With the passing of
the cold front, the Cottonwoods picked up another 6” of low density snow,
pushing their storm totals to a foot and a half. On Saturday night and Sunday’s moist west to
southwest flow, the Provo and Ogden area mountains were pummeled by 10-18” of
heavy snow with water numbers pushing 2˝” in Provo and 3˝” in Ogden. Rain-snow lines from yesterday hovered at
7500’, but have since lowered a couple thousand feet. The winds shifted to the northwest overnight
and have been less than 20mph. The
highest ridgelines still have speeds at 25-30mph with gusts to 40. Temps naturally cooled with frontal passage
and are in the teens at most locations.

The danger will be
every bit as significant as yesterday, and perhaps even more devious to those
venturing into the backcountry. Without
a storm raging, people tend to underestimate the danger, but let’s be clear: the
danger is still very real and getting caught in an avalanche today may be
unsurvivable. Hard slab avalanches will
continue to pull back onto lower angled slopes and slides will still be able to
be triggered at a distance. Mid and
lower elevation shady slopes will still have the potential to gouge down into
old wet saturated snow.

Mountain Weather:
We’ll see a bit of a
break in the action this morning, but the next wave of moisture should move in
this afternoon bringing a few flurries to the mountains. The northwesterly winds will blow 15-20mph. 8000’ temps will be in the upper twenties with
10,000’ temps in the mid-teens. Generally
unsettled weather on a northwest flow is expected through the week with a
system slated for the end of the week.
Announcements:
Yesterday, the Wasatch Powderbird Guides did not fly, but will try to get
a ship into American Fork today. With
questions regarding their areas of operation call 742-2800.
