Points saillants

Very warm temperatures in the mountains have elevated the avalanche danger to MODERATE, especially in sunny upper-elevation terrain. Loose avalanches entraining wet snow are possible on slopes steeper than 30 degrees.

Wet avalanches entraining saturated loose snow are possible in the heat of midday, especially in sunny terrain. We found that the excessive warmth at upper elevations made the soft, loose snow sticky even in the deep trees in north-facing terrain yesterday. The Tony Grove Snotel reported about 6 hours with temperatures near and above 50° F in the middle of the day yesterday. Overnight temperatures were in the upper thirties.

Rapidly warming temperatures and natural avalanches on similar slopes are red flags indicating potential for more wet avalanches.

If the snow becomes saturated or sticky, move to lower-angle terrain or a cooler aspect or elevation.

Rollerballs, pinwheels, and natural sluffs are all signs of unstable snow.

Natural wet avalanches are most likely on sunny slopes in very steep rocky terrain and under cliffs.

Recent Activity

We observed a sizable debris pile from a recent natural loose wet avalanche on Thursday in Upper Steam Mill Canyon.

Snow and Weather

Persistent fair and mild weather will continue in the mountains through the weekend. Skies will be mostly sunny again today with high temperatures at 8500 feet near 42°F. Light to moderate winds will blow from the southwest. Under a strong high-pressure system, we can expect a repeat of today's conditions tomorrow. Clouds will move in on Sunday night, and 1 to 3 inches of accumulation from a quick-hitting frontal passage is expected at upper elevations in the Logan Zone on Monday. A cool and unsettled weather pattern will continue for the remainder of the upcoming week, as a series of storm systems move through the Great Basin.

This morning, at the UAC Card Canyon weather station at 8700 feet, the temperature is 38°F, and there is 40 inches of total snow. The Tony Grove Snotel at 8400 feet reports 39°F and 52 inches of total snow. On the summit of Logan Peak (9700 feet), the wind is blowing 19 mph from the south. It's 35°F on Paris Peak at 9500 feet, and the wind is blowing lightly from the south.

Different kinds of weak layers have developed on and near the snow surface in the past couple of weeks, and these will lead to dangerous avalanche conditions when buried by inevitable future snows. After a few weeks with minimal snow accumulations, the snow is generally stable, but it's loose and sugary. The current warm temperatures are turning the soft recrystallized surface snow to mush, and natural and triggered loose wet avalanches are possible on steep slopes today. The snow cover is quite thin at lower elevations, with sunny slopes below about 7000 feet in elevation completely bare of snow.

Additional Info

All backcountry travel involves inherent risk...

Travel with a partner, and cross or ride slopes steeper than 30 degrees one at a time while the rest of your group watches from a safe spot.
Ensure that everyone in the group has avalanche rescue equipment (a transceiver, probe, and shovel) and knows how to use it.
