current conditions

Today's advisory written by Kory Davis.

It is warm again today with mid elevation (7,000-8,000 ft) weather stations reporting in the 40s and upper elevation stations reporting in the 30s. One outlier is the Ben Lomond Peak weather station at 8,000 ft is reporting 41 degrees. I do not think that a strong refreeze of the upper snowpack occurred last night. This could cause wet activity earlier in the day than expected. Some good news is that it was cooler last night than Thursday night and temperatures today will be a touch cooler than yesterday with Highs in the low 40s at upper elevations.

Winds Last night were calm, Ridge winds were in the teens with gusts in the twenties.

With a potential quick shot of snow on Sunday night get familiar with our current snow surface on East-North-Northwest aspects because todays snow surface could be tomorrows problem. This might only be 1-2 inches of new snow but with a little wind we could see deeper wind slabs on Monday and Tuesday.

recent activity

Small Wet Loose activity was noted in the Ogden Mountains but was limited to Southeast -Southwest Steep aspects. There was some collapsing reported on South aspects by the Ski Areas.

Once again, Solar Aspects will see wet activity this could be earlier than usual with a poor refreeze again last night. The danger could rise to considerable with daytime heating. Damp snow was reported as early as 11a.m. yesterday. Look for obvious signs of instability on solar aspects. Keep it simple quick pole drag tests and visual observations are key on sunny days. Today you can chase the shade around the compass.

Poor refreezes at a number of mid-elevation weather stations begs the question of wet slab potential. Collapsing and unsupportable snow - along with free water in the snowpack - are red flags for today.

In the Ogden Mountains we have not seen any Persistent Deep Slab avalanches since Christmas, this does not mean they are gone, maybe just lurking waiting for the next storm or trigger. These would be in very isolated places but the consequences could be large.

We do have a hand full of layers and crusts in the Ogden Mountains from buried graupel (approximately 70 cm down) on a slick bed surface, buried surface hoar (30cm Down) in isolated areas and a rain crust (15-20 cm down) that we have not tested with a load yet. Keep these in mind as we move forward and hopefully winter strikes back.

Cornice issues could be seen today. These not only could trigger avalanches below, but it is similar to tumbling down the slope with a school bus. Stay back give them room.

Wind Slabs on upper elevation slops have been inactive for a couple days now, you may be able to find small pockets of wind slabs but observers have had no luck getting them to move.

weather

Today we will see mostly cloudy conditions with highs in the 40s with winds in the single digits and gusts to the high teens. Tonight will be cloudy with a slight cool down before a quick shot of snow on Sunday night. Snow totals will be in the 1-2 inch realm with strong winds with frontal passage.
