Whumpfing, new snow and ridgetop winds

Beautiful snowy day, mostly calm except on ridgetops, with SW winds. I opened the uptrack past the knolls and up the Dome and experienced whumpfings the whole way (the biggest of them in the alpine, on the Dome), both on steeper and mellow slopes and on almost every steps I did. The group that followed behind me didn't noticed anything. I did open the uptrack towards Pollywood too from Fay-zurs and experienced whumpfings again while crossing the more open slopes. Sluff was fast on steeper aspects while riding down, but I didn't notice any cracking.
