FAQ
Why is this page always active?
Alert pages are always indexed (always-live) even when the event is dormant. This avoids Google's indexing delay (2-7 days) that would make flip-flop pages useless during short events.
Where does the data come from?
Official alerts come from MeteoSwiss federal bulletin (alerts.meteoswiss.admin.ch). Current weather data comes from a council of three sources (Open-Meteo, Met.no, MeteoSwiss observation) for redundancy.
What should I do if the alert is active when I need to leave?
Check the relevant valico page (e.g. /tempi-attesa-frontiera/chiasso/) for road conditions and webcams. Consider recommended alternatives. Subscribe to the newsletter for email commute alerts.
