Please provide details to help us determine the weather and snowpack during the time this observation took place.

Heavy rain along Turnagain Arm up to 1,000'. Heavy snowfall above 1,000'. Strong winds along the Arm but once on the Pass winds were light. Ridgetop stations still reporting very strong Easterly winds however. Temperatures in the mid 30's F.

Snow surface

2 feet of unsupportable, very wet and heavy snow at the road along Turnagain Pass at 1,000'


Clearly a very unstable snowpack today. Numerous debris piles seen from the road - some of these released during the mid-day hours. Visibility was too poor to view anything above treeline.
