Avalanche Advisory
Advisory: Provo Area Mountains Issued by Evelyn Lees for Friday - November 20, 2015 - 7:24am
bottom line

The avalanche danger is MODERATE today for triggering a wind drift, which then has the potential to step down to the ground. Avoid any steep slope with rounded, dense or hard wind drifts. These dangerous drifts will be most widespread on upper elevation slopes, especially those facing northerly through easterly.

Any slide you trigger could eventually break to the ground, resulting in a nasty, rough ride, as you get dragged through rocks and trees.
special announcement

Most ski areas are closed to uphill traffic as they open or prepare to open. Check with each resort for their current uphill policies.
current conditions

Temperatures actually warmed overnight, into the upper twenties to mid 30s, keeping the rain/snow line above about 7,500’. Snow totals north of I-80 have been about a foot in the Logan area mountains, with 4 to 6 inches of very dense snow falling at the higher elevations of the Ogden area mountains. South of I-80, snow so far has been limited to 1 to 3 inches of equally dense snow.

With the cold front finally pushing through northern Utah, temperatures are starting to drop, and the winds have shifted to the northwest and increased. Speeds of 15 to 25 mph, with gusts to 40 mph are common. The highest peaks are gusting in the 50s.

The snow pack is still very shallow in the Provo area mountains, with only about a foot of snow a 8,000'. Packed roads and grassy slopes the best options for avoiding rocks and deadfall.
recent activity

No new avalanche activity reported from the backcountry, though there were not many observations.

Today, there will be another round of wind drifts to identify and avoid, as the dense new snow is good slab building material. The wind direction has varied, and the drifts will be most widespread on upper elevation slopes facing northeast through southeast. But watch for drifts cross-loaded onto other aspects, around terrain features like rock bands and gully walls, and on mid elevation slopes.

Cracking of the snow, especially long, shooting cracks, are an indications you’re in wind-drifted terrain and need to stay on low angle slopes. Avoid travel on any steep slope with new or old wind drifts.

Our weakest snow is on the ground – sugary grains of loose, faceted snow. This weak snow will become more sensitive and easier to trigger anywhere it is loaded with new wind drifts. Any collapsing or whomphing noises are red flags that you are in an area where you could trigger a slide – on slope or even from a distance. This means back off the steep slopes and stay on gentle, low angle terrain. A slide triggered on this layer will break to the ground, and even a short ride will be a rough and rocky.
weather

The cold front is through the Salt Lake area mountains and dropping south. Behind the front, temperatures are falling a few degrees and the winds have shifted to the northwest and increased. Winds speeds along the high ridgelines could average in the 40s with gusts to 60 mph into the afternoon, before decreasing this evening. In the mid elevation terrain, expect speeds of 15 to 20 mph, with gusts to 40. The mountains south of I-80 could pick up a few more inches of snow this morning, but the storm is rapidly scooting to the east. Dry, sunny warm weather is expected through the weekend, with the next chance for snow midweek as a slow moving storm moves through Utah.
