South Coast

The hazard may go higher than forecast if precipitation amounts are greater than expected.

Fair - Forecast snowfall amounts are uncertain

A series of Pacific cold fronts will move into the area late today ( Friday ) and leave 5 to 10 cm of snow at upper elevations., Winds will be moderate to strong from the south west. Freezing levels should drop to 1000m for the next few days, with daytime heating raising the freezing level to 1500m for Sunday and around 1700m for Monday afternoon.  Monday may see another 5  cm of snow at upper elevations.

Little in the way of avalanche activity from yesterday.  Moist loose avalanches had been reported earlier in the week, but with falling temperatures this activity has gone dormant. Expect wind slab activity with new loading and strong winds.

5 to 15cm of incoming precipitation will fall on a variety of crusts and old surfaces including surface hoar and facets  that formed in sheltered locations during the recent clear weather. Moderate to strong south west winds will redistribute the storm snow into wind slabs on the lee sides of ridge tops. A facet/crust layer that was buried in mid-March is now approximately 50-100 cm down. Recently it was found down 55 cm near the Duffey Lake Road, and produced moderate sudden results. This remains a concern in the region because of it's potential for very large avalanches. Cornices are now large and mature and may collapse with increased loading, possibly triggering the deeply buried weak layer.
