Sea To Sky

Continued warm temperatures should allow the snowpack to further settle and stabilize, but small storm slabs in more extreme terrain may still be an issue. Watch for the odd loose wet avalanche on steep solar aspects in the afternoon too.

High - Timing, track, or intensity of incoming weather system is uncertain on Friday

Temperatures along the coast have moderated and this trend is expected to linger into Wednesday as a southwesterly flow of mild Pacific air continues. Those hoping for fresh snow will have to wait until late in the week.WEDNESDAY: Clear skies, light temperature inversion with the freezing level around 2500 m, very light southeast wind, no snow expected.THURSDAY: Overcast, light temperature inversion with the freezing level around 2500 m, light south/southwest wind, 1 to 3 mm of precipitation possible.FRIDAY: Overcast, freezing level around 2000 m, light to moderate south/southwest wind, 3 to 7 mm of precipitation possible.

On Tuesday snow balling and pin wheeling was reported from north facing aspects. On Monday several loose wet avalanches to size 1 were reported from southeast and south facing features between 1800 and 2100 m. On Sunday there was one report of a size 2.5 natural avalanche on a steep east facing feature in the alpine. There was also a small skier triggered avalanche on a southeast facing moraine feature at 1800 m. Loose dry avalanches to size 1 were reported from a variety of aspects.

On Sunday a slight crust began to form on south and southwest facing aspects as warm temperatures and sun combined to moisten the snow surface. By Tuesday the upper 5 cm of the snowpack had started to become moist, even on upper elevation northeast facing features. Last Thursday and Friday two successive storms produced 50 to 70 cm of snow with wind mainly out of the south. The new snow rests on a variety of old surfaces including crust on solar aspects, old wind slabs, facets and isolated surface hoar below treeline, but avalanche activity on this interface continues to decrease as time and warm temperatures allow the old storm snow to settle and gain cohesion. Wind effect in the alpine has been extensive but reported wind slab avalanche activity has ceased.40 to 100 cm below the surface there is a widespread melt-freeze crust that was buried on December 15th. This layer has not produced much in the way of avalanche activity and is likely trending towards dormancy. Beneath the mid-December crust, the lower snowpack is generally strong and well settled.
