Tetons

An unstable wet loose snowpack exists below an elevation of 8,000 feet. Yesterday a slide occured in the Cow of the Woods avalanche path at 2 PM. With warm temperatures and rain in the forecast natural wet snow avalanches could occur on steep snow covered slopes. Avalanches are unlikely above an elevation of 9,000 feet where temperatures are cooler.

A storm system will bring snow and possible thunderstorms Sunday night and Monday. The Tetons, Salt and Wyoming ranges could see 4 to 8 inches of snow by mid day Monday. The Togwotee Pass/Continental Divide area could receive more. Mountain temperatures will rise from the upper teens in the morning to the low 30s during the day. Temperatures on lower slopes should rise from the mid 20s into the mid 30s. Winds will be northwesterly overnight at 20 miles per hour then back to northeasterly at 25 Monday morning.The general avalanche hazard is expected to be Moderate Wednesday above 9,500 feet as new snow and winds may create user triggered soft slabs to a foot in depth on steep, lee slopes with smooth sun crusts. Areas below 9,500 feet should remain cool enough to keep the hazard at low.
