Avalanche control on WB yesterday produced Sz 1-2 ssl above 2000 meters and wet slabs and loose avalanches below. Sc, Xe, and Xc with a few large cornice releases noted.

For the forecast, the upper level trough will move East this morning with the next slow warm front on its heels. We can expect periods of light snow fall  today with the FL hovering in the 1000 meter range. Marine layer may cause some visibility issues in the lower elevations. The moist westerly flow will continue for the next few days with fluctuations in the FL. Range is not terrible with lows of 1500 meters and highs of 1800 meters. Sunday and Monday will see a weak warm front move through with light precipitation. A wetter frontal wave arrives for Monday evening with heavy snow forecasted above 1500 meters. Tuesday at his time shows a weaker front with light precipitation during the day and moderate snowfall in the evening. There is little agreement amongst the models beyond Tuesday so stand by!! Guesstimates: 8-10 cm by Sunday morning, 4-6 cm by Monday morning, 20-30 cm by Tuesday morning.

    Overcast for today with light snowfall.

    Very slow moving front Sunday.

    Moist West flow for Monday and Tuesday.

    Still early but cooler moist flow from the Northwest Wednesday and Thursday.
