    Mid mountain early Wednesday morning.

    Coming out of the cloud.

    High overcast but good visibility in the alpine.

    Valley cloud eventually lifted and obscured the alpine.

    Whistler peak before lunch.

    It did clear off in the afternoon.

    Great skiing in the steeps.

    High cirrus cloud in the afternoon.

    More cloud later in the day.

Weather Observations for March 29, 2018  taken at 06:00 Hours.

2180 meters     -7, Winds were 25-35 KPH WSW--Whistler Peak
1835 meters     -5, Winds were   5-10 KPH SE    --Roundhouse
1660 meters     -5, trace of new, trace in 24 hrs  Base 303 cm --Pig Alley
  660 meters      0, Valley Temp, Max Temp Yesterday was +9.8, 0.2 mm of precip recorded yest

    As of 07:00 Hrs this am we have mostly overcast skies and variable visibility.


The dirty ridge  and low to the North will give us mostly overcast skies with periods of light precipitation in a Northwesterly flow aloft. The FL will likely go up to 1500 meters by the afternoon and hover in that range into tomorrow.  Friday morning is looking mostly overcast and then the weak frontal band breaks up with some unsettled weather for Friday afternoon into the evening. Another weak frontal band will push through on Saturday in a Westerly flow aloft, it is looking dry so mostly overcast conditions will prevail. Models are not agreeing on the outcome for the weekend, so I am going with overcast skies for Sunday with light snow and the FL dropping to around 800 meters. Unsettled weather is likely for early next week with a weak front arriving Tuesday evening.
Guesstimates: 4-6 cm by Friday morning, trace-1 cm by Saturday morning, 2-6 cm by Sunday morning, 6-12 cm by Monday morning.

    GOES IR image from this am.

     Dirty high will bring slightly warmer temps and overcast skies for today.

    Low has pushed the high just to our South.

    Freezing level should hover just below 1500 meters.

    Fronts along the coast.

    Overcast Friday morning.

    Sunny breaks in the afternoon.


    Most bowls have avalanche debris in them.

    Steeps were skiing well on Wednesday.

Out to Fissile to have a look at what yesterday's winds had done to all that fine pow. Windcrust to 15cm over much lower density on most windward aspects. Crust varied from fully supportive where solar had helped strengthen it to breakable two cm crust on east and west aspects. 
Got one lap on a true south facing slope with two cms of corn overtop of the supportable crust, which did bring back dreams of springtime... 
Skiing was still good on anything with a northern asp factor in it, as was skiing in trees down to 1700m. Windslabs to 60cm evident in isolated areas just below ridgetops, but no recent activity or ski cuts, aside from a Cornice 1.0 natural just below a ridgecrest. 
Not a lot of people out today...

Skier Remote today while making up track in Vista Bowl. Many whumpfs in this area on this aspect. Facet crust combo on non polar aspects. We skied east col spine, Vista chute, and upper husume with wind affected snow but no signs of instability.
