    First indicators of this problem showing up. Easy enough to avoid but, larger slides, triggered in the deep weaknesses can quickly become a significant issue for groups traveling in the valley bottoms or run outs.

  • Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque

    This problem has been most active in the Whistler/Portal Creek area but is widespread through the forecast region and when triggered, always goes big.

  • Loose Wet

    Subject to intense periods of solar radiation. The overall snowpack is shallow and it does not take long for the Sun to make a significant impact to the hazard rating.

Weather Forecast

Cool overnight temperatures. Apparently... forecasts calling for 6cm overnight, we'll see I guess. Cooler then originally forecast for Friday with freezing levels rising to 1800ms and Alpine temperatures -3. Moderate and gusty W-ly winds through the day Friday.

Snowpack Summary

Moist surface snow and, where a shallower snowpack exists, isothermal conditions BLT on solar aspects with some recovery overnight. Overall, the snowpack is shallow everywhere but, there is significant variation through-out the forecasting area. The persistent slab, down 30-70cms has been most active in the surrounding area off the ski hill.

Avalanche Summary

Field team in the Icefields area report only minor pin-wheels and snow-balling on immediate solar aspects.
