Skitourenguru .ch is a fabulous resource that provides avalanche information based on a machine language model. Is is not perfect, but avalanche prediction will probably never be an exact science. In the meantime it provides ski touring enthusiasts in the Alps and Jura a huge amount of useful information.
The main focus is Switzerland, but the web site has become a go-to resource, with tens of thousands of active users and over 1000 ski tours covered from Switzerland alone.
Twice a day the site is updated with data from the authoritative SLF and uses daily avalanche forecasts from the past 19 years, covering over 5000 avalanche forecasts augmented with data on 1,800 severe avalanche accidents and 50,000km of GPS tracks from actual backcountry ski tours.
