This morning, ridge top temperatures have clawed their way up to a mighty 10 degrees from the zero-or-below temperatures of the past few days. Ridge top winds remain light from the northeast. With these calm, clear conditions, there is a strong temperature inversion in the mountain valleys and the temperature down low is around zero this morning but should warm up fast when the sun comes out. There’s still lots of great 4-day-old powder on the wind and sun sheltered slopes with tricky wind drifts in most above-tree line slopes.
The reports of human triggered avalanches continue to diminish each day as the buried weak layer slowly gains strength. Yesterday, we heard about only one—a skier triggered avalanche on the Maybird-Red Pine ridge in Little Cottonwood Canyon. It was north facing, near tree line in a wind drifted area 1 ½ feet deep and 60 feet wide. No one was caught.
been four days now, since it quit snowing and snow collapses much less often as
you travel across it. O
Bottom Line: There is a MODERATE danger on any slope steeper than about 35 degrees, especially northwest through east facing slopes, that has not recently slid. This means that there are localized areas where you can still trigger an avalanche. There’s also a MODERATE danger on any steep slope with recent deposits of wind drifted snow.
Until Sunday, we’ll have enticingly delightful weather in the mountains and smog in the valleys with slowly warming ridge top temperatures and nearly no wind. Today should be clear with ridge top temperatures near 15 degrees and light winds from the northeast. 8,000’ temperatures around will rise to 25 degrees. By Friday afternoon, ridge top temperatures will warm to the mid 20’s and we’ll have a few high clouds on Friday but otherwise nice. For the extended forecast we have several nice-looking storms lined up starting Sunday and going through much of the week.
