure charts).

These pages exist to collect feedback on the format — open an issue or reply to any alert email. Figures are re-generated from the archived forecasts and may differ slightly from what was sent at the time.
