Kernpunkte

A SIGNIFICANT WINTER STORM WILL ELEVATE AVALANCHE DANGER IN THE BACKCOUNTRY. Heavy snowfall and drifting by winds from the west will cause rising danger throughout the day, and dangerous conditions will likely develop overnight.There is MODERATE danger today in drifted upper elevation terrain. People could trigger avalanches of new snow and/or wind-drifted snow on slopes steeper than about 30 degrees.

  • Evaluate snow and terrain carefully.
  • Avoid travel on drifted slopes at upper elevations.

    The danger of loose and storm slab avalanches will increase as heavy new snow rapidly accumulates on preexisting weak sugary snow. The likelihood of human-triggered and natural soft slab avalanches of storm snow will increase significantly this evening and overnight.

    • Even a small avalanche could be quite dangerous in these shallow snow conditions, because you might be dragged through the rocks or down trees below.
    • Follow safe travel protocols; travel in the backcountry with companions, but cross (or ride) steep slopes one person at a time while the rest of your party watches from a safer place.
    • See video of early-season snow conditions.

    There are areas where people could trigger small wind slab avalanches (around a foot deep) on drifted upper-elevation slopes steeper than about 30 degrees. The danger of wind slab avalanches will become more widespread, and potential avalanches will be larger as the snow is drifted into avalanche starting zones this evening and tonight

The National Weather Service has issued a Winter Storm Warning for the northern mountains, including the Logan Zone, through early Sunday morning. *This from this morning's NWS forecast discussion: "A significant winter storm will impact northern and central Utah through Sunday morning. The potential for unsettled weather continues through the middle of the upcoming week."

In the Logan Zone: Expect snow in the mountains today, heavy at times, with 5 to 9 inches of accumulation possible on upper elevation slopes. High temperatures at 9000' will be near 28° F. Winds out of the west will blow 10 to 14 mph. Tonight, the snow could be heavy at times, and we can expect widespread blowing snow, with 9 to 13 inches of accumulation possible. The temperature will rise to around 29° F by 5 am. It will be quite breezy, with winds from the west-southwest 20 to 24 mph, and gusts as high as 46 mph.

This storm will significantly elevate avalanche danger in the backcountry, and dangerous conditions are likely to develop this weekend.
