About
How AVY Base works
AVY Base is not another forecast provider. We collect open data from national warning services across Europe and present it in one consistent layout using the European Avalanche Warning Services (EAWS) danger scale and problem types.
What you see on each page
- Danger levels (1–5) and region ratings come directly from official bulletins — never invented or translated by AI.
- Forecast text (snowpack, stability, tendency) comes from the national provider when they publish in your language, or from an official multilingual feed (e.g. EUREGIO for Austria).
- Where no official translation exists, we use machine translation (OpenAI) from the provider's source language. Those pages show an "Automatic translation" notice.
- The site is available in English, French, and German. URLs use a language prefix:
/en/,/fr/,/de/.
Official data vs machine translation
The table below describes how each country is served in each language. This reflects our configuration — off-season fallbacks (e.g. EAWS archives) may occasionally use machine translation when the live official API is empty.
Official (native)Published by the national service in that language.
Official feedSeparate official file or API in that language (no AI).
Machine translatedOpenAI translation from the provider's source language. Always marked on the forecast page.

How often data updates
Bulletins are refreshed from official sources on a schedule (typically hourly in season). Translations are cached on disk — when bulletin text changes, only new or changed passages are sent for translation.
Always check the bulletin date on each page and verify conditions with the official national service before heading into avalanche terrain.
EAWS standards
Danger icons, problem types, and the 1–5 scale follow EAWS standards, so the layout matches what skiers see on national sites — in a single cross-border view.
