In sintesi

HIGH AVALANCHE DANGER

Avoid all avalanche terrain which means slopes steeper than 30˚.

Avalanches can be triggered from a distance right now so avoid being below steep slopes where an avalanche could come down on top of you.

    It's real simple today. There was a preexisting sugary weak layer buried deep in the snowpack and we've just clobbered it with a ton of snow and water weight. All steep slopes are suspect no matter which direction they face.

    This large amount of snow will be just what we needed to strengthen the buried Persistent Weak Layer from November but it will take a little time for everything to settle.

    Long term; we should have a stable snowpack.

    SHORT TERM; THE SNOWPACK IS UNSTABLE.

    The new snow itself could be unstable. There was some natural avalanche activity noted on Saturday involving just the new snow. The only choice right now is to avoid being on or below any steep slope.

Avalanche Warning

* WHAT...The avalanche danger is HIGH across northern, central, southeast, and southwest Utah.

* WHERE...For most mountains in Utah and southeast Idaho, including the Wasatch Range, Bear River Range, Uinta Range, Manti-Skyline, Fish Lake Region, La Sal and Abajo Mountains of Southeastern Utah, Pavant Range, Tushar Range, and Cedar City area mountains.

* WHEN...In effect from 6AM MST this morning to 6AM MST Tuesday

* IMPACTS...Very dangerous avalanche conditions exist. Natural and human triggered avalanches are likely on many slopes and may be triggered at a distance. Stay off of and out from under slopes steeper than 30 degrees.

Snow and Weather

Current Conditions: Wow. Storm totals for snow and water content are astonishing. Over 5 feet of snow has fallen since Wednesday in the Fairview Lakes zone. Farther south, totals are in the 3 foot range or a bit more. The Skyline picked up about another foot of snow in the last 24 hours. Temperatures have cooled to around 20˚F and the snow densities are much lighter now. The wind has been pretty light over the last 24 hours. It was from the east on Sunday and has switched back to the west this morning.

Mountain Weather: The storm is starting to taper off but we still have snowfall as of 7am. We'll see cloudy skies today with the chance for periods of light snow. Temperatures will be in the teens and wind will be light from the west northwest. It looks like clouds will hang around Tuesday with light snow flurries possible. Overall the weather pattern looks quite active over the long term. The next storm is shaping up for around Friday.
