Avalanche Advisory
Advisory: Provo Area Mountains Issued by Bruce Tremper for Monday - February 23, 2015 - 6:56am
bottom line

Most terrain has a LOW avalanche danger today but there is a MODERATE avalanche danger for recent deposits of wind drifted snow on steep slopes and also a MODERATE danger of wet sluffs and slabs on steep slopes facing into the sun in the heat of the day.




special announcement

Join us for Vertfest 2015, a weekend of riding, mountaineering, and avalanche skills clinics and the Wasatch Powder Keg Ski Mountaineering race at Brighton Mar 7 & 8. This is a great way to boost your mountain skills with some inexpensive half-day clinics led by pros. There will be gear giveaway and live music. Details here.

current conditions

Yesterday was a full-on feeding frenzy with hoards of powder-starved folks out tracking up most of the popular slopes. It's amazing how two months of absence makes the heart grow fonder. The foot or less of new snow settled and stiffened a bit by later in the day and most of the slopes that face into the sun got sun crusted by late in the day. Temperatures remain cold this morning in the single digits. Even though ferocious canyon winds continue to blow at the canyon mouths, the wind in the mountains remains much more reasonable but still picked up overnight blowing up to 30, gusting to 40 on the exposed peaks from the east and southeast. It seems to be mostly a high elevation phenomenon and the mid and lower elevations remain much more calm. Skies are clear.


Yes, this is the backcountry. The new snow was well loved on Sunday. Cardiff Fork is pretty well tracked out. Bruce Tremper photo

recent activity

Although most slopes were tracked up without incident, there was a couple notable avalanches:

A lone skier triggered a small, wet avalanche on the south face of Superior late in the day, which knocked him off his feet and washed him over a couple cliffs in steep terrain. He was OK and was able to get himself down. He filed a great report HERE.

Also, a guide with WPG intentionally ski cut a wind slab in the Session Mountains yesterday. Report HERE.

The wind increased overnight and is blowing up to 30, gusting to 40 from the east and southeast in the high elevation, exposed terrain. So you can expect wind slabs in the upper elevation, wind exposed terrain. As always, avoid steep slopes with recent deposits of wind drifted snow, which will look smooth and rounded. Note: the low elevation, southerly-facing slopes are colored gray because it's mostly bare rocks.

With drier air today, I would expect less clouds and stronger sun effects on the steep slopes that face into the sun. Avoid steep slopes when they get damp or soggy in the heat of the day.

weather

Ferocious canyon winds continue to blow at low elevation canyon mouths from Salt Lake northwards, but the wind in the mountains is much more reasonable but still strong enough to create wind slab problems. The high elevation automated weather stations are showing wind 30, gusting to 40 from the east and southeast. Temperatures will remain cool with single digits this morning, rising to the mid 20's today, then back into the single digits again overnight. Skies should be mostly clear but we could get a few mountain clouds with the east winds.

For the extended forecast, we should see nice weather again on Tuesday and warming into the mid 30's. Then, we have a weak disturbance on Wednesday and this weekend it looks like a pulse of moisture coming into southern Utah from California that may make it into northern Utah. Stay tuned.
