Be careful as you transition into wind-affected terrain.

In sheltered areas, a persistent weak layer may remain triggerable.

No new avalanche activity has been confirmed since last weekend, but reports have been limited in this region.

Looking forward, we expect naturally triggered avalanches to be unlikely, but human triggering to remain possible.

Wind-effect has been extensive, and wind slabs can be found on various aspects extending well into treeline features. 20 to 60 cm of snow accumulated over the last storm cycle, with the highest amounts falling in the western parts of the region and lowest near Manning Park. A few flurries totaling 2 to 8 cm are expected tomorrow. The old storm snow is sitting on a weak layer that developed in late January. In many areas, this layer consists of a hard crust. However, on shady, upper-elevation slopes, the new snow may be resting on faceted grains or surface hoar. A crust from December is buried 80 to 120 cm deep and may have facets around it in shallow areas. Otherwise, the lower snowpack is well consolidated.

Friday Night

Partly cloudy. 30 km/h southwest ridgetop wind. Treeline temperatures -13 °C.

Saturday

Cloudy with 2 to 8 cm of snow. 15 to 25 km/h west ridgetop wind. Treeline temperatures -11 °C.

Sunday

Mostly cloudy. 10 to 15 km/h variable ridgetop wind. Treeline temperatures -13 °C

Monday

Sunny. 40 to 50 km/h northeast ridgetop wind. Treeline temperatures -18 °C

• Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
• Fresh snow rests on a problematic persistent slab, don't let good riding lure you into complacency.
• Keep in mind that human triggering may persist as natural avalanches taper off.
