Forecast for the Logan Area Mountains

Toby Weed
Issued by Toby Weed on
Friday morning, March 26, 2021
There is LOW avalanche danger in the backcountry today, conditions are safe on most slopes, and people will still find excellent shallow powder riding conditions in north facing terrain. As usual there are a few exceptions, and small human triggered avalanches of wind drifted snow or cornice falls are possible on some steep upper elevation slopes. Also, loose wet avalanches entraining moist storm snow could rapidly become an issue as high angled sun warms up the fresh powder from the last couple days.

Weather and Snow
It's 23°F this morning at the 8400' Tony Grove Snotel, and there is 71 inches of total snow with 78% of normal SWE. About 4" of new snow fell in the last 24 hours. It's 16°F and light northwest winds are blowing around 6 mph at the 9700' CSI Logan Peak weather station. People will find very nice shallow powder riding conditions in the backcountry again today, especially in shady or north facing terrain. The high angled spring sun will be out later today and it will heat up the snow, make it sticky and moist, and probably cause an elevated danger of loose wet avalanches that could entrain large piles of debris on sustained pitches.
We expect mostly sunny skies today, with high temperatures at 9000' around 30°F and moderate winds from the north-northwest. Looks like fair weather and warming daytime temperatures this weekend....

Recent Avalanches
A party reported triggering multiple long running sluffs of moist storm snow in Wood Camp on 3-23-2021.
When the sun popped out for a while on Wednesday morning, numerous predictable natural loose wet avalanches or sluffs of moist storm snow occurred on sunny slopes.
Natural sluffs were fairly widespread on sunny slopes near Tony Grove Lake on Wednesday.

Avalanche Problem #1
Normal Caution
Type
Location
Likelihood
Size
Description
Avalanche problems are limited to newer snow and are found only in the very upper layers of the snowpack. Even so, it is wise to continue to use safe backcountry travel protocols and check be sure everyone in your party is transmitting and has a good probe and shovel. Go one person at a time and watch each other.
  1. Avalanches of recently drifted new snow up to about a foot deep are possible for people to trigger in steep upper elevation terrain.
  2. Large, overhanging ridge-top cornices have grown in recent days, and people might be fooled into getting too close to the edge. Warm temperatures this weekend could cause some of these to sag or even calve off. Cornice falls could cause avalanches on steep slopes below.
Avalanche Problem #2
Wet Snow
Type
Location
Likelihood
Size
Description
Natural sluffs or loose wet avalanches entraining a few inches of moistened fresh snow are quite possible in steep terrain later today as the sun warms up the fresh powder. These are quite predictable and generally manageable, but you really have to pay attention to the terrain you are in. Snow falling off rock bands or trees onto steep slopes or people venturing into steep terrain are the most likely triggers of loose wet avalanches today. Obviously, people want to avoid being hit by these avalanches from above, so be sure there are no other people above or below you and avoid being under steep slopes with potential for natural avalanches...
  • Watch out for trees, gullies, and other terrain traps below you if you venture into steep terrain... Even a small avalanche in the wrong place can hurt or kill you.
Additional Information
General Spring Travel Advise:
As daytime temperatures rise, softening the snow, the danger of wet avalanches will increase, so its a good idea to get in the habit of an early start and to plan on heading down before things get too sloppy.
-Watch for trees or other terrain traps below you if you venture onto steep slopes.
-If you start sinking deeply into wet snow, or if the snow you are traveling on becomes unsupportable due to the heat, it's time to leave.
Do you have the essential avalanche rescue gear (transceiver, probe, and shovel) and do you know how to use them? Watch this video to see how the three pieces of equipment work together. HERE
Please keep practicing with the Beacon Training Park at the Franklin Basin Trailhead. Test yourself and your riding partners. It is free, fun, and easy to use.
