Danger Rose Tutorial

For Thursday , April 9: Pockets of CONSIDERABLE danger exist in this morning’s window of heavy snowfall with the expectation of a few hours of stronger northwesterly winds. This danger is more pronounced in the Ogden and Provo area mountains I and would expect stabilization to improve into the afternoon.

For Friday, April 10: Mostly LOW with pockets of MODERATE for any lingering instabilities with Thursday’s storm snow. Any periods of sun will exacerbate the wet activity on any and all sun exposed slopes.


Populists tend to love the west to southwest flow as snowfall amounts are often pretty evenly distributed. Totals are 6-10” across the range and it’s still snowing. Densities belie the rimed nature of the new snow, particularly in the outlying areas – and one might expect heavy amounts of graupel in localized areas. With the storm moving off to the east, winds are now from the west northwest blowing 15-20mph with the 11,000’ stations blowing 25mph with gusts to 35. Temps are in the mid-20’s. Riding conditions should again be quite good as the heavier snow and graupel provide a good spongy buffer over many of the old crusts.


Quiet in the backcountry yesterday.


      Over the next 16 hours.

Generally speaking, warm new snow tends to bond well to a warm, corrugated base, but it may all be academic with localized areas of strong snowfall intensity and potential for stronger winds for a few hours this morning at the higher elevations. Regardless, simple hand shear tests, pole-isolation tests, cornice drops and ski cuts should provide necessary information. When asked if it’s gonna rain, the answer is often, “well, son, that depends on the weather”.. and it usually placates the questioner. It’s no different with this morning’s avalanche report…..”is it gonna avalanche?”….”well, that depends on the weather”. Watch for changing conditions. Keep an eye on the snowfall rates and increase in wind speeds.

Graupel often bounces down the steepest slope angles and pool at the lower angle transitions or at the bases of cliff bands and may be triggered by the unwary who has skied or ridden the steeper slopes above.


Snowfall is likely to persist into the late morning with showers likely into the afternoon. Winds may spike into the 35-40mph ranger this morning along the high ridgelines, but should be in the low to moderate range by the afternoon. Temps will be in the low 20’s at 10,000’ and upper 20’s at 8000’. We’ll have a break tomorrow with a weak cutoff Low system moving through over the weekend. A moist westerly flow persists into next week.

Beacon training parks are up and running! There is one at Snowbasin, one on the Park City side at the top of Canyon’s gondola toward the Tombstone lift, one in Little Cottonwood near the Snowbird parking structure on the bypass road, and in Big Cottonwood a training park is at the west end of Solitude's lower parking lot.
