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 Jamestown, Saint Helena 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.
