Fall Avalanche Statement 

Daily avalanche advisories are planned to resume in mid November or later as conditions dictate. Occasional intermittent early season updates to this page may occur earlier if conditions warrant and resources are available.

Today the avalanche danger should remain LOW for all elevations and aspects due to light winds, little new snow accumulation, increased cloud cover, and cooler temperatures. Large, dangerous avalanche activity will remain unlikely but not impossible. This will be the last advisory of the 2010-2011 winter. The observations pages will remain active so please continue to share your backcountry observations here: snowpack obs, avalanche obs. Thanks to everyone who makes the avalanche center possible.
