Tetons

Last night's warm temperatures and today's rain showers will keep the wet snow avalanche hazard elevated below an elevation of 8,500 feet. Wet slides are possible on very steep terrain features. Avoid steep slopes where snow surfaces are wet and unconsolidated. Colder conditions are expected at the higher elevations where the hazard is expected to be low. Up there monitor conditions for increasing new snow hazard if you encounter areas of localized heavy snowfall, especially if that snow is accompanied by strong winds and drifting snow.

As the weather system exits to the east, rain and snow showers will taper off and cloud cover will decrease. Tomorrow skies are expected to be partly to mostly cloudy over the mountains. At 10,000 feet, overnight temperatures are forecasted to drop into the 20s and then rise into the upper 30s. Valley lows are expected to be in the upper 20s and then warm to 50. Northwesterly ridgetop winds will be 15 to 25 miles per hour tonight, and then by the morning should back to the west and lessen. Freezing temperatures overnight will form surface crusts and decrease the wet snow avalanche hazard. Depending on the length of the freeze, it will determine how quickly the hazard will increase as the snowpack becomes unconsolidated. The general avalanche hazard is expected to be moderate. Wet snow avalanches will be possible below 8,000 feet and on solar aspects above this elevation. In the Tetons and Southwest Trails forecast areas, backcountry travelers could trigger isolated wind slabs 12 inches deep on wind loaded slopes above 9,000 feet. The likelihood of triggering these slabs will increase as the day warms.
