FORECAST:

The broad upper level low will bring unsettled weather to our zone for the next few days. Today should be mostly sunny but with this pattern its difficult to know exactly the timing of the breaks and flurries. The upper flow will be Southwesterly switching to Easterly this evening.  The freezing level may go up to 1300 meters. Monday is looking more cloudy than sun, with some flurries possible. Tuesday as well. Wednesday is looking unsettled.  A more organised front should arrive Thursday night for some needed snow as a deep upper low sends us a pacific front. Friday is looking unsettled as well.
Guesstimates: 0 cm by Monday morning, trace-1 cm by Tuesday morning, 2-6 cm by Wednesday morning, 2-6 cm by Thursday morning, 10-15 cm by Friday morning.

Quick trip report from a Black Tusk ascent on March 15th. Snow conditions ranged from bullet proof down low to wind crust up high with variations of powder/sun affected in between. We began skinning about 2km up the switchback trail. Snow seemed stable, however there are large cornices on the tusk and col below it. Chimney is in good condition with plenty of stability for booting. Get after it while the skin track and boot pack are still in place! Thanks to the two guys who beat us to the punch in the morning and laid in the track, you're the real MVP. Pro tip: don't drive up to the lot regardless of how sweet you think your 4X4 is. We got to spend a lovely 4 hours waiting for some of Whistler's finest to get up to us and winch us out of snow once it had hardened in the evening.

Melt-freeze conditions in the North Shore at the moment, which made for quick travel along the HSCT. We skiied down out below Lions around 12:30 pm and it was still quite firm. Bootpacking begins shortly below the bridge over Harvey Creek, i.e. below about 800 m elevation.
