Nothing new observed today, but visibility was very limited.
Only a few cm's had fallen by the time forecasters left the field Sunday at midday, but it was snowing hard. The bond at this new interface so far appears good, but wind slab formation was observed in open areas at Treeline. These slabs were already up to 20cm thick and some cracking was observed. Monday could see 15 to 25cm more snow with strong NW winds. If this comes true, expect to find widespread wind slabs through the terrain.
