St. Anton almost never lacks snow. There will be decent pow conditions every year. The tricky part is you never know when. Last season, it started dumping in early December and hasn't really snowed a lot for the rest of the season. I unpacked my mountainbike in early Feb and toured the Alps.
This year, early December, I biked up to 3000m. Snow came after Christmas, meter after meter, resulting in one of the craziest pow conditions I have ever witnessed. I don't think it will melt until May.
