April 20, 2015


    Early Sunday morning April 19, 2015--Last day for some great conditions on Blackcomb.

    Dry winter snow conditions on the Horstman Glacier. Spring conditions on Southerly slopes.

    Evidence of small point releases.

    Last day for easy access into the Blackcomb side of the Spearhead.

   A recent slab avalanche near Hourglass Peak in Garibaldi Park.

    Sunset Sunday evening.


Weather Observations for April 20, 2015; taken at 06:00 Hours.

2180 meters     +4, Winds were 10-15 KPH from the SE
1835 meters     +5, Winds were calm?
1650 meters     +4, No new snow, Base 182 cm.
  660 meters     +2, Valley Temp, Max Temp Yesterday was +21.2.

    As of 07:00 Hours this am we have sunny skies, unlimited visibility and some broken cirrus cloud.


For the forecast, the ridge of high pressure aloft will give us one more day of dry sunny weather in a Westerly Flow aloft with freezing levels rising to 2800 meters today. The ridge will shift East early Tuesday morning and usher in some cooler marine air and cloud to the area Tuesday afternoon. We can expect typical spring weather for the remainder of the week as several Pacific frontal bands move onto the coast. The front on Tuesday with the associated cold front will bring cloud to the area moving onshore in the evening. The FL should drop to about 1500 meters by Wednesday morning, cloudy conditions will prevail for Wednesday with some light intermittent rain during the day. A very weak ridge tries to build for Wednesday evening into Thursday morning with unsettled conditions. Another cloudy day by Thursday afternoon remaining that way into Friday. A stronger front is  expected for Saturday into Sunday.  The FL will range from highs of 1700-1800 meters to lows of 1200-1400 meters through this time period, so we can expect light snow in the alpine.


    High is still pushing frontal bands to the North.

   This front will slip down the coast tomorrow bringing cloudy conditions and light precipitation.


    Cloudy and moist for Wednesday.

    Some breaks Wednesday evening into Thursday morning.

    Frontal wave should aerie Thursday afternoon.

   Looking wetter over the weekend.
