Detailed Forecast
Northwest winds and heavy snow is being seen at Mt Hood on Sunday.About 15 inches of storm snow has accumulated since the storm began yesterday.Snow is much heavier at Mt Hood Sunday than the rest of the forecast area.
With these snowfall and loading rates new storm and wind slab is certain on Sunday. Back country travel in avalanche terrain is not recommended especially in the near and above treeline on Sunday. The surface hoar will increase instability where it gets buried intact.
It will also take longer for some stabilizing at Mt Hood than the rest of the forecast area since stronger winds and heavier snowfall should last longer there on Sunday.
Snowpack Discussion
A cooler period with little precipitation was seen about Thursday to Friday. Some skiers were reporting better conditions on lower angle slopes with skis scraping crusts on some steeper slopes. Surface hoar is possible from Thursday night.
A cold front is moving over the Northwest on Saturday and Saturday night causing west winds and moderate to heavy snow and snow showers and a cooling trend. This should build some new wind and storm slab especially at Mt Hood by Sunday.
