Good morning, this is Evelyn Lees with the
UDOT plans to conduct artillery control work in Little Cottonwood Canyon this morning, beginning at 10 am. Please stay clear of the avalanche paths on the north side of the canyon from Tanners to White Pine until after 10:30 am. For updates, call 801-975-4383.
Skies are mostly cloudy this morning, and temperatures have warmed into the mid 20s at 9,000. 24 hour snow totals south of I-80 are in the 1 to 3 range. Portions of the Ogden and Logan area mountains have received more, with up to .7 of water. The westerly winds have increased this morning into the 10 to 15 mph range, with gusts in the 20s. The highest peaks are averaging 25 to 35 mph, with gusts to 45.
Snowpack and Avalanche Conditions:
Throughout the range, all reports were of stable snow yesterday. With effort, you could trigger a small sluff on a steep slope, but the snow still refused to act as a cohesive slab, despite weakness within the new snow. Today, with another few inches of warm, dense snow in the forecast and slightly faster wind speeds, sensitive wind drifts may develop in upper elevation terrain, especially along the ridgelines. Watch for cracking of the snow around your boards, and use slope cuts on test slopes and cornice kicking to test if a slab is developing. If you missed these links yesterday, here are some great demos of the shovel tilt test, which also works well to reveal the weaknesses in the upper pack. (PHOTO) (Quicktime video, 5.3mb),
The creepy part of
backcountry travel these days is due to all the layers of sugary, faceted snow deeper
in the pack, most widespread outside the deeper snowpack of upper Little and Big Cottonwood Canyons. So far, the small, incremental loads of snow are
allowing these facets to adjust to the added weight. But at some point, the facets on an
individual slope will become overloaded.
There is potential for one of these deeper slides to occur in the
