Advisory: Logan Area Mountains | Issued by Toby Weed for Thursday - March 2, 2017 - 6:08am |
---|
current conditions We are finding deep and generally stable snow on most slopes, but drifting from Tuesday's westerly winds created heightened cornice fall and wind slab conditions in exposed upper elevation terrain. The Tony Grove Snotel at 8400' reports 125"of total snow with 166% of average SWE (Snow Water Equivalent). It's 10 F at the 9700' CSI Logan Peak weather station, and the wind is blowing 9 mph from the west. Mt. Gog from White Pine Knob (2/26/17) |
recent activity No new large avalanches have been reported or observed, but there was some natural wind slab, cornice fall, and loose activity during the storm Monday and Tuesday. |

Huge, overhanging cornices can break further back than expected and trigger avalanches on slopes below. Solar warming and rising temperatures may cause some cornices to naturally buckle and calve. |

description
Clearing skies and warming temperatures will create heightened wet avalanche conditions on sunny slopes. Loose wet avalanches entraining significant piles of moist fresh snow are possible with midday solar warming. If you start to see roller balls, pin wheels, or natural sluffs, it's time to leave. Avoid being under steep slopes with saturated surface snow. |
weather An increasingly dry and warmer westerly flow aloft will set up for the latter half of the week. Precipitation could return to region late in the weekend with the arrival of a cold front. |
