You'll find excellent cold powder conditions and MODERATE avalanche danger in the backcountry. Periods of heavy snowfall and breezy winds blowing from the southwest will keep today's avalanche danger elevated, especially in drifted upper-elevation terrain. Human-triggered avalanches are possible, with avalanches of wind-drifted snow and cornice falls most likely in drifted upper elevation terrain. Small soft slabs and loose avalanches are possible on slopes steeper than 30° at all elevations with significant accumulations of new snow. Now is not a good time to let your guard down despite the nice powder conditions. Continue to use normal caution; avalanche accidents are quite common in March.
Small soft slab avalanches and sluffs of new snow are possible at all elevations on slopes steeper than 30° with significant recent accumulations.
With more wind moving more snow today, natural and human-triggered avalanches of wind-drifted snow are possible in steep, drifted terrain. Very strong winds over the last several days loaded snow onto leeward terrain, creating thick wind slabs and building out already large overhanging cornices.

No new avalanches were reported recently, but visibility has been limited. Everyone has noted the strong winds from the south and west drifting lots of snow every day since the end of February. Check out all local observations and avalanches HERE.
Yesterday was breezy and snowfall was heavy at times, although we did not see much accumulation on the storm boards (.3" SWE at Tony Grove). We found excellent cold powder riding conditions and good snow stability yesterday in the Central Bear River Range, but poor visibility prevented us from seeing much high drifted terrain. We found 1 to 2 feet of fresh powder capping a widespread dirty and solid crust layer from the warm winds of leap day and March 1st
We have another breezy, snowy, and cold day on tap today that will keep avalanche danger elevated, especially on upper-elevation slopes loaded by the recent strong winds. In drifted terrain, people could trigger 1 to 3-foot thick avalanches of wind-drifted snow, and falling cornices could trigger wind slab avalanches on steep slopes below.
The Tony Grove Snotel at 8400' reports only 3 inches of new snow yesterday, but it seemed like a bit more. It's 14° F and there's 109 inches of total snow containing around 125% of average SWE (snow water equivalent). About 5" of new snow accumulated yesterday at our new Card Canyon weather station and there is 88" of total snow at around 8800' in elevation. At 6:00 this morning winds are blowing from the south-southwest at 32 mph with gusts to 46 mph at the 9700' CSI Logan Peak weather station. At 9500' on Paris Peak, winds are blowing 13 mph from the south-southwest, and it's a chilly 6° F.
Today will bring similar weather to yesterday's. The National Weather Service has issued a Winter Weather Advisory for the Northern Bear River Range (north of the state line). Expect a wintery day in the mountains with high temperatures around 28° F at 8500' and winds blowing from the southwest increasing this morning to 25 to 30 mph. The NWS forecast calls for a possibility of 9 to 17 inches of accumulation on upper elevation slopes today and tonight. Another 5 to 9 inches might accumulate tomorrow, with slightly diminished winds more from the west and a high temperature around 32° F.
A short-lived high pressure starts to move in later in the week, and it looks like fair weather for the coming weekend.
