Avalanche Advisory
Advisory: Provo Area Mountains Issued by Drew Hardesty for Tuesday - March 18, 2014 - 7:09am
bottom line

Pockets of MODERATE danger exist in the steep open wind drifted terrain and most pronounced along the north to east to south facing slopes. Human triggered avalanches are possible. Most other terrain has a generally Low avalanche danger. Collapsing and shooting cracks are key signs of instability.

Confidence level in today's advisory is "fair"...and I'd approach steep terrain with extra caution this morning. Safe and better snow conditions can be found in the mid elevation wind sheltered terrain of all aspects on slopes up to 30 degrees in steepness.




current conditions

Now that's a nice storm for the Wasatch - storm totals are about 12" in upper Little cottonwood, 6-9" in Big Cottonwood, Park City, and Ogden mountains, and about a trace or so in the Provo mountains.

Currently, skies are mostly cloudy. Winds are north to northwesterly at 15-20mph. Temps are in the single digits to low teens.

I suspect you'll find shallow pockets of wind slab in the open exposed bowls and alpine terrain today.

We often will say "Can be manageable or unmanageable avalanche conditions associated with higher levels of certainty for experienced snow travelers. Extra Caution is advised. Test slopes, ski cuts, previous tracks, and cornice drops may provide some level of information on stability."... and to some degree this depends on whether we're dealing with a soft slab or a hard slab. Remember, soft slabs you're "in", hard slabs you're "on'...and hard slabs will break above you.

Large cornices cap the high and mid-elevation ridgelines and may be triggered on approach. Like hard slabs, they often break back further than expected, sometimes "this side - the windward side" of the apex of the ridgeline. Cornices are dangerous - you'll need a spotter sometimes to determine where the true edge of the ridgeline is...AND NEVER DROP A CORNICE IF YOU CAN'T SEE DOWN THE SLOPE. A very good friend of mine doing a crown profile in Monte Cristo (see below) years ago had an unintentionally triggered box-car of a cornice hit him directly making for a very close call above radical terrain.

weather

We'll have mostly-becoming-partly cloudy skies today with some potential for instability showers over localized terrain. Winds will be from the north and northwest at 10-15mph; temps will be in the 15F at 10k and 20-22F range at 8000'. Clearing expected for tonight into tomorrow with a grazing system for Thursday and some unsettled weather for the weekend.
