Summary
Confidence
Fair - Forecast snowfall amounts are uncertain on Saturday
Weather Forecast
A moist unstable southwest flow is expected to continue to bring another 5-10 mm of precipitation combined with moderate gusty winds overnight to coastal areas. A surface high pressure is forecast to follow on Saturday morning that should be a bit drier, but light precipitation is expected to continue for most of the day near the coast. The wind should swing to the southeast and become light with moderate gusts. The interior areas around Smithers should see some broken skies and sunny periods. Another broad low pressure is expected on Sunday that should bring some light precipitation to both the coast and the interior. The next major system is expected on Monday.
Avalanche Summary
No reports of new avalanches from this region.
Snowpack Summary
Moderate-Strong SE-S winds continue to build wind slabs. They may be found in unusual places, lower on the slope or in open areas below treeline. Windward aspects may become wind pressed, and even scoured. North aspects at higher elevations hold dryer, low density snow in the upper 20 cm. Spring-like conditions exist and crusts have formed on solar aspects at all elevations, becoming moist under sunny skies. Melt-freeze conditions exist @ treeline on all aspects. Below treeline has remained moist, with no recovery below 1500 m. The mid-pack is well consolidated. The mid February persistent weak layer, comprised of spotty surface hoar, facets and crusts, is buried 80-120 cm below the surface. No recent activity has been reported on this interface. It most likely needs a large trigger on a specific spot. If an avalanche occurs on this weak interface it will be very large and destructive. Below this the snowpack is well settled and strong. Cornices in the area are reported to be very large. Cornice failure could trigger an avalanche on the slope below.
