Avalanche Forecast
Issued: Jan 30th, 2019 4:21PM
The alpine rating is Storm Slabs.
, the treeline rating is , and the below treeline rating is Known problems includeVariable amounts of snow will fall in the region on Thursday. Where it accumulates, the snow may not bond well to underlying layers and be reactive to human traffic.
Summary
Confidence
Moderate - Timing, track, or intensity of incoming weather system is uncertain
Weather Forecast
WEDNESDAY NIGHT: Cloudy with snowfall, accumulation 5 cm, freezing level below valley bottom.THURSDAY: Cloudy with snowfall, accumulation 5 to 10 cm, light to moderate southwest winds, alpine temperature -4 C, freezing level below valley bottom.FRIDAY: Cloudy with snowfall, accumulation 5 to 10 cm, light to moderate south winds, alpine temperature -15 C, freezing level below valley bottom.SATURDAY: Mostly cloudy with light snowfall, trace accumulation, light southwest winds, alpine temperature -25 C, freezing level below valley bottom.
Avalanche Summary
No new avalanches were observed in the region on Tuesday.
Snowpack Summary
New snow will fall onto a wind-affected surface in high alpine, a widespread melt-freeze, and feathery surface hoar crystals in sheltered areas.In the south of the region, the remainder of the snowpack has been reported as generally well-settled.Around and north of Hazelton, 40 to 100 cm of snow may overly two weak layers of surface hoar in sheltered and shaded areas. A weak layer of sugary faceted grains may also exist, approximately 150 to 200 cm deep.
Problems
Storm Slabs
The new snow may be touchy, as it may not bond well to the layers it is falling on. Assess for the bond of the snow before committing to avalanche terrain.
Be careful with wind-loaded pockets adjacent to ridge crests and roll-overs.Watch for signs of instability such as whumpfing, cracking, or recent avalanches.Make observations and assess conditions continually as you travel.
