Strong solar input today will produce loose wet avalanches on solar aspects. Storm slabs are still lurking on N-NE Alpine features.
Today starts off cloudy with flurries/showers, making way for sunshine and high-pressure. FL will rise to 1800m, and winds will be moderate from the west. Clear tonight, with another a beautiful spring day forecasted for Thursday. Friday will be a little more unsettled, and the weekend looks wet, with another pulse of precip from the pacific.
A supportive surface crusts caps a mainly isothermal snowpack at TL and below. In the high alpine, 50 - 60 cm recent storm snow is preserved on North aspects, and is sun affected elsewhere over a melt-freeze crust.
3 new avalanches were observed in the HWY corridor yesterday, up to size 2.5 (Rail Road Gunners, MacDgully #7, and Single Bench). A widespread avalanche cycle to size 3 occurred last Friday. On Saturday skiers remotely triggered a size 2.5 slide on the Youngs Peak headwall that 3 people were involved in. All three were unhurt in the slide.
50 cm +/-of storm snow has accumulated in the high alpine over the last 5 days. Recent storm slabs are susceptible to human triggering given the right terrain features and increasing load.
- Be careful with wind loaded pockets, especially near ridge crests and roll-overs.
- Use caution in lee areas in the alpine and treeline. Storm snow is forming reactive slabs.
Aspects: All aspects.
LikelihoodLikely - Possible
Expected Size1 - 2.5
Rain to near treeline and no overnight freeze at 1900m. Expect moist point release slides this afternoon. Low elevation S aspects are rapidly melting back.
- Use extra caution on slopes if the snow is moist or wet.
Aspects: East, South East, South, South West, West, North West.
Elevations: Treeline, Below Treeline.
