Avalanche Forecast

Low - Due to the number of field observations

Another warm and wet system will pummel the South Coast on Sunday before freezing levels drop with moderate snow accumulations into early next week.Sunday: Rain during the day (20-30 mm) before the freezing levels drop to 1000m (and possibly as low as 700m) in the evening with 10-15cm snow overnight. Strong to extreme south winds at ridgetop on Sunday morning. Monday: Flurries, accumulation 10-15 cm. Light to moderate southwest wind. Alpine temperature -1. Freezing level 1000 m.Tuesday: Snow, accumulation 20-30 cm. Moderate to strong south wind. Alpine temperature -1. Freezing level 1200m.

No recent avalanches have been reported. However, the recent rain-on-snow event is suspected to have caused a natural, loose wet avalanche cycle. Although natural avalanche activity and human triggering potential has decreased with cooler temperatures, ongoing rain will maintain the potential for loose wet avalanches, particularly in steep, unsupported terrain. Storm slab development is also a concern at high alpine elevations where precipitation may fall as snow accompanied with strong winds.

There is little information on snowpack structure at this time, except that recent heavy rainfall has saturated the upper snowpack at all elevations and washed away much of the snow at lower elevations. Travel below treeline is becoming more and more rugged, with many open creeks and early season hazards.  Up to 30 cm of heavy wet snow may have fallen at the highest elevations (above 1400m) Friday into Saturday.Snow depth varies from 40 - 130 cm for elevations between 900 - 1200m across the region.
