Provo Avalanche Advisory

Forecaster: Drew Hardesty

BOTTOM LINE

Danger by aspect and elevation on slopes approaching 35° or steeper.

Danger Rose Tutorial

You’ll find areas of soggy Considerable in the mid to low elevation shady slopes. There’s no secret here: watch how the snow reacts to your board(s) or ride, and plan your uptracks and exits accordingly to avoid pushing the saturating glop and yourself into a terrain trap or through the trees. This debris sets up like concrete – there’ll be no miraculous self-extrication this go-around.


CURRENT CONDITIONS

Wet, warm and windy. The precipitation seemed hit or miss, with the Provo mountains picking up what looks to be almost a third of an inch of rain up to about 8000’, the Ogden mountains perhaps a third to a half inch of rain, and the Cottonwoods and Park City areas perhaps a tenth of an inch or so. Not that it rained on our parade…..the snow conditions have been deteriorating since Saturday. It is instructive that guide and observer Dan Griffith, who loves skiing as much as anyone, finally had some unprintable things to say about the riding conditions. At least the winds have picked up from the southwest, blowing 20-25mph with the more exposed anemometers spinning at 35-40mph with gusts to 60. Temps are in the low 30’s at 8000’.


RECENT ACTIVITY

Warm temperatures and a high rain/snow line provided a shock to the system of the shady low to mid elevation snow, producing at least one sizeable debris pile. Even a few diehards had to duck to avoid the monster pinwheels they initiated.


THREAT #1

WHERE PROBABILITY SIZE TREND
      Over the next 24 hours.

In the snow and avalanche world, we often find avalanches in areas that see rapid change. Burst in snowfall intensity? Avalanches. Rapid build-up of blowing and drifting snow? Avalanches. Rapidly warming temperatures and/or rain? Avalanches. As they say in the south (and I’m from the south), “if dey ain’t nuthin’ happenin’, dey ain’t nuthin’ gonna happen”. And the converse is true. The southerly and exposed “off” aspects have already been punished by the sun – it’s the northerly and more sheltered aspects experiencing some of the rapid change.


THREAT #2

WHERE PROBABILITY SIZE TREND
      Over the next 24 hours.

Play along the ridgelines long enough and the old saying will hold true: "There's two types of people out there: those that have a cornice story, and those that're gonna." Continue to give a wide berth to the yawning waves.


THREAT #3

WHERE PROBABILITY SIZE TREND
No size identified.
No trend identified.

Low danger - common sense normal caution...stronger winds > potential for smaller wind pockets up high


MOUNTAIN WEATHER

Mild, spotty west to southwest flow. It’s partly cloudy to mostly cloudy and we may squeeze an inch or three at the higher elevations, particularly north of I-80. The rain/snow line should linger at 8000’ and the winds are expected to blow 20-25mph with 11,000’ speeds of 30-35mph. We stay in this pattern for the remainder of the week, with lowering snow levels on Friday/Friday night. Taxes, anyone?
