Travel & Terrain Advice
Remain vigilant of changing conditions and tailor trip plans to start early and avoid steep slopes during daytime peak warming periods. Expect that direct sunshine will immediately effect and unconsolidated the upper snow pack, Avoid sun exposed slopes when the solar radiation is strong, especially when the snow is moist or wet.
Natural loose wet size 1 on steep solar aspects at tree line has been reported.
Found on all aspect, especially south and at all elevations. Loose wet avalanche problems will present when temperatures warm and during periods of direct solar effect. Expect that during warm and sunny periods loose wet avalanches will be touchy to light triggers and if triggered it will be possible to produce large avalanches up to size 2.
A cycle of daytime warming and overnight cooling is turning the upper snow pack moist and wet in the daytime and becoming a very hard and supportive melt freeze crust during the overnight period. The facet crust still presents but is currently non reactive. It may need a heavy load such as very warm temperatures combined with heavy rainfall to trigger, expect this weather format to effect the snow pack in the later spring months. The mid and lower snow pack is well settled and dense.
|Surface||Moist surface conditions becoming a melt freeze crust during over night cooling.|
|Mid||Melt freeze crust and facets buried down between 50 and 70 cm.|
|Lower||Well settled and dense.|
Clear and sunny daytime conditions with cool overnight temperatures.
