-- ARCHIVED ADVISORY --
All advisories expire after 24 hours from the posting date/time. Summit Lake advisories are issued on Saturdays.

Saturday, November 17th 2012

Created: Nov 17th 6:43 am

Summit Lake Advisories will be issues on Saturday at 7am starting today.
BOTTOM LINE
Summit Lake Area has had minimal snowfall with 2-5 inches in the last week. Some wind loading was observed on Friday but no recent avalanche activity could be seen. The snowpack is thin to non existent on South and East aspects. On North and West aspects it is slightly better but snow line starts around 2800 feet with ridges windswept. The biggest problem today for Summit would be walking up to the snow that is between 2800-3000 feet in many areas.

ANNOUNCEMENTS
Don't forget to check the photos/observations page for early season information. Also, the calendar page is filling up with free awareness classes and other avalanche education courses offered in our area.

SNOWPACK and AVALANCHE DISCUSSION
At upper elevations wind loading from the North was observed blowing many of the upper slopes bare. Some loaded gullies have thin soft slabs on top of faceted snow that could produce human triggered avalanches but this would be limited to upper elevations in loaded gullies and slopes. Many of these slopes have snowpack that becomes thin very quickly and would make exiting difficult so plan your route before you go. It might save a difficult ski/walk back up or a long walk out.

MOUNTAIN WEATHER
Weather for today is colder with temperatures at Summit Lake currently -5F with light winds N-NW with a peak gust of 26mph out of the W. Past 24 hours had a low of -5 and a high of 28. The next storm is forecasted for Sunday with up to 2” of new snow.
