Avalanche Danger Update

Dangerous avalanche conditions exist throughout Southcentral Alaska.

Recent strong winds and localized areas of heavy snow have increased avalanche danger throughout the region, and dangerous avalanche conditions exist in many areas (especially higher elevation terrain where more wintry conditions exist and recent precipitation has accumulated as snow).

Alpine observations have been limited for over a week due to persistent stormy weather.  Expect significant recent snow and wind loading in upper elevation areas.

Dangerous avalanche conditions have been reported in the Hatcher Pass area Talkeetna Mountains north of Anchorage near Palmer, in areas of Chugach State Park from the Knik River to Girdwood, and from Turnagain Arm through the Kenai Peninsula in areas of Chugach National Forest.

If the weather improves this week and becomes more conducive to alpine recreation, approach avalanche terrain with caution.

Keep in mind that most mountainous areas in the region have received at least some new snow in the past week that has not yet been exposed to significant sunshine.  When fresh snow on steep terrain is first exposed to the significant solar radiation, expect natural wet avalanche activity.

Beware that many popular trails in the region (e.g. Gold Mint – Hatcher Pass, Twin Peaks – Eklutna Lake, Powerline – Glen Alps, Falls Creek – Turnagain Arm, Crow Pass – Girdwood, Byron Glacier – Portage) are exposed to potential deadly avalanche terrain.  Even if you’re on flat and snow-free ground, it’s important to be mindful of what’s above you this time of year.  If there is steep, snowy terrain overhead; make sure you are not in an avalanche path/runout zone.
