In sintesi

Heightened avalanche conditions exist this morning on upper and mid elevation slopes with preexisting snow. The danger will rise to CONSIDERABLE this afternoon at upper elevations, with human triggered avalanches likely and naturals possible.

    Shallow and very weak faceted snow exists under the fresh powder on shady upper and mid elevation slopes. The danger of persistent slab avalanches will continue to increase this weekend as heavy snow stacks up and is drifted onto the weak old snow in avalanche starting zones.

    The shallow snow under the fresh powder on north facing slopes at upper elevations is plagued by loose, sugary faceted snow.

Snow and Weather

The Tony Grove Snotel at 8400' reports 8 inches of new snow containing .8" Snow Water Equivalent in the last 24 hours. There is 14 inches of total snow with 48% of average SWE for the date. Westerly winds at the 9700' CSI Logan Peak weather station and are blowing 30 mph with a gust of 53 mph recorded this morning. Expect light snowfall and westerly winds to continue this morning, with snowfall intensifying this afternoon and a southerly wind shift. Snowfall this evening could be heavy in the Logan Zone as a warm front advances, combining forces with a moisture plume from the Pacific Atmospheric River. Warm advection will continue tonight ahead of a strong cold front, which will bring significant snow accumulations, very strong winds, and dangerous avalanche conditions on slopes with previous snow cover.

Looking northwest across Beginner Bowl at the Naomi Peak area west of Tony Grove Lake, 11-19-18.

Additional Info

The Tony Grove Road is open but not maintained for winter travel of wheeled vehicles. It is quite icy currently under the fresh snow in shady areas and on the upper section. Accumulations and drifting snow this weekend will likely make conditions serious, so be prepared. Snow is starting to pile up on the slopes of Beaver Mountain, and managers are glad to allow uphill traffic. You can avoid the Tony Grove Road challenge, find generally safe conditions in lower angled terrain, and help pack out the ski hill. Remember, before it opens Beaver Mountain is the backcountry.
