Similarly, it's gusting to only 33 mph on Cardiff Peak.
Now that's still a stiff wind and it's going to feel mighty cold on the ridges, but these are locations that can gust over 60 mph (Hidden Peak sometimes over 80), so we're not talking about winds that are unusually strong.
What is unique is that there is fresh, dry snow to transport and clear skies so we can see it happening. The Utah Avalanche Center reports the overnight snow had a 6-8% water content. Such snow is easily lofted by the wind. However, that lofting can only last for so long. The wind will eventually scour off all the easily transported snow and the snow plumes will become more localized and less widespread. Until then, enjoy the show.
