Today may feel more like March kite flying weather than midwinter as a warm, southwesterly flow sets up ahead of the next storm system. Currently, under mostly clear skies, winds are from a westerly direction, in the 5 to 15 mph range. Temperatures are in the mid teens at 10,000 and the low 20s at 7 to 8,000. The areas of dense, settled powder are shrinking, but can still be found on sheltered, shady mid and upper elevation slopes. Elsewhere there is a sea of breakable crusts, with some wind damage on exposed ridges and slopes.
Yesterday, several more shallow winds slabs and sluffs were triggered on steep, shady slopes. The winds slabs averaged 6 to 12 deep, up to 40 wide, and were triggered along ridges and mid slope. They were substantial enough to be dangerous, and some were running faster than expected. This afternoon, this problem will become more widespread as a whole new batch of sensitive drifts form when the winds pick up. Cornices are becoming increasingly sensitive, breaking back further and much larger than expected, and should be given a wide berth.
The other major concern for today will be wet sluffs as the warmer temperatures combined with direct sun and thin clouds will heat up the surface snow. Both human triggered and spontaneous damp sluffs will be possible at the mid and lower elevations on all aspects, especially shady slopes, and on steep, sunny upper elevation slopes.
Line for the Wasatch Range, including the
The avalanche danger is MODERATE on slopes steeper than about 35 degrees with old or new drifts of wind blown snow. On other slopes, the avalanche danger is low this morning, but the danger of wet loose sluffs will rise to moderate on steep slopes with day time heating.

The Wasatch Powderbird Guides were in Cardiff and Days yesterday, and today they will have one ship in Mineral, Cardiff, Days, Silver, Porter, Alexander, Gobblers, Lambs and Grizzly Gulch drainages, with a second ship south in American Fork and Cascade Ridge.
