Salt Lake Avalanche Advisory

Forecaster: Bruce Tremper

SPECIAL ANNOUNCEMENT

Through a generous donation by Backcountry.com to our partners the Friends of the Utah Avalanche Center we will continue forecasting until April 24th. I will issue a combination of early morning weekend forecasts and mid week afternoon updates, with weekend only updates for the Logan and Uintas area mountains. Thank You!!


BOTTOM LINE

Danger by aspect and elevation on slopes approaching 35° or steeper.
(click HERE for tomorrow's danger rating)


Danger Rose Tutorial

The avalanche danger is mostly MODERATE (Level 2) for lingering wind slabs in mid and upper elevation, wind exposed terrain and MODERATE (Level 2)for wet, loose avalanches as the steep, sun exposed slopes as they heat up in the sun.


CURRENT CONDITIONS

There was a couple inches of snow today at higher elevations in the Salt Lake area mountains with about 4 inches in the past 24 hours. But the winds blew hard this afternoon with the passage of some thunderstorms and there was quite a bit of drifting. Temperatures stayed cool with freezing levels nearly to the valley floor.


RECENT ACTIVITY

With the strong winds this afternoon there was fairly widespread soft, wind slabs from both explosive triggered control work and reported from the backcountry. One skier on Flagstaff, north of Alta triggered a wind slab but was luckily able to escape to the side. Click HERE for a report from Flagstaff.


THREAT #1

WHERE PROBABILITY SIZE TREND
      Over the next 24 hours.

The main problem you will find on Friday is the lingering wind slabs from today's wind. As is often the case this time of year, they settle out fast but watch for lingering sensitivity. It's easy to recognize them by their smooth, rounded shape, their punchy feel and they will sometimes crack and sound hollow.


THREAT #2

WHERE PROBABILITY SIZE TREND
      Over the next 18 hours.

With a nice sunny day expected on Friday that strong, spring sun will beat down on the fresh snow making it turn soggy in a hurry. As always, avoid steep slopes when they get wet in the heat of the sun.


MOUNTAIN WEATHER

We will have perhaps 1-3 more inches of snow overnight. Then for a change, we should have a nice, sunny day on Friday with ridgetop winds from the west around 10-20 mph. Ridgetop temperatures should top out around freezing with 8,000' temps around 35-40 degrees.

Enjoy it while you can because--you guessed it--yet another disturbance will arrive for Saturday and Sunday bring more light snow showers at upper elevations and light rain showers at low and mid elevations. We may be able to squeeze 8 more inches of snow out of this weekend's storm.
