We are taking the data for Europe from Meteoalarm and the info about avalanches is not there as well. It seems that the CapAlerts are not issued for avalanches in Switzerland. The avalanche warnings are only available on MeteoSwiss website. Not sure why their are not providing those information as CapAlert.
hmm,but on meteoalarm german warnings are available http://www.meteoalarm.eu/de_GE/0/0/DE-Deutschland.html
..but not on windy?
