Several human-triggered avalanches were reported Sunday and Monday in the adjacent Mt. Baker area. These avalanches occurred on steep wind-loaded slopes. Most avalanches were small, however, one skier-triggered avalanche reportedly ran for over 200ft on a south aspect at 4800ft.
The first week of 2019 brought two potent storms to the region and numerous avalanches. Precipitation favored the western portion of the North Cascades. The first storm brought 6in of water in a two-day period (Jan. 2-4) to areas just north of Hwy 20. Several feet of new snow accumulated above 5500ft, while below, the effects of rain on the snowpack were most significant. The most recent storm (Jan. 5-7) brought 1-2ft of low-density snow above 4000ft and very strong southerly winds.
As we experience a brief break in precipitation on Tuesday, keep in mind:
• Variable winds will continue to redistribute new snow forming fresh drifts, cornices, and wind slabs.
• Avalanche concerns exist within new snow. Mid and lower snowpack layers are strong.
• Snow height increases dramatically as you gain elevation: low coverage below 3000ft and 70-90in on the ground 4000ft and above.
