In sintesi

MODERATE avalanche danger exists on mid and upper-elevation slopes facing W-N-E where it is possible to trigger avalanches more than a foot deep failing on a buried persistent weak layer (PWL). A winter storm with snow and strong winds from the S will continue to load these slopes throughout the day, making it most likely to trigger a slide on slopes exposed to the wind. LOW danger exists on most other slopes.

The Utah Avalanche Center extended our Avalanche Watch as the storm continues to raise avalanche danger through the day and this evening.

Wind-drifted snow: Any new snow falling today will come with wind in the Ogden zone. Winds will stay at consistent loading speeds today, continuing to build deeper and more sensitive slabs throughout the day if(as) more snow falls.

You will be able to find wind slabs more than a foot deep near ridgelines and on exposed mid-elevation slopes facing W-N-E. Be on the lookout for drifts, dunes, pillows, and wind-textured surfaces as these are signs the wind has been at work. These will have the potential to break/propagated wider than expected, and possibly be triggered from a distance (remote triggering) as they may be built atop the weak snow that developed during our dry period in January...more on that below.

Our last significant snowfall was on January 9—more than a month ago. The snowpack weakened, or faceted, significantly since, with close to 2 feet of weak snow in some locations. The Dry January Layer (DJL), as you named it through our poll, can be found on upper and mid-elevation W-N-E facing slope. The DJL had 2-5 inches of low-density snow atop it from last week's storms, but it wasn't causing too many slides (yet) due to the lack of a slab.

Now, the series of storms that started last night are certain to build hefty slabs on top of the very weak DJL, with forecast snow totals reaching into 3 feet by late this week. This strong over weak structure will be likely to produce avalanches big enough to bury a person. As the storms carry on into the day and week, expect these to increase in size and likelihood.

These will become more sensitive the larger the slab builds atop them, meaning wind-loaded slopes mentioned above are most suspect. Expect these to be able to propagate widely, and potentially be triggered from a distance away (remote-triggering).

Recent Activity

Paige and I got to get out with Corey Kruse of Snowbasin yesterday.

Two reports from Saturday include:

- Josh Martineau on Bountiful Peak

- Derek DeBruin on Cutler Ridge

Both Josh and Derek reported a poor snowpack structure of faceted snow.

Special Announcement

Avalanche Watch vs. Warning: The UAC issued our first Avalanche WATCH of the season yesterday and extended it through tomorrow morning. We issue WATCHs when we believe the criteria for an Avalanche WARNING—the most severe avalanche alert product we have—may be met in the next 24-48 hours. More info on each of these from Bruce Tremper and Drew Hardesty HERE.

Bear River Lodge "Stay and Play Avalanche Course": March 19th-22nd in the Uintas. This course is designed for snowmobilers by snowmobilers, where you will learn avalanche rescue, riding skills, and how to survive in the backcountry. Come enjoy all the luxury offerings at Bear River Lodge and improve your skills along the way. Details and sign up HERE.

Snow and Weather

Last night, the first in a series of storms arrived on SW flow, which mostly meant wind for the Ogden zone. Temps dropped from the high 20s F to mid teens F overnight. Winds ripped out of the SW across the highest ridgelines in the 30-40s mph, gusting into the 680s at the top of Strawberry. The front of this first storm moved through quicker than expected.

This morning, mountain temps are in the low to mid teens F, and moderate to strong SW winds continue. Not much snow has fallen on the Ogden Skyline, with Powder Mountain reporting an anger inch as of 0700.

Today into tonight, a series of small storms will bring some light snow showers. These will favor the mountains East of Eden, and largely leave the Ogden Skyline feeling left out. SW winds will decrease throughout the day to 20-30s mph, and temps will be in the mid to high teens F. We can expect the following:

Less-favored areas (Ogden Skyline): Trace-1" snow and up to 0.1" H2O by 5 pm tonight
More-favored areas (Pow Mow, Monte Cristo): 2-5" snow and 0.2-0.4" H2O by 5 pm

Looking ahead, the cold front moves in tonight into early tomorrow morning. We can expect a shift to NW flow for tomorrow into Thursday.
