Taiwan uses a county-by-county system for declaring work and class suspensions during typhoons and severe weather events. Here's what you need to know:
- Who decides: Each county/city mayor decides independently, based on Central Weather Administration forecasts and local conditions. There is no nationwide declaration.
- Announcement windows: Full-day or morning closures are announced the evening before (19:00–22:00). Supplemental morning announcements by 04:30. Afternoon/evening closures by 10:30.
- Reference thresholds: Sustained wind ≥7 Beaufort, gusts ≥10, 24hr rainfall ≥350mm (lowland) or ≥200mm (mountain). These are reference values — mayors have discretion.
- Private companies: Not mandatory to follow government closure, but most do. Workers who cannot commute safely cannot be penalized.
