Heat you can read. Every fire now shows how much heat the satellite measured, what that usually means (how big a fire it is, how much is burning, what the smoke may do) and whether it is stronger or weaker than at the same time yesterday, with the number of passes it rests on. When there are too few passes, it says so. A new outlook for the next 24 hours lists the wind, dry air, heat, dry fuel and slope behind each fire's spread potential, with every ingredient and its weight shown. It is an outlook, not a prediction. A For you card shows how far a fire is, in which direction, whether the wind is carrying its smoke toward you, a rough window for when smoke could arrive, the air quality, and plain steps for what to do and what not to do. It all runs on your device and your location is never sent anywhere. Alerts are quieter and more useful: new fires inside your radius, fires that get stronger, and fires near where you are. The same fire is not repeated within hours, nothing makes a sound at night, and there is a daily limit, except for real danger. A Today briefing now opens the Outlook tab. Permission prompts appear only when you use a feature that needs them. The Apple Watch app is now translated and shows the heat class, trend and what to do.
