morning, this is Evelyn Lees with the
Under clear skies, temperatures are mostly in the teens this morning, with single digits at highest elevations and in the mountain valley bottoms. Winds are generally less than 10 miles per hour, from a northwesterly direction. Only the highest peaks have wind speeds of 15 to 25, with gusts into the 30’s. Turning and riding conditions are still very good on sheltered shady slopes in recrystalized powder, though many of the heavily tracked slopes remind you how close they are to Was Angeles.
Yesterday, there was a distinct increase in
avalanche activity. In the
My field work this week has found remarkable variation with in just a few miles in the central Wasatch. Some slopes have very strong snow, where steep lines can be skied and boarded safely. Other slopes have very weak snow, where I was unable to isolate a column in my snow pits. If you’re planning on hitting the steep slopes today, take the time dig down and assess the strength of both the January rain/rime crust and the near surface facets. It doesn’t take a back hoe, and it might just keep you out of trouble.
Sluffing of the surface snow will continue to be a problem at all elevations on very steep shady slopes. Also watch and avoid the few shallow wind drifts that may form along the highest ridges.
Line for the Wasatch Range, including the
The avalanche danger is moderate on northwest through easterly facing slopes, steeper than about 35 degrees. While there are only isolated areas where you could trigger slab avalanche, carefully evaluate any steep slope and remember that slides are being triggered from a distance from lower angle slopes. On slopes less steep than 35 degrees, the avalanche danger is generally low.
Another weak disturbance will move through the area late this afternoon and tonight, bringing a flurry or two. Clouds will increase later today, with 10,000’ highs in the mid teens and 8,000’ highs near 30. Winds will be from a northwesterly direction, in the 10 to 20 mph range, and may increase towards evening. More clouds and much warmer temperatures are in the forecast for Monday. The earliest chance for significant snow appears to be mid week.
