Tetons

The snowpack is mostly stable this morning. As the day warms, the chance will increase for skiers and riders to trigger isolated pockets of wind slab six to twelve inches deep in very steep terrain, particularly on sunlit aspects. Daytime warming will also make loose snow sluffs and cornice failures possible. Stay off of large cornice features and avoid terrain below them during the heat of the day.

Cloud cover will increase overnight ahead of a Pacific trough slated to quickly move through the region on Saturday. Precipitation will begin in the morning and continue throughout the day. A mix of rain and snow will be possible below 8,000 feet before turning to all snow by the evening. Overnight lows in the mountains will be in the low 20s before rising to near freezing during the day. Southwesterly to westerly ridgetop winds will increase to 25 to 35 miles per hour with gusts to 45.In the Tetons, the general avalanche hazard is expected to be Low Saturday morning and will increase in the higher elevations during the day as shallow wind slabs build upon sun crusts and surface hoar. The general avalanche hazard is expected to remain Moderate in the Togwotee Pass and Greys River areas. There, similar shallow wind slabs will build, and the possibility of triggering deep persistent slabs will linger in isolated areas.
