I just talked to my buddy - he was in the snowstorm that hit Grayson Highlands/Mount Rogers last weekend - bailed a day early (worried the roads might be impassable if he waited) - he took his three-season Hubba HP and said he had absolutely no problem with it. The snow started the first day, never stopped until he left two days later, when it was knee deep, so I think he had to deal with snow load. The tent walls are pretty steep, which may have helped keep it from building up too badly. Of course, MSR just discontinued offering the HP series in the US>
