Good to know

Radar, lightning and the airport reports are measured; temperature and wind come from a forecast model for the nearest hour, so a thermometer in Sierre can read differently.
Radar detail stops at about zoom 7 and lightning at zoom 8, so the weather of a single street isn’t resolved.
Use it to see conditions, not to make safety decisions; for those, follow your local weather service’s warnings.
