Observations
In general, from approx 4500 feet MSL via helicopter this west area of Snoqualmie pass had few to no avalanches on north slopes, west, and east slopes that we could find along both north of I90 and south of I90 mountains adjacent to freeway. Temps at 4400 feet were cold 15deg F in early afternoon. Clouds and light mist were prevalent with occasional short sun breaks. The only sluffs we saw were on steep south slopes > 50-60 degrees that were exposed to infrequent sun.
