Provo Avalanche Advisory

Forecaster: Bruce Tremper

BOTTOM LINE

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

Danger Rose Tutorial

The avalanche danger today is mostly LOW. But remember that low danger never means no danger. The places where you might find an avalanche today would be if we get more than a couple inches of new snow with wind, avoid steep slopes with recent wind drifts. Also, in thin, steep, snowpack areas there may be just enough soggy snow under the surface crusts to produce lingering, wet activity on steep slopes.


CURRENT CONDITIONS

If you blinked yesterday you would have missed our big snowstorm, which dumped a mighty inch of new snow. The Uinta Mountains got 5 inches of snow. But hey, at least the winds came up and it got cold. Temperatures have plummeted overnight, down to 7 degrees on the highest peaks and 20 degrees down at 8,000’. Winds blew overnight 20, gusting to 30 but winds have since dropped. Snow surface conditions include rock-hard sun crusts on most aspects that can rattle your fillings loose. There are breakable crusts on east and west facing and there are rumors of a few scraps of powder on upper elevation, straight north, steep slopes and I actually found about 5 turns yesterday.


RECENT ACTIVITY

The only activity yesterday was wet loose avalanches during daytime heating and in the thin snowpack areas on steep slopes on Mt. Timpanogos, some of these stepped down to the ground in larger, wet slabs. The Wasatch Powderbird Guides noticed one in process as they flew over Timpanogos yesterday around noon. Today’s cold temperature should put the kibosh on them.


THREAT #1

WHERE PROBABILITY SIZE TREND
      Over the next 24 hours.

I’m not expecting much, if any, avalanche activity today of any kind and I’ve bravely colored in green on all aspects and elevations. But remember that low danger never means no danger. The places where you might find an avalanche today would be if we get more than a couple inches of new snow with wind, avoid steep slopes with recent wind drifts. Also, in thin, steep, snowpack areas there may be just enough soggy snow under the surface crusts to produce lingering, wet activity on steep slopes.


MOUNTAIN WEATHER

Very cold today. A cold pocket of air sliding down from the north should destabilize the air to produce springtime convective snow showers this afternoon. We may get a couple inches of snow in the Wasatch Range and the Uinta Mountains may get 4-8 inches with the greatest amounts on the eastern end of the range. Some of these convective showers may even produce a bit if lightning. Ridge top temperatures should be around 10 degrees with the mid 20’s down at 8,000’. Ridgetop winds may pick up and blow harder, 25, gusting to 35 from the northwest.

We have rapid warming for the weekend and then another weak storm for about Tuesday.
