Good afternoon. This is Bruce Tremper with the
Well, this is it. This is our last avalanche advisory for the season. I will put an end of season message out on Monday. Tell you the truth, it feels great to be pulling the plug on a season like this—one with so little snow yet a record-setting number of unintentional human triggered avalanches in the backcountry. I’ll have more statistics on Monday.
This season is ending with a

Although it probably won’t be much of a problem on Sunday, another concern is that for the past week, we have been noticing large collapses of the surface frozen crusts into wet and occasionally dry underlying layers. These collapses are just in the top inch or two of snow and so far they have not initiated any avalanches. We’re not sure what to make of them. We suspect that on steep slopes, they may slide, but so far they have just been collapsing and staying in place. They are quite rare around her and I have seen them only occasionally in the past. I’ve never had an avalanche release on me when they collapse into wet snow, but it sure is unnerving. Here’s a photo taken yesterday of one of these large collapses (CLICK HERE). Occasionally, we see what we call “corn slab” avalanches this time of year, where a wet avalanche occurs despite the fact that the surface snow is frozen hard and is supportable. They are quite rare, but they do happen. Anyway, this is probably a sign that the corn snow conditions are not entirely bombproof yet and you should use the usual caution.
For tonight and Sunday, the avalanche danger is generally LOW. With daytime heating, the danger may rise to MODERATE on steep slopes.
Looks like a partly cloudy day on Sunday with overnight lows at 8,000’ tonight near 25 and getting up to 45 on Sunday. At 11,000’ the overnight low tonight should be in the mid teens and get up to the low 40’s on Sunday. After that, we have another spring storm on about Monday and Tuesday, but actually, I really don’t care because we’re not forecasting any more. After that, I won’t be glued to the weather radio and the Internet like usual. I love it this time of year when I quit paying attention to the weather. I wake up in the morning and look outside and say, “Hey, look at that, it’s raining.”
To report backcountry snow and avalanche conditions, especially if you observe or trigger an avalanche, call (801) 524-5304 or 1-800-662-4140, or email to [email protected] or fax to 801-524-6301. The information in this advisory is from the U.S. Forest Service, which is solely responsible for its content. This advisory describes general avalanche conditions and local variations always occur.
I will put an end of season message out on Monday.
Thanks for calling!
