Problem Details

Fresh storm slabs 30-90cm thick are lingering from yesterday. The new snow is upside-down (weak at the bottom and heavy/wet at the top) which makes it prone to avalanche. It will take some more time for these fresh storm slabs to bond and settle.

Strong south winds last night will have heavily loaded north aspects, and gullies/terrain features on east and west aspects. These areas will be quite dangerous with thick slabs that are still settling and adjusting. Pockets of HIGH danger will linger on wind loaded slopes steeper than 35 degrees, and under cornices.

Recent Avalanche Activity

Recent Weather

 

Tuesday’s storm hit hard with 2-3″ of precipitation in about 12 hours. Mt. Ripinsky station recorded a quick 19″ of new snow, with around 21″ in the Glacier Creek area. Similar (or slightly higher) amounts are expected at the Pass. Winds started northerly 20-30mph and jumped to southerly 40-60mph Tuesday evening.

Wednesday will be a break between storms, with cloudy skies, cooling temperaures, and light south winds.

The next front moves in early Thursday morning, bringing around 1″ of precipitation and southerly winds. Snow levels will start at sea level and rise to 1200ft.

Another very strong storm is likely Thursday night-Friday. Indications are it could be stronger than the Tuesday system and possibly with more north winds and lower snow levels. Stay tuned.

Additional Info & Media

Be extremely cautious venturing into the backcountry right now. There is a lot of new snow and human triggered avalanches are likely until the snow has more time to settle. Even small slides can pile up deep. Stay out of gullies, depressions, and terrain traps.
