Weather Comments
Skiff of snow overnight, with the winds sustained out of the WNW in the moderate range at mid elevations and strong in the upper elevations. Temperatures once again rose significantly into the low 40's at 9000 feet. A brief period of sun shine allowed the southerly facing terrain to get damp in the early afternoon hours.

Snow Characteristics Comments

Snow surface conditions above 9500 feet continue to take a beating with the strong winds and warm temperatures. Most reports state extremely variable riding with one good turn intermixed with several others of lessor qualities. Despite the above average temperatures, the snow surfaces on the upper half of the compass remained cold and dry once again. Sheltered terrain, mostly on northerly facing treed terrain has the only creamy thick/dense riding left.

Problem #1 Comments
<p>Field observations and snowpits found rounding and sintering going on in the basal facets in areas with HS 130 and greater. Along with this, the basal facets appeared to be becoming moist in all locations except pits above 10200 feet.</p> <p>&nbsp;</p>

Problem #2 Comments
<p>See above with regard to the strong winds and light transport, and as a result small pockets of isolated wind slabs may be found in the upper elevations predominantly on easterly facing aspects.&nbsp;</p> <p>Of note, overnight lows at 8000 feet and below appear to have not allowed for a refreeze&nbsp;for at least three days now as of Sunday morning the fourth. With the forecast for more of the same, and a chance of light rain below 7500 feet, Wet Slab potential appears possible. At this point, observations have been noting a saturated snowpack at these lower elevations. Travel in the lower elevations on or below steep terrain is not recommended.&nbsp;</p>
