Common questions
- How high is Großer Arber?
- Großer Arber stands at approx. 1456 m. The height comes from OpenStreetMap, rounded to the metre, and is not measured by Mostly.
- Why is mountain weather different from the forecast in the valley?
- It is colder up there, windier, and often in different cloud. So Mostly forecasts several heights and shows temperature, apparent temperature, wind, gusts and the freezing level per level, instead of writing a valley value onto a summit.
- Does this replace the avalanche bulletin?
- No. Mostly shows the official bulletin for the region the summit lies in, with danger level and elevation band — written by the avalanche warning services. The judgement on the ground stays yours.
