In sintesi

After several days of elevated westerly winds, avalanche danger is MODERATE across all upper elevations and on mid-elevation slopes facing northwest through east. Watch for sensitive slabs of wind-drifted snow 6 to 12 inches deep.

The elevated winds and cooler temperatures should keep the snow surface cool enough, but if the sun does come out, there is potential for wet-snow avalanches on east, south, and west aspects, as well as low-elevation northerly slopes.

Winds from the west increased overnight and will remain elevated throughout the day, creating pockets of wind-drifted snow at upper elevations, including some exposed mid-elevation slopes. While these slabs are most prominent on leeward slopes, strong winds can load any aspect due to cross-loading from swirling and shifting wind directions.

The prolonged elevated winds will continue to form both soft and some hard slabs of wind-drifted snow. These fresh wind drifts may be sensitive and 6 to 12 inches deep, possibly deeper in upper-elevation alpine terrain. Where the snow is becoming more supportable, the slabs may allow travel further onto the slope before signs of cracking or instability appear.

The Dry January Layer (DJL) of faceted snow is 2-4 feet deep and buried by a strong slab and supportable crusts, with the last reported human-triggered avalanche failing on the DJL on February 26. As we continue to move further away from our last loading event, triggering an avalanche failing on the DJL is unlikely, and this problem is moving toward dormancy.

The suspect terrain where you can still trigger a deep, hard slab avalanche failing on the DJL will be on a northerly aspect at the upper elevations, where there is a thinner snowpack, such as a "repeater slope" that avalanched during our mid-February avalanche cycle.

Stairs Gulch avalanche – natural on the PWL, 3/6 – likely a repeater slope.

Although temperatures will be warm, the increased cloud cover and westerly winds should keep the snow surface cool today and limit avalanche activity involving wet-loose snow on solar and southerly aspects. If the sun does come out for a prolonged period, avalanche danger could rise to MODERATE on solar aspects and lower-elevation north-facing terrain.

Pay attention to changing conditions. Watch for wet rollerballs and soggy snow as signs that the snow surface is taking on heat, and switch to a different aspect.

Recent Activity

No new observations from the Salt Lake area backcountry yesterday. Ski resorts reported widespread roller balls and crusty snow.

On Sunday, an avalanche on a northwest aspect at 10,000 feet in Scottie’s Bowl was triggered by snowboarders. The avalanche was 18 inches deep and 25 feet wide, and the slope was likely wind-loaded.

Snow and Weather

This morning, skies are partly cloudy, and temperatures are in the upper 20s to mid 30s °F. Only a few select weather stations, primarily above 10,000 feet, dropped below freezing overnight. Winds are from the west, gusting 25 to 40 mph, with 11,000-foot gusts near 70 mph.

Today, expect partly to mostly cloudy skies with temperatures warming into the low 40s °F and a chance for a trace amount of precipitation early this afternoon. No real measurable snow is expected. Westerly winds will remain elevated throughout the day, gusting 25 to 35 mph along exposed mid and upper elevation ridges, with 11,000-foot gusts in the 60s mph.

After a brief cool down, temperatures will start warming again later this week. A weak system may brush the area this weekend, but it looks mostly dry with just a slight chance of a little snow and some increased west to northwest winds, followed by another stretch of warm, dry weather.

Although there was plenty of sun this weekend, temperatures stayed cool enough to preserve cold, dry snow on shaded northerly aspects.
