High expectations for continued snowfall fizzled with the mountains only picking up a couple of inches today. Winds were blowing near 20mph out of the west until about noon when they abruptly dropped off to less than 10mph. Today’s temperatures dropped into the upper teens and low twenties as my beard froze for the first time of the season. Turning and riding and conditions are excellent at the upper elevations with a base near 5’. The mid-elevations and sunny aspects are good as well with 4-8” over a mostly supportable crust.
Today, the avalanche problems were isolated to some new 4-8” soft slabs on the lee of the upper ridgelines. Cornices are beginning to become large with some sensitive and breaking back farther than expected. The good news is that this isolated danger is quite manageable with slope-cutting and cornice dropping and by watching your slope angles. Much of the activity from yesterday was not as widespread today, with the trend continuing into tomorrow. For Saturday, little expected snowfall and light winds should do little to increase the avalanche potential, so the danger will be isolated to the rogue windslab at the highest elevations.
Remember, for the most part, the unopened ski areas are not doing control work, and are just as dangerous as the backcountry. Alta Ski Area will be open to uphill traffic on Saturday but may close for uphill traffic again depending on the next storm.
avalanche danger is LOW in most areas. Steep upper elevation slopes with recent
deposits of wind-drifted snow still have a MODERATE danger. Places like the south slope of the
A weak storm passing to the north of us should offer the central Wasatch another inch or two tonight and tomorrow with continued northwesterly winds in the 10-15mph range. The Logan and Idaho border areas should fare substantially better out of this shortwave, accumulating as much as 6-10” in the next 24 hours. Tomorrow’s highs at 8000’ will be in the mid-thirties with ridgetop temps in the low twenties. Northwesterly winds should be 15mph until picking up Saturday night ahead of the next storm, slated to affect the central Wasatch Saturday night through early Monday morning. At this stage, it looks like areas favored by a northwest flow may pick up as much as a foot and a half. Sunday’s cold front should bring us the coldest temps yet, as 10,000’ temps plummet to 12 degrees F.
