Good Morning. This is Bruce Tremper with the
It’s funny weather we get
this time of year. Yesterday, we had a blizzard
of apricot and apple blossoms along with uncounted tons of desert dust. Today we have a blizzard of some strange,
white substance we haven’t seen in town in quite some time. In the mountains we have 7-10 inches of fairly
light density snow, fairly evenly spread through most parts of the
Most likely we won’t have to worry about avalanches breaking into deeper layers of old snow because the very warm temperatures consolidated the snowpack, effectively raising the ground level in most areas. So today the main concern will be the new snow, which like a golden retriever dog, wears its emotions on the surface and there’s seldom any hidden agendas. Today you will almost certainly be able to get some loose sluffs going on the steep slopes that have old, hard crusts underneath and you might find some shallow, soft slab avalanches in places. Where the wind has deposited the new snow into drifts, you will be able to trigger some soft wind slabs about a foot deep and up to two feet deep in very wind exposed places. For the most part, these kinds of wind slabs will tend to break at your feet instead of above you, making for more user-friendly conditions as far as wind slabs go—that is if you know what you are doing. As more new snow piles up today, especially if the wind blows hard, the danger of triggering wind slabs will rise.
Bottom Line (SLC,
Today there is a MODERATE danger of loose snow sluffs and soft wind slabs on any slope around 35 degrees or steeper, meaning that there’s localized places where you can trigger an avalanche. If we get more than about a foot of snow combined with strong winds the avalanche danger may rise to CONSIDERABLE on steep slopes with recent wind drifts. Otherwise the danger is mostly LOW.
This morning we have one strong pulse of snow ending and another pulse coming in for about mid day. We should get another 3-7 inches of snow today before we get a break in the action tonight. Today ridge top winds should blow 15-25 from the west and northwest with 10,000’ temperatures getting mighty chilly, down around 10 degrees today and around 5 degrees tonight. At 8,000’ the high today should be near 25 with an overnight low near 12. Skies should be cloudy to partly cloudy all day. For the extended forecast, winter is certainly not over yet. We have another shot of snow on Friday and yet another pulse on Saturday and Sunday. Then we have a strong, warm ridge building in for the rest of the week with the possibility of another storm for late next weekend.
