Travel & Terrain Advice
Avoid steep south aspect 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.
No new avalanches observed or reported during the past forecast period.
Found on south aspects and at all elevations. Loose wet avalanche problems will present during the height of daytime warming and during periods of direct solar effect. Expect that during warm and sunny periods loose wet avalanches will be present on steep terrain and will be touchy to light triggers. When triggered these avalanches may start small but may have the strength and weight to push a mountain traveler into terrain traps such as cliffs, gullies and trees.
A period of settlement and continued snow pack strengthening has occurred, 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 mid and lower snow pack is well settled and dense.

|Mid||Melt freeze crust and facets buried down between 50 and 70 cm.|
