Weather Comments
Tale of two kinds with regard to the weather. This observation includes riding on the Park City Ridgeline on Sunday and overnight weather changes into Monday morning the 7th. Weather on Sunday was cold in the early am with rapidly rising temperatures.Winds were calm with no visible signs of Transport observed. Skies were mostly cloudy with rain coming in by 1700 on Sunday at 8000 feet and higher. Reports from Cardiff/BCC at 9500 stated that the snow that was falling by late afternoon resembled a snow/rain mix.

Snow Characteristics Comments
Riding on Sunday was excellent in 4 to 6 inches of light density snow that fell on at least 5 inches of high density snow from earlier in the latest event. This combination provided a very supportable base with great turning in the light density surface snow. Steep slopes were ridden without any signs of instabilities.

Red Flags Comments
Rain event still unknown on how high it went, yet temperatures and SWE from Collins on Monday morning indicated a potential for rain/snow mix even at 9600.

Normal Caution

Same
Problem #1 Comments
Normal early season hazards were the only concern with the riding on Sunday. The warm temperatures that preceded the storm, and the warm dense snow that fell initially (combined with the warm winds) appeared to help stabilize any previous weak layers within our newly formed snowpack.

Wet Snow
Trend
Increasing Danger
Problem #2 Comments
Wild card will be the potential for a buried newly formed Rain Crust once the temperatures drop (and we get the forecast for incoming heavy snowfall) over the new few days; and how widespread this possible issue may be distributed. In the meantime, any snow from the latest events that is experiencing rain fall may be suspect for Wet Snow Avalanche Problems. The good news here is, the riding in any of these potential Wet Zones is going to be terrible and easily avoidable due to the lack of cover and difficulty of travel. Terrain Traps in likely places at Mid Elevations could be an issue for the unsuspecting.
