Overnight snowfall totals are 1-2" and winds are out of the northwest, gusting in the 20's Temperatures are in the low to mid teens and it is snowing lightly.
Since the storm began on Sunday, the Provo mountains have recorded 2' of snow and nearly 4" of water. Moderate to strong winds, mostly along ridgetops but occasionally getting into mid elevation terrain, have also added stress to the snowpack. These are significant loading events.
For today, light snowfall is forecasted with another 3-6" expected by sundown. Winds will be from the northwest, gusting into the 20's and low 30's along upper elevation ridgelines. Occasional periods of light to moderate snowfall can be expected throughout the day.
No avalanche activity was reported from the Provo mountains on Tuesday. In the Salt Lake mountains, a couple of significant natural avalanches occurred on Tuesday along the Park City ridgeline. These were on northeast aspects that were wind-loaded from the sustained period of strong southwest winds. These avalanches were likely triggered from natural cornice falls, and were on slopes that have previously avalanched this season (known as "repeaters"). These slides included Scott's Peak (observation
), but the attention-getter was South Monitor which had a crown up to 8' thick and ran over 1/4 mile wide. You can read Mark White's usual excellent writeup and photos on this observation

Although much less dramatic than what is shown above, yesterday my partner and I noted three different avalanches in Days Draw (observation
). These were failing on a density inversion within the storm snow. Slides similar to this may be possible in the Provo mountains today.
