Logan

There is MODERATE avalanche danger, and human-triggered avalanches are possible in upper and mid-elevation terrain. The problem is most pronounced along ridgelines and around lee terrain features, and here, you could trigger sensitive slabs of wind-drifted new snow. Isolated deep slab avalanches, breaking 2 to 4 feet deep on a persistent weak layer, are unlikely, yet the consequences could be severe.

• Evaluate snow and terrain carefully and continue to practice safe travel protocols by only exposing one person at a time to avalanche risk.
• You'll find very good shallow powder riding conditions in shaded, sheltered terrain.
• Prepare for very cold temperatures for the next few days and adjust your travel plan accordingly.

• Read about all avalanches and observations in the Logan Zone HERE.
• Remember, the information you share about avalanches you see or trigger could save lives.

Avalanches of wind-drifted snow could be a foot or so deep, as only about 4-6 inches of low-density powder fell yesterday and overnight. The new snow will improve riding conditions, and I expect today's wind slabs to be isolated to prominent ridgelines and lee terrain features. The likelihood of triggering a persistent deep hard slab avalanche is very low, but we are still suspicious of slopes holding poor snowpack structure, mainly on the north half of the compass. Yesterday, we found very good, fast, settled powder riding conditions in shaded, sheltered, mid and high-elevation terrain where the snow surface has weakened and become faceted in the top 3-5 inches. Surface hoar, too, has developed in protected terrain, making for "loud" powder turning. *Be prepared for very cold temperatures today through Monday. Plan accordingly and have extra layers, warm drinks, and a fire starter, in case of an emergency.

-The 8400' Tony Grove Snotel reports 8° F, with 61 inches of total snow (102% of normal SWE for the date).

-Winds blowing from the northwest this morning at 9700 feet. At the CSI weather station on Logan Peak, the wind is blowing 15 mph with gusts of 25 mph, and it's 1° F.

At our Card Canyon station, it's 5° F at 8800 feet, and there is 48 inches of snow total.

-On Paris Peak at 9500 feet in Bloomington Canyon, it is -1° F, and the winds are blowing from the north-northeast at 13 to 17 mph. The windchill is -19° F. Brrrr. Today will eventually be mostly sunny but very cold in the mountains, with an expected high of 11° F at 8500'. Winds will blow from the north-northwest at 10-15 mph, making it feel even colder. A small disturbance will come through the zone on Sunday, bringing clouds and possibly a snow shower, but little accumulation is expected. The cold temperatures are the big story for at least the next few days before a gradual warmup begins toward the end of the week.
