Tetons

The General Avalanche Danger at mid and upper elevations is MODERATE. The weekend snow and more recent wind transport have created soft surface slabs up to eighteen inches in depth that could be triggered on steep, wind loaded slopes. Some potential remains to trigger deeper hard slabs to eight feet in depth by larger triggers, or in extremely steep terrain over rocky areas where shallow trigger points can be found. Avalanches are unlikely at low elevations today.Special Note: Teton Pass will be closed 3AM Wednesday morning for avalanche control.

Heavy snow and high winds are expected tonight through Wednesday. As much as 20 inches of new snow could fall in the mountains by Thursday morning. Winds are expected to be southwesterly tonight, veering to westerly tomorrow and blowing at forty mile per hour averages with gusts in the sixties. Temperatures Tuesday night and Wednesday will be in the low to mid twenties.AVALANCHE HAZARD FOR THE TETON, TOGWOTEE PASS/CONTINENTAL DIVIDE AND GREYS RIVER/SOUTHWEST TRAILS AREASThe general avalanche danger (now MODERATE) is expected to increase Wednesday at the mid and upper elevations in the Tetons and Greys River/Southwest Trails areas. Sensitive slabs to eighteen inches in depth may be easily triggerd tomorrow morning and the size of those slabs will increase through the day. Low elevations may remain at LOW hazard depending on the final numbers. A chance remains to trigger deeper hard slabs in extremely steep terrain. Less snow is forecasted for the Togwotee Pass area where the hazard will likely stay at MODERATE.Backcountry users are advised to consult area specific forecasts issued every morning as new information may become available and unexpected weather can change conditions.
