Logan

Heightened avalanche conditions and MODERATE danger exist in drifted upper-elevation terrain where people could trigger slab avalanches of wind-drifted snow on slopes steeper than 30°. The snow is generally stable elsewhere, and the avalanche danger is LOW on most slopes in the backcountry.

Evaluate snow and terrain carefully and practice safe travel protocols by only exposing one person at a time to avalanche risk.

• There were no recent avalanches reported locally. Read about all avalanches and observations in the Logan Zone HERE.

It's quite a bit warmer this morning compared to yesterday, but the winds increased. Be prepared for frigid temperatures again today. It's 1° F at the summit of Paris Peak this morning, and 40 mph winds are making a -28° F wind chill! Plan for complications due to the cold; bring extra layers, warm drinks, and a fire starter in case of an emergency. Keep an eye on your partners, as frostbite and hypothermia are significant concerns.

Wicked wnds from the west picked up significantly yesterday afternoon and evening, and they continued overnight. With plenty of light snow from the weekend available for transport, our primary avalanche concern today is that people could trigger wind slab avalanches at upper elevations and on steep drifted slopes. Wind slab avalanches, 1 to 2 feet thick, are most likely on the lee side of major ridgelines and in and around terrain features, where winds deposited stiff drifts. Some wind slabs formed on preexisting weak surface snow and might be quite sensitive and easy to trigger.

Isolated deep slab avalanches, breaking 2 to 4 feet deep on a persistent weak layer near the ground, are unlikely, yet the consequences could be severe. 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. Be cautious of rocky, windswept slopes at upper elevation, and areas with generally shallow snow cover, around 3 feet deep or less, are the most suspect.

-The 8400' Tony Grove Snotel reports 5° F, with 58 inches of total snow (96% of normal SWE for the date).

-At the CSI weather station at 9700 feet on Logan Peak, winds are blowing from the west this morning at 36 mph with gusts of 46 mph, and it's 2° F,with a windchill of -25° F.

At our Card Canyon station, it's 0° F at 8800 feet, and there is 45 inches of total snow.

-On Paris Peak at 9500 feet, it is 0° F and the winds are blowing from the west-southwest at 38 mph with gusts of 43 mph. The windchill is -28° F.

Here's the NWS piont forecast for the Naomi Peak Area: Today: Sunny, with a high near 16. Wind chill values as low as -19. Breezy, with a west wind 16 to 23 mph, with gusts as high as 36 mph. Tonight: Mostly clear, with a low around 5. Wind chill values as low as -14. Breezy, with a west wind 20 to 26 mph, with gusts as high as 39 mph. Wednesday: Sunny, with a high near 17. Wind chill values as low as -14. Blustery, with a northwest wind 16 to 22 mph, with gusts as high as 33 mph.

Cold temperatures and wicked wind are the headlines for the next couple of days before a gradual warmup toward the end of the week. Once again, snow is likely in the Bear River Range over the weekend, perhaps starting on Friday afternoon and continuing through Saturday.

Matt made it up to the Garden City Bowls yesterday, and his observation is HERE. The extreme temperature gradient in the upper layers of his snowpit indicates potential rapid near-surface facet development. (The development of a probable persistent weak layer)

Strong winds scoured the snow off of windward slopes and deposited it as stiff wind slabs where they decelerated.
