Most weather apps answer a question you are not asking. The forecast at your destination does not tell you whether the pass will be under fog at seven in the morning, or whether that fire is on your road or six kilometres off it.
Tramontana reads the weather along your route, at the hour you actually arrive at each point, and marks active wildfires on the same line.
Conditions are drawn on the road itself. Severity runs from 1 to 5 and is shown three ways at once, as a number, a colour and a pattern, so it still reads with sun on the screen or if colours are hard to tell apart. A clear road is left unmarked, because colour is reserved for hazard.
Drag the time ruler and the whole route is read again for the new arrival times. Leaving two hours later can trade fog for a storm.
It is a bulletin, not an alarm. Fires are seen by satellites passing overhead a few times a day, so a detection is commonly several hours old. Every fire shows its own age. Tramontana never tells you whether to drive, and it is not an emergency service. If you are in danger, call 112.
